Series Pressure Sensor

Instruction Sheet

Thank you very much for choosing Delta DPB series pressure sensor. Please read this instruction sheet carefully before using your DPB.

Keep this instruction sheet handy for quick reference.

Warning

DANGER! CAUTION! ELECTRIC SHOCK!

DPB is a pressure measurement device. DO NOT use it out of its specification. Improper pressure or incorrect wiring may

cause series injuries on staff or damages on other devices.

1. Keep away from high-voltage and high-frequency environment during the installation in case of interference. Prevent using the device in

premises which contain:

(a) dust or corrosive gas; (b) high humidity and high radiation; (c) shock and vibration.

2. DPB can only be used for air pressure measurement and should avoid corrosive, inflammable or toxic gas measurement.

3. Make sure the power supply is switched off when installing or dismounting DPB and the pressure source stops its action in case harms

occur on human body and properties.

4. DO use parts compatible to the specification of the pressure pore for connection to avoid mistaken measurement or safety problems.

5. Before switching on the power supply, check the signal connection, e.g. the input voltage and polarity. Voltage that is too high may cause

damages on DPB.

6. DO use dry cloth and DO NOT use acid or alkaline liquid to clean the device.

How to Set up Parameters

Switching modes: DPB will be in the “Measuring Mode” when it is switched on, displaying PV and SV. Press for more than 2 seconds

in this mode to switch to the “Quick Setup Mode”. Press for more than 4 seconds in the “measuring mode” to switch to “Advanced

Setup Mode”. Press in the “Quick Setup Mode” or “Advanced Setup Mode” to return to the “Measuring Mode”.

Setting up parameters: In the three modes, press once to select the parameter to set up. When you find the parameter to be set up

or modify, use to modify the setting.

Initial Setting

1. Units: DPB provides many units for users, including kPa, kgf/cm2, bar, psi, mmHg and inchHg. In the easy mode, you can press and

find to set the unit to the desired one.

2. Output status: You can set up 2 output status in DPB, N.O. (normally open) and N.C. (normally closed). In the easy mode, you can press

and fine to set up the output status for OUT1 and OUT2.

3. Response time: Referring to the time required for the pressure to reach output status. For example, “50” refers to once the pressure has

reached the output status, it has to last for 50ms before the output starts to operate. In the easy mode, press and find .

Use to set up the response time.

Output Mode Setting

There are 3 output modes in DPB: Easy, Hysteresis and Window

1. Easy Mode: Set up pressure P. When the pressure measured is bigger than (P + dP), the output will be ON. When the pressure measured

is smaller than P, the output will be OFF. (See Figure 1: Output in Easy Mode)

In the “Measuring Mode”, press and find (OUT1) and (OUT2). Use to set up P value.

In the “Advanced Setup Mode”, press and find . Use to set up “dP” value.

[Figure 1: Output in Easy Mode]

2. Hysteresis Mode: Set up pressure Hi/Lo. When the pressure measured is bigger than the Hi value, the output will be ON. When the

pressure measured is smaller than the Lo value, the output will be OFF. (See Figure 2: Output in Hysteresis Mode)

In the “Measuring Mode”, press and find (OUT1 Hi), (OUT1 Lo), (OUT2 Hi) and (OUT2

Lo). Use to set up Hi/Lo values.

[Figure 2: Output in Hysteresis Mode]

3. Window Mode: Set up pressure Hi/Lo. When the pressure measured is bigger than Hi or smaller than Lo, the output will be OFF. When the

pressure measured is bigger than Lo and smaller than Hi, the output will be ON. (See Figure 3: Output in Window Mode)

In the “Measuring Mode”, press and find (OUT1 Hi), (OUT1 Lo), (OUT2 Hi) and (OUT2

Lo). Use to set up Hi/Lo values.

In the “Advanced Setup Mode”, press and find . Use to set up “dP” value.

[Figure 3: Output in Window Mode]

Note: Supposed the output is ON and the output status is set to N.O. (normally open), the output will then be off. If the output status is set

to N.C (normally closed), the output will then be on. Supposed the output is OFF and the output status is set to N.O., the output will then be on.

If the output status is set to N.C., the output will then be off.

Zero Returning

In the "Measuring Mode”, press together, and you will see . The zero returning will start. Release the keys to end the zero

returning.

Key Locking Function

Lock On: Press and together for 2 seconds until is displayed. You will then see the display of pressure value (PV) and

set value (SV).

Lock Off: Press and together for 2 seconds until is displayed. You will then see the display of pressure value (PV) and

set value (SV).

Lock Display: Press any key in the key locking mode, and you will see the display of pressure value (PV) and (SV). Release the

key, and the PV and SV will return to original values.

Switching Colors

In DPB, different output statuses can have different display colors. The output statuses for DPB are “OUT1”, “OUT2”, ”OUT1 and OUT2”,

“OUT1 or OUT2”. See below explanations for how to set:

1. Setting up output status: In the “Measuring Mode”, press for more than 4 seconds and release the key after you see . You

are now in the “Advanced Setup Mode”. Press for 4 times and find the switching color referencing items (see Advanced Setup Mode

chart). Use to select the referencing item you'd like.

2. Switching colors: In the “Measuring Mode”, press for more than 2 seconds to enter the “Quick Setup Mode”. Press for 4 times

and find the parameter for setting up colors (see Quick Setup Mode chart). Use to select the color you’d like.

Note: “OUT1 and OUT2” will be ON only when both OUT1 and OUT2 are ON; otherwise, it will be OFF. “OUT1 or OUT2” will be OFF only

when both OUT1 and OUT2 are OFF; otherwise, it will be ON.

Code

DPB offers codes for the user to set up. In the “Measuring Mode”, press for more than 4 seconds and release the key after you see

. You are now in the “Advanced Setup Mode”. Press for 5 times to find the parameter to set up codes (see Advanced Setup Mode

chart). displays in turn.
