TXUN ST 2 Wire Programmable Transmitter w Universal Input 12911
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.
• FM Approval Model Available (TXUN-FM)
• RTD, TC, &Omega , or mV Input
• Extremely High Measurement Accuracy
• 1.5 kVAC Galvanic Isolation
FM Certificate (TXUN-FM only)FM17US0013X
