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 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.
