MRtd01 Dual temperature sensor converter for PT100




  • two independent converters for PT100 sensors
  • three-wire sensor connection
  • linearized output
  • voltage or current output
  • possibility to adjust the temperature range
  • detection of unconnected or defective sensor
  • wide supply voltage range 1030 VDC


Description

MRtd01 is dual converter for connecting PT100 RTDs. Temperature sensors are connected in three wires. The converter allows the detection of unconnected or deffective sensor. The output of the transmitter can be either current or voltage.

The temperature range and offset of the converter are preset from the factory, but can be adjusted to a lesser extent. In the working range the converter is almost linear, the required absolute accuracy is ensured by calibration.

The converter has a built-in current source to power the connected resistive sensor.

The module is mounted in a plastic box for DIN rail mounting.
