Datexel RTD and Thermocouple Temperature Transmitter DAT1075

Highly Accurate, Current Output, Italian made

The transmitter DAT 1075 is able to execute many functions such as: measure and linearisation of the temperature characteristic of RTDs sensors, conversion of a linear resistance variation, conversion of a voltage signal even coming from a potentiometer connected on its input.

The measured values are converted in a 4÷20 mA current signal. Moreover, the DAT 1075 is able to measure and linearise the standard thermocouples with internal cold junction compensation. The device guarantees high accuracy and performances stability both in time and in temperature.

The programming of the DAT 1075 is made by a Personal Computer using the software PROSOFT, developed by DATEXEL, that runs under the operative system "WindowsTM ". By use of PROSOFT, it is possible to configure the transmitter to interface it with the most used sensors.

In case of sensors with a no-standard output characteristic, it is possible to execute, via software, a "Custom" linearisation (per step) to obtain an output linearised signal.
For Resistance and RTDs sensors it is possible to program the cable compensation with 3 wires; for Thermocouples it is possible to program the Cold Junction Compensation (CJC) as internal or external.

It is possible to set the minimum and maximum values of input and output ranges in any point of the scale, keeping the minimum span shown in the table below.
Moreover, it is available the option of alarm for signal interruption (burn-out) that allows to set the output value as high or low out of scale.

The DAT 1075 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
It is housed in a self-extinguish plastic enclosure suitable for DIN B in-head mounting.
Moreover (by proper mounting kit) it is possible to mount the DAT 1075 on DIN rail.

Series Information

“DAT1000 SERIES”: temperature transmitters for DIN B in-head mounting

The transmitters of the DAT1000 series can accept at their input signals coming from 2,3 or 4 wires Pt100, thermocouple and potentiometer sensors or voltage signals (mV).The devices provide a 4÷20 mA two wire current loop output signal.
The series is composed of devices with input configurable by PC with or without galvanic isolation. Moreover, it is available a version of the transmitters of the DAT1000 series developed for the use in potentially explosive atmospheres certified in according to the DIRECTIVE ATEX 94/9/EC. (see p. 24 to 26).
