DT1022 temperature potentiometer resistance transmitter

Type designation

Product description

Almost all of the most commonly used temperature sensors in the industry can be connected to the
DT1022… Temperature / resistance / potentiometer transmitters:

Pt100, Pt1000 resistance thermometer sensors
E, J, K, N, R, S, T thermocouples
linear resistance / potentiometer transmitters
direct voltage sources

The device has two outputs *:

0 – 20 mA / 4 – 20 mA current
0 – 5 V / 0 – 10 V / 2 – 10 V voltage

* only one output can be used at the same time

The DT1022 provides 3 way isolation, i.e. the input, output and power supply are galvanically isolated from each other.
In the case of a Pt 100 / Pt 1000 temperature sensor and E, J, K, N, R, S, T thermocouples, the output signal is proportional to the measured temperature, in the case of resistance to the measured resistance, in the case of a potentiometer, to the position of the potentiometer.
Pt100 / Pt 1000 sensors can be connected to the input with 2 / 3 / 4 wires. In case of 3 / 4 wire connection, the resistance of the connecting wires does not affect the measurement.
When thermocouples are connected, cold junction compensation can be implemented in two ways:
in the case of an internal cold junction, the device measures the temperature of the thermocouple terminals, in the case of an external cold junction, a Pt100 or Pt1000 sensor can be used to measure the external cold junction temperature and compensates the thermal voltage of the thermocouple with these.
The devices are also suitable for measuring direct voltage in the range -100 mV to +100 mV.
Operating parameters can be set and downloaded via a USB port using a simple configuration program running on
a PC:

selection of input signal source and measurement arrangement
method of cold junction compensation
measurement range setting
input signal averaging
current / voltage output
output signal range selection, etc.

When using calibrated Pt100 / Pt1000, it is possible to enter the calibration values.
The configuration software and the USB connector are included with the device.
The measurement characteristics of the transducer are exceptionally good: the error of the output signal is < ±0.1 °C, temperature coefficient < ±25 ppm / °C typically.
The device can be ordered in two power supply versions:

DT1012.. types 24 VDC
DT1012.. PS types 230 V AC/DC

Design: 12.5 mm DIN rail housing with plugable terminal blocks with screw connection.
