PTC thermistor type level sensors for outdoor tanks according TRbF 511.

GWG 23 – Ro

This PTC thermistor type level sensor is equipped with a height adjustable probe. It features a G1 brass screw fitting and is pressureand vacuum tight (1 bar). Tube fitting made of yellow, high grade impact resistant plastic with strong chain and flange gasket.

The version with grey fitting is impact resistant and equipped with a tie instead of the chain, without flange gasket. The number after the type designation indicates the length of the GWG level sensor. When selecting, please check to see that the fitting is as close as possible under the access chamber cover – the distance should not be less than 20 mm and not more than 300 mm..
