With G1 process connection and contact-free measurement, Pressure rated Ultrasonic Sensors can be used for fill level measurement applications under normal pressure or in tanks and containers with overpressure of up to 6 bar. Fill level measurement can be carried out concurrently with overflow protection through combination of switching outputs and analog outputs. Stainless steel housings are resistant to chemicals, and PTFE membrane protects sensor from aggressive fluids and chemicals.
