ADVANTAGES
- Class AA accuracy
- 4-20 mA programmable current output0-10 VDC programmable voltage output
- Robust 316 stainless steel design
- IP67 enclosure for harsh environments
- Fast response to temperature changes
- Compact and low mass sensor probe
- Optional solid-state setpoint relay for process control
- Dual sensor design
The TDM-1 series temperature transmitter is designed for gas and liquid measurement in a variety of industrial applications. Its modular compact design offers a unique combination of high measurement performance, flexible configuration and a robust stainless steel design.
Temperature sensor technology
Traditional temperature measurement is based on thermistor, thermocouple or RTD sensors. The TDM-1 is based on semiconductor diode junction sensor technology. The sensor technology offers high measurement accuracy and repeatability in combination with a fast response to temperature changes.
The novel dual sensor probe design offers two individually calibrated sensors for improved measurement stability and redundancy in critical applications.
