Prothermo NMT532

Prothermo NMT532 ©Endress+Hauser

High precision average temperature measurement

The Prothermo NMT532 is an intrinsically safe multi-signal converter with precision average temperature sensor for inventory control. It is a highly capable solution for a variety of tank gauging applications and provides constant average temperature data via HART communication. For custody transfer and accurate inventory measurement, it is best suited connected to Proservo NMS5 or Tank Side Monitor NRF590 with Micropilot radar tank gauge.
