Universal HART-compatible 2-wire Transmitter

MESO-L is a smart and universal 2-wire transmitter for temperature and other measurement applications. MESO-L is fully HART-compatible, with communication through the HART protocol.

  • 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
  • 50 point linearization – any sensor can be matched
  • Consistent sensor break function
  • Simplified loop check-up with calibration output
  • 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
