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.
Voltage
mV
• Utilizes HART Protocol for remote configuration and monitoring
• Communicates with HART Communicator or PC via modem
• Fully universal, linearized and isolated
• Accepts RTD, T/C, mV and ohm
• 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 configuration software
• Integrated in Emerson AMS and Siemens PDM systems
