The INOR MESO-H temperature transmitter is a smart and universal 2-wire in-head transmitter for temperature and other measurement applications.

The Inor MESO-HX temperature transmitter is the Intrinsically Safe version for use in EX applications.

The INOR MESO-H/HX temperature transmitters are both fully HART ® compatible, with communication via HART ® protocol, directly on the 4-20mA output loop, by using either a general hand-held HART ® Communicator or the INOR PC software, MEPRO 2.

MEPRO 2 is a Windows ® based and user friendly software, which facilitates the access to and use of functions like transmitter configuration, documentation, monitoring, and calibration.

The INOR MESO-H/HX temperature transmitters are both designed for applications with high demands on accuracy, also under severe operating conditions. To reach these demands, the following factors are essential:

  • Linearity and calibration errors: The combination of an efficient linearization function and the use of quality components and precision calibration equipment reduce these errors to ±0.1% of span.
  • Ambient temperature influence: The INOR MESO-H temperature transmitter is compensated to reduce the ambient temperature influence to low levels.
  • High long-term stability: Internal "self calibration", by means of continuous adjustment of important parameters after comparison with accurate built-in references, contributes to a stability of ±0.1%/year.
