RTD

4-wire connection

2-wire Transmitters

MESO-H/-HX are smart and universal 2-wire in-head transmitters for tem­perature and other measurement applications. MESO-H/-HX are fully HART­compatible, with communication through the HART protocol.

• Utilizes HART Protocol for remote conguration and monitoring

• Communicates with HART Communicator or PC via modem

• Fully universal, linearized and isolated

• Accepts RTD, T/C, mV and Ω

• Sensor error correction

• Easy wiring, large center hole

• 50 point linearization – any sensor can be matched

• Consistent sensor break function

• Full access to all features while in operation

• Low sensor isolation detection

• MEPRO, easy-to-use Windows conguration software

• Integrated in Emerson AMS and Siemens PDM systems
