DT1012 temperature resistance potentiometer transmitter-type designation

Product description

PT100 / Pt1000 temperature sensors or linear resistance / potentiometer can be connected to the input of the DT1012… Temperature / resistance / potentiometer transmitters.
The transmitter feature complete 3-way isolation: the input the output and the power supply circuits are isolated of each other using state-of-the-art planar transformer design.
The transmitter has two outputs *:
• 0 – 20 mA / 4 – 20 mA current, or
• 0 – 5 V / 0 – 10 V / 2 – 10 V voltage
* only one output can be used at the same time
In the case of a Pt 100 / Pt 1000 temperature sensor, the output signal is proportional to the measured temperature, in the case of resistance to the measured resistance, in the case of a potentiometer, with the position of the potentiometer.
Sensors can be connected to the input with 2 / 3 / 4 wires. In the case of a 3/4-wire connection, the connecting wires resistance does not affect the measurement.
The transmitter can be configured via the USB port.
The characteristics that can be specified are:
input signal source, 2 / 3 / 4 wire measurement mode, measurement range, input signal averaging, output selection, output signal range, etc.
If a calibrated Pt100 or Pt1000 sensor is used, the calibration values can be downloaded to the transmitter.
The configuration software and the USB cable are included with the device.
The configuration program can also be downloaded from the company’s website (www.datcon.hu).
The transmission characteristics of the transducer are exceptionally good: the error of the output signal < ±0.1 °C, the temperature coefficient is < ±20 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: DIN rail housing, plugable terminal blocks with screw connection, width: 12.5 mm.
