TM
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°.
