Resistance Temperature Detector

Head mounting type multi temperature transmitter_R911 (with T900)

R911 (with T900)

Service intended

T900 series temperature transmitters are designed to fit into a standard molded terminal heads used on RTD and thermocouple assemblies to provide a 4-20 mA transmission signals. It is a cost effective solution for all temperature measuring process. It is accurate, durable and reliable. Numerous configurations for measurement in many deferent mediums are offered. Generally the transmitter produces a linear 4-20 mA output carried on a two-wire system. The transmitter is supplied factory calibrated, but also has zero and span potentiometers for a field adjustment.

Advantages ■ Two wire 4-20 mA current output signals
■ Universal input signals
   - RTD temperature sensor
   - T/C elements
   - mV, V, mA, DC signals
■Programmable function setting
  - Input signal type
  - Measuring range
  - Burnout Low/High setting
  - mA output offset
■ Excellent accuracy and a long term stability
■ Low cost effective
