4-20 mA Current Transmitter for Resistance Input in Ohms
Key Features
  • Five precalibrated resistance input ranges from 20.000 Ω to 200.00 kΩ
  • 1 mΩ resolution on 20 Ω scale
  • Exceptional accuracy and repeatability
  • 2, 3 or 4-wire connection with lead resistance compensation
  • Isolated 4-20 mA, 0-20 mA or 0-10 Vdc analog output (jumper selectable)
  • Output resolution: 0.0015% of span (16 bits)
QA Application with Relays in Passband Mode
Deviation mode relay operation for QA testing of resistance A deviation limit (50 mΩ in this example) is set up around both sides of a setpoint. The relay closes (or opens) when the reading falls within the deviation band, and opens (or closes) when the reading falls outside of this band. This mode sets up a passband around the setpoint and can be used for contact resistance testing in a production environment.
