Introduction / Overview

The 9325-NU (Portable Sensor Display Standard) for strain bridge sensors is a microprocessor based portable

display instrument designed to interface with any full bridge sensor with an output sensitivity of up to 480mV/V.

Bridge resistances from 85 ohms upwards can be used with the 9325-NU.

This module can be either used as a handheld device or, using the optional mounting accessories, or attached to

equipment, dashboards, walls, or desks.

Configuration and calibration of the 9325-NU is achieved by using the front panel keypad menu system.

User functions available on the 9325-NU include:

•

Range Selection

•

Gross/Net indication selection

•

Min/Max

•

Units

•

TEDS support

The 9325-NU is powered by two internal non-rechargeable AA alkaline batteries.

Key Concepts

Calibration Ranges

There are six calibration ranges available that can be individually calibrated for use with strain bridges that do not

have TEDS capability.

These ranges can be used for connecting to different strain bridges or for different sections of the same strain

bridge i.e., one for compression and one for tension. The ranges are user selectable and independent of what is

physically connected to the handheld.

The number of ranges available and the ability to switch between these ranges can all be controlled when

configuring the handheld.

Each of these ranges will remember settings that contribute to the user experience so for settings such as

selected units and tare values etc. these will be remembered and reused as each range is selected again.

Note: The 9320-NU only allows for calibrations with a live load. If mV/V entry calibration is needed, please

contact Interface Inc, and we will provide you with a method to achieve this.

In addition, there is also support for TEDS calibration tables in TEDS capable connected devices where the

calibration information is held in the connected sensor. The user experience settings will be remembered for the

last twenty connected TEDS sensors. There is an option to disable TEDS support on a particular TEDS enabled

sensor so the handheld calibration ranges can then be used instead.

Decimal Point Position and Resolution

Because the 9325-NU can handle so many engineering units out of the box and allow conversion between

suitable units the way it handles decimal point positions and resolution (For displays) needed a complete

overhaul compared to the original 9320.

On the original having only two calibration ranges (And no concept of engineering unit conversion), each range

had its own formatting settings for decimal points and resolution and these ranges were very often used to

deliver results from the same strain bridge sensor in two different engineering units.

The new 9325-NU has six calibration ranges available where each can automatically convert between the

calibrated units and any other unit the user wants to display the values in. Therefore, because each calibration

range can display a whole range of engineering units (Although this can be limited by the user it still has that

capability) setting the decimal position and resolution per range does not work anymore. I.e. changing from

grams to tons would be nonsensical if they both shared the setting for 1 decimal place for example. This is even

worse for resolution settings when switching between kg and lbf as the display would no longer count in

increments suitable for both units.

So, the 9325-NU now supports settings for both decimal point position on a per unit basis and resolution on a per

calibration range basis.

Out of the box the decimal point position for all units has a sensible default but these can easily be changed

using the keypad (until the user chooses to disable that feature) by long presses on the left and right keys. When

you are viewing a particular unit simply adjust with the keys and this setting will be remembered any time that

unit is selected in any calibration range, or a TEDs device is connected showing that unit. Decimal places can be

set from zero to seven. The resolution is disabled by default and is unwieldy to allow changing via the keypad or

menu system.

Resolution is stored against each Calibration Range (Or in the case of a TEDS device, per device) and is set in the

base calibrated units for that range at the factory. For the chosen display units resolution snaps to the nearest

appropriate 1,2 or 5 multiple in that unit. i.e.( .0001, .001, .01, .1, 1, 10, 100, .0002, .002, .02, .2, 2, 20, 200, .0005,

.005, .05, .5, 5, 50, 500.)

This selection works across all display modes.

TEDS (Transducer Electronic Data Sheet)

"Plug and play sensor hardware and software make configuring a smart TEDS sensor as easy as plugging a mouse

into a PC. The technology has greatly improved efficiency and productivity by completely eliminating manual

sensor configuration."

Basic concept

TEDS is at the heart of the universally accepted IEEE 1451.4 standard for delivering Plug and Play capabilities to

analogue measurement and test instruments. In essence, information in a Transducer Electronic Data Sheet

provides interfacing devices with the critical sensor calibration information in order to perform accurate and

precise measurements every time.

TEDS works in a similar way in which USB computer peripherals immediately work as they are connected. TEDS

enabled equipment maybe swapped and changed without recalibration, saving time and money.

TEDS holds information such as a sensor manufacturer, model and serial numbers, and more importantly all the

calibration settings determined by the manufacturer.

