The I-Tec Mini Series is a range of miniature non-contact infrared temperature sensors
with separate electronics modules.
All models have an adjustable emissivity setting and are capable of measuring a wide
variety of target materials, including food, paper, textiles, plastics, leather, tobacco,
pharmaceuticals, chemicals, ruMBer, coal and asphalt.
The optional touch screen interface provides temperature indication, alarms, sensor
configuration and data logging to MicroSD Card. The optional high-temperature
sensing head may be used in ambient temperatures of up to 180°C without cooling.
The low-noise cable on high ambient temperature models is resistant to interference
from movement, so it is ideal for mounting on moving objects such as robot arms.
A choice of optics are available to measure small or large targets at short or long
distances, and there is a choice of 4-20 mA, RS485 Modbus and alarm relay outputs.

FIELD OF VIEW
SENSING HEAD OPERATING TEMPERATURE RANGE
-MT 0°C to 60°C
-HT 0°C to 180°C
The high ambient temperature sensing head on -HT models is capable of withstanding temperatures
of up to 180°C without cooling. It is available with 20:1 optics.
There is no need to supply cooling air or water, and the miniature sensing head is much smaller than
bulky, cooled sensors.

EMISSIVITY ADJUSTMENT (-I MODELS)
The emissivity setting on I-Tec Mini -I models may be adjusted via two rotary switches inside the
electronics box. To adjust the emissivity setting:
Set the left switch to the first digit after the decimal point (0.1).
Set the right switch to the second digit after the decimal point (0.01).
To enter an emissivity setting of 1.00, set both switches to 0.
The minimum emissivity setting is 0.2. If a lower emissivity setting is selected, the sensor will default
to an emissivity setting of 0.95.
For example:
Left switch Right switch Emissivity setting
6 3 0.63
0 0 1.00
TOUCH SCREEN (-IT AND -MBT MODELS)
The optional backlit touch screen interface mounted in the lid of the electronics module provides a
large, bright display of the measured temperature, as well as options for full configuration of the
sensor. The graph view shows the history of the measured temperature.
In alarm conditions, the display changes colour to provide an immediate and obvious alarm
indication. Alarm modes and levels can be configured via the touch screen.

the power is cycled unless a battery is tted.
Output Processing
Averaging
Period
Hold Mode
Hold Period
Set the time, in seconds, over which the measured temperature is averaged.
Note: averaging prevents the sensor from following rapid temperature
changes. Minimum: 0 (no averaging). Maximum: 60.
Peak
The sensor holds the maximum temperature steady for the Hold Period.
After this, the sensor responds normally. If the sensor detects a higher
temperature, it holds this temperature steady for the Hold Period.
Valley
Similar to Peak Hold mode except that the sensor outputs the minimum
detected temperature steady for the Hold Period.
Off
Disables hold processing.
Set the time, in seconds, for the sensor to hold the temperature as above.
Minimum: 0 (no hold processing). Maximum: 1200.
