Successful ultrasonic sensors resistant to chemicals thanks to Kalrez® seals

SNT Sensortechnik AG: could equip lately several renowned customers in the chemicals field with the new UPR-A CP ultrasonic sensor. The sensors are designed for use in aggressive environments. The very high resistance is based on PVDF and PTFE.

One possible application is the level measurement of acids and alkalis in vessels up to 1.5m height. The basic sensor is a type UPR-A 1500. The face exposed to the medium is made of PVDF. The outstanding feature of this sensor is the fact that the ultrasonic transducer is completely enclosed with a special PTFE film which transmits the ultrasonic waves. Another specialty are the internal seals made of the super-resistant elastomer Kalrez ®.

The sensor is available with analog or switching output. All other settings are programmable by the customer. Including the adjustment of different sound lobe sizes.
