The temperature transmitter converts the field resistance temperature detector (RTD) or thermocouple (TC) signal into a standard current signal of 4 to 20 mA for control and remote transmission. It supplies secondary instruments such as indication alarms, recorders, regulators, and DCS for measurement, indication, and process regulation.
Features
· Isolation type temperature transmitter: input/output signal isola tion, meeting 500V electrical isolation (input/output).
· High-performance precision conversion: stable and reliable, long service life.
· Internal/external cold junction compensation can be selected, with linear calibration and testing of various signal types.
· Fast response: the response time is within 500ms.
· It has strong anti-electromagnetic and radio frequency interference capabilities, and complies with IEC/EN61326 standards.
· Diagnosic function: self-fault diagnosis, sensor disconnection short circuit diagnosis, variable upper and lower limit detection and other diagnosis.
· Supports HART5/7 (optional). Through the HART interface, the temperature transmitter module can be configured and maintained for specific applications.
· Modular glue-filled packaging treatment, moisture-proof, anti-vibration, large temperature range, suitable for a vari ety of complex working conditions.
· Intrinsic safety explosion-proof and dust explosion-proof: suitable for explosive site installation and use.
