5802
Compact RTD temperature transmitter
- RTD or Ohm input
- Accuracy: Better than 0.1% of selected range
- 2- / 3-wire RTD connection
- Programmable sensor error value
- Output 4...20 mA, with or without M12 connector
Application
- Linearized temperature measurement with Pt100...Pt1000, or Ni100...Ni1000 sensor.
- Conversion of linear resistance variation to a standard analog current signal.
Technical characteristics
- Within a few seconds the user can program PR5802 to measure temperatures within all RTD ranges defined by the norms.
- The RTD and resistance inputs have cable compensation for 3-wire connection.
Mounting / installation
- For tube mounting, e.g. M18 barrel housing or customer specific housing.
- The unit is tested with an M12 connector, mounted in a steel housing and molded with Silgel 612 silicone molding compound. This is PR electronics' recommended method to comply with specifications and EMC data.
