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.
