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
