DescriptionThe L170 Series Compact Level Switches feature a Buna-N or stainless steel float for higher heat and pressure capabilities. Designed for low-cost, high-volume use, the L170 vertical switches are best suited in shallow and restricted tank spaces. Their durable brass and stainless steel construction also allow for installations in several harsh and corrosive environments. The L175 features a larger stainless float that will operate in fluids with specific gravities as low as 0.70. Alternatively, the L177 is equipped with a reinforced float that will withstand pressures up to 600 PSIG. All stainless steel L170 models are FDA compliant with food contact regulations and provide an ideal choice for use in food and beverage equipment.
Principles of OperationA hermetically-sealed reed switch is actuated by an internal magnet within the float. As the float rises and falls with the liquid level, the magnetic field passes the switch encapsulated within the stem and causes the contact to either open or close.
