Description

Application
• Linearized temperature measurement with Pt100...Pt1000, Ni100...Ni1000, or TC sensor.
• Conversion of linear resistance variation to a standard analog current signal, for instance from valves or Ohmic level sensors.
• Amplification of a bipolar mV signal to a standard 4 to 20 mA current signal.
Technical Characteristics
• Within a few seconds the user can program PR5331A to measure temperatures within all ranges defined by the norms.
• The RTD and resistance inputs have cable compensation for 2/3 and 4-wire connection.
• A continuous check of vital stored data for safety reasons.

Can I program the output of the 4-20ma to equal 0 degrees F to 300 degrees F. &nbsp;i.e. &nbsp;4ma=0F and 20ma=300F with a 100ohm RTD 32-492F range.

Asked by: DWoody
You can scale the PT100 RTD to any values within the sensors range using the TXUN-KIT programming module sold as an accessory.
