This configurable transmitter offers outstanding reliability, accuracy and long-term stability and can be used in critical processes in all industries. It not only transmits digitally converted signals from resistance thermometers (RTD) and thermocouples (TC), but can also transmit resistance and voltage signals using the PROFIBUS® PA communication protocol. Sensor monitoring increases the effectiveness of the measuring point. Diagnostic information complies with NAMUR NE 107. Measuring accuracy is optimized by sensor-transmitter matching.
Advantages
Simple and standardized communication using the PROFIBUS® PA Profile 3.02 protocol.
Meets electromagnetic compatibility (EMC) requirements in accordance with NAMUR NE 21; the temperature transmitter with digital signal processing also complies with the NAMUR-recommended NE 89 standard.
Explosion-proof design based on FISCO/FNICO conformity requirements, in accordance with IEC 600079-27.
International approvals such as FM IS, NI, CSA IS, NI as well as ATEX Ex ia, Ex nA (Ex NL) ensure safe operation in hazardous locations.
High-precision measurement based on sensor-transmitter matching.
Sensor monitoring and instrument hardware fault detection for reliable operation.
Optional spring-loaded terminals for fast wiring without additional tools.
