TSF40 Series Compact internal fitting with integral thermistor output TM Compact design Reliable reed switch contacts Available in Nylon, Polypropylene or PPS WRAS approval 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°.
