Datexel PC programmable two wire isolated universal transmitter - DAT4035

TC/RTD/… Input, Current Output, Highly Accurate, Made in Italy


The transmitter DAT 4035 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 standard active current signal, conversion of a voltage signal even coming from a potentiometer connected on its input.

Moreover, the DAT 4035 is able to measure and linearise the standard thermocouples with internal cold junction compensation.

The measured values are converted in a 4-20 mA current signal. The device guarantees high accuracy and performances stability both in time and in temperature.

The programming of the DAT 4035 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 linearise signal.

For Resistance and RTDs sensors it is possible to program the cable compensation with 3 or 4 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 terminals of the current signal on input side must be only connected to active current loop.

The 2000 Vac isolation between input and power supply/output eliminates the effects of all ground loops eventually existing and allows the use of the transmitter in heavy environmental conditions found in industrial applications.

It is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
