LT-20 Dual-Function Level & Temperature Switch

**This product is currently discontinued.

HiTECH’s LT-20 Dual-Function Level & Temperature Switch operates using an ultrasonic GAP level sensing technique. The electronic control unit, either integral or remote to the sensor, generates a signal that indicates the presence of liquid as well as when the correct liquid temperature (40 0F) is present. Additionally, an integral temperature sensor monitors the liquid’s temperature. When the liquid is present and the temperature is above 40 0F, the relay stays at a de-energized state. If liquid is present and the temperature is below 40 ⁰F, the relay energizes and stays energized until the temperature reaches 40 ⁰F + 2 ⁰F or the liquid level falls below the sensing point. HiTECH’s model LT-20 Dual-Function Level & Temperature Switch provides very reliable performance with virtually any liquid, regardless of the viscosity. The Dual-Function Level & Temperature Switch is ideal for application on Refrigeration Automation, Freon Testing, Supply Line Automation, Corrosive Liquids, Pipelines, Equipment Reservoirs and various OEM applications.
