The TSF40 series is a development of the

established RSF40 series range of liquid level

sensors. Incorporating a high specification

thermistor, this device is now capable of sensing

fluid level and temperature

Typical applications include vending machines,

steam baths, saunas 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 180°.
