Intrinsically safe device that maximizes the safety of the electronic circuit.
Compatible with the user-friendly ToF (time-of-flight) tool
Simple and economical
Small size, light weight
Reliable measurement, simple installation
Maintenance-free
Application
The Prothermo NMT532 consists of an intelligent HART signal converter and an average temperature sensor. For average temperature measurement, it measures precisely using multiple Pt100 elements (up to 6) at fixed intervals. Via HART communication, the NMT532 provides stable average temperature data and is the ideal solution for numerous tank farm measuring instrument applications.
Inventory measurement: connected to the tank-side indicator NRF 590, used together with a Micropilot radar level meter or the NMS5 Proservo.
