3 Product description

3.1 Product design

Prothermo NMT532 is a multi-spot Pt100 average thermometer combined with a local

HART signal converter to meet the demand of temperature measurement for inventory

control applications. NMT532 consists of Max. 6 temperature elements which have

different length with fixed (2m or 3m) interval. It is best suited connected to Proservo

NMS5, NMS8x, or Endress+Hauser Micropilot S-series radars and the Tank Side Monitor

NRF590. Mounted on the tank top, NMT532 provides temperature information on the two

wire, intrinsically safe (i.s.) powered local HART loop.