How it works

Plug and play is a data acquisition technology that can simplify the configuration of automated measuring

systems by making a sensor’s unique identification data available electronically. As implemented according to

IEEE 1451.4, data in the form of a transducer electronic data sheet (TEDS) is burned on an electrically erasable

programmable read-only memory (EEPROM) chip located on the sensor, so when a properly adapted signal

conditioner interrogates the sensor, it can interpret the self-identification data. This technology provides a great

benefit by eliminating the need for paper calibration sheets. And because all sensors produced according to the

standard will carry the same basic identically formatted self-identification information, you will be able to mix and

match sensors and applicable signal conditioners across manufacturers.

Advantages

Plug and play sensors are revolutionizing measurement and automation. With Transducer Electronic Data Sheets

(TEDS), your data acquisition system can detect and automatically configure sensors. This technology provides:

•

Reduced configuration time by eliminating manual data entry

•

Better sensor tracking by storing data sheets electronically

•

Improved accuracy by providing detailed calibration information

•

Simplified asset management by eliminating paper data sheets

•

Reliable sensor location by identifying individual sensors electronically

9325-NU Specifics

All standard TEDS devices contain a basic 2-point calibration. TEDS devices can also optionally hold more than

one extended calibration table; template ID=40 (multi-point calibration) or template ID=41 (polynomial

calibration). When you first connect a new TEDS device to the 9325-NU a message will be displayed stating that a

new TEDS device has been detected and that default settings have been used.

The first detected, valid calibration table from the TEDS device will be selected.

The user can select an alternative calibration table from the menu or Toolkit and this selection will be

remembered and the table will be re-selected next time the device is plugged in.

The 9325-NU will remember the last twenty connected TEDS devices so will automatically select the most

recently used calibration table and will re-use the User Experience parameters such as Units and tare values.

There is also an option to ignore TEDS on specific devices so that the 9325-NU Calibration Ranges can be used

instead of any Calibration Tables held in the connected TEDS device.

In this case the User Experience parameters will be used from the selected Calibration Range. i.e. The device will

act as if there is no TEDS chip until the user re-enables TEDS for this device. When a TEDS disabled device is

connected again it will automatically switch to the last used 9325-NU Calibration Range.

Extended TEDS Calibration Options

The 9325-NU supports up to five extended TEDS calibration tables in addition to the standard 2-point

calibration. These can be any combination of template ID=40 (multi-point calibration) or template ID=41

(polynomial calibration). This could be used to provide multiple calibrations for the transducer, for example high

range, low range, tension & compression.

Typically, a TEDS-enabled transducer would be supplied with one additional calibration template. The default

behavior is to select the first calibration template, or the standard 2-point if a calibration template is not found.

The user can cycle between all the available calibrations unless this feature has been restricted.

The TEDS standard allows very large or complex calibration templates to be defined. For practical reasons the

9325-NU imposes restrictions on the size and complexity that is allowed.

Multi-Point Calibration (template ID=40)

•

Maximum calibration points = 10

Polynomial Calibration (template ID=41)

•

Maximum number of segments = 1

•

Maximum number of coefficients = 10 (10th order polynomial)

A 4 Kbit (or larger) device is recommended where additional TEDS calibration templates are

to be included.

User Operation

Keypad

The keypad has some functionality that is fixed and some that can be configured and some that changes

depending on what is on the LCD display. The handheld can optionally sound a beep when keys are pressed.

Key

Function

The top right key doubles as the power key. Hold this for

approximately two seconds to turn on or off the handheld.

The three keys along the top of the keypad are soft keys and relate

to the three descriptions shown directly above them on the LCD

display. The action of these keys will depend on what is currently

being viewed.

The navigation keys are used for various purposes such as selecting

the current calibration range, selecting the current display,

navigating the menu system or editing string and numeric values.

The OK key is used to open the menu (If that has been allowed in

the configuration) and to select menu items and complete editing

sessions.

Later we will explain how to use the keys to navigate the menu

system.

When not in a menu the Up/Down keys can perform one of a few

user definable functions but the default is to cycle through all

available calibration ranges.

If a TEDS device is attached then these keys will cycle through any

valid Calibration Tables held in the device. If There is no TEDS device

(or manual override for that particular TEDS device has been set)

then the keys will cycle through the internal device Calibration

Ranges.

In both the menu and the toolkit the user may also select an action

for a long press. A long press is where the key is held down for over

a second before being released.
