RSF20 low level switch for boiling water TM The RSF20 is designed to eliminate the problems associated with limescale build up around the pivot point on a conventional float switch. Low level switch position This particular series is primarily for applications where a low level condition has to be monitored, in a system where the liquid is usually maintained at a high level, or where a wider differential is required between the opening and closing levels. WRAS approved for use in hot and cold water The extended drop float actuator allows the switch housing and float pivots to be located above the surface of the liquid, while the excess buoyancy of the float chamber itself ensures that it remains buoyant, even when scale builds up on the float chamber. Typical applications include wall kettles and hot vending machines. Hot/boiling water High buoyancy float Many variants are UL recognised components. File number E171218 Technical Specification Material RSF26 Polyphenylene Sulphide (PPS) Colour Grey Temp. Range °C °F Min. Fluid S.G. Must Close Level (S.G.=1 Must Open Level (S.G.=1) -10 / +120* +14 / +248* 0.75 140mm 110mm *Maximum temperature requires ETFE cable to be specified. The switch action is closed when the level is low (float down), and opens as the liquid level rises. Electrical Specification Contact Form Switching Power Max. VA Switching Voltage AC Max.
