The TSF70 series is a compact external

fitting device, with a high specification

thermistor so capable of sensing both

liquid level and temperature.

Mounting of this series is with the use of a

compression seal, so does not require

access to the inside of the tank.

Typical applications include vending

machines, commercial washing machines

and evaporator units.

They are manufactured in a variety of

materials with a choice of gasket

materials, to suit most commonly used

liquids.

The switch action may be reversed by

rotating the device through 180º.
