TSF70 Series Compact External Mount with Temperature Sensing Compact design with temperature sensing Available in Nylon, Polypropylene or PPS 25VA & 100VA versions Many variants are UL recognised components File No. E171218 WRAS Approved versions Technical Specification Material 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. TSF73 Nylon TSF74 Polypropylene WRAS approved Colour Black Opaque Temp.
