Prothermo NMT532 Product description
Hauser 11
Item Details
Protection class IP66/68 NEMA4X/6P:housing with temperature probe
Electromagnetic
compatibility When installing the probes to metal or concrete tanks and when using a coax probe:
• Interference emission according to EN 61326, Electrical Equipment Class B
• Interference immunity according to EN 61326, Annex A (Industrial)
Process temperature
range Temperature probe: –20 to 100 °C (–4 to 212 °F)
Process pressure Atmospheric pressure (absolute pressure 1 bar, 100 kPa, 14.5 psi)

• Pressure tank: If the pressure inside the tank exceeds the process pressure shown above, install a stilling well
(protective tube) without holes or slits in the NMT532 to protect the probe from the pressure.
• Static pressure: Because NMT532 has undergone an airtightness test at an absolute pressure of 7 bar, it can withstand
static pressure head in the 50 m (164 ft) range in petroleum/chemical product applications.
