R3 - thermistor sensor

Artnr: 1177
Rsknr: 5633516

Standard sensor for oil tanks above ground

Sensor for above-ground tanks containing fuel oil (eo1) and diesel as well as petrol.

The sensor's sensing element consists of a PTC-type thermistor. PTC = positive temperature coefficient, means that the thermistor, when it is passed through by an intrinsically safe current, increases its resistance at the same time as the temperature in the thermistor rises.

Since the thermistor can only reach its higher temperature when it is in air or gas, the amplifier, which is connected to the thermistor, can determine whether the thermistor is in air, gas or liquid.

The sensor is designed for use in the Ex-zone.

The sensor is delivered as standard with 5 m oil-resistant cable, connector, flange gasket and mounting screws.

R3 is mounted in a ½ ”socket or directly through the flange of the connection part on the roof or manhole cover.
