Description
Conical Sensor, Pt100
Hygienic, without gasket
Compact mounting
Fast response time
High accuracy
Wide temperature ran ge
Acid-proof, stainless steel
The wetted parts of the conical sensor are in acid-proof stainless steel.
The sensor is available as a cable sensor with high-fl exible, 4-wire
silicone cable.
The conical sensor is ideal for measuring tem pe ra tu re in pipe systems
and tanks. The sensor mounting is hygienic and without gasket in a
male nipple part welded into the pipe or the tank wall.
