Durable metal-housed optical liquid level sensors provide a single point, N-type, switched sensor output for rugged, high-pressure applications. Ideal for:
Aggressive environments
Sealed, compact design for HVAC and other industrial applications
Capable of withstanding high and low temperatures and mechanical shock and pressures up to 5000 psi (345 bar)
An infrared LED and phototransistor ensure dependable optical coupling when the sensor is in air to prevent false readings. When the sensing tip is immersed in liquid, the phototransistor senses the liquid to switch the output state. Low power signal, ideal for micro-controllers when needing to detect the absence or presence of most any non-coating liquid
Minimum order: 25 pcs
