The Prothermo NMT539 is an intelligent HART signal converter used together with an average temperature sensor and a water bottom interface probe. It measures the average temperature using precise multi-point Pt100 elements. The NMT539 provides stable average temperature data and water interface data via HART communication, making it a highly reliable solution. For custody transfer and high-precision inventory measurement, it is recommended to connect the NMS5 Proservo or use the tank-side indicator NRF 590 together with a Micropilot radar level meter.
Advantages
Intrinsically safe device that maximizes the safety of the electronic component settings.
Four different versions are available:
: 1) converter only; 2) converter with temperature sensor; 3) converter with water bottom sensor; 4) converter, temperature sensor and water bottom sensor.
The converter is compatible with numerous third-party temperature sensors.
Compatible with the user-friendly Endress+Hauser ToF (time-of-flight) tool
Various process connection types and cable entry specifications are available to meet the standards of different countries
