The ToughSonic CHEM 35 ultrasonic sensor is designed for distance measurement applications where corrosive chemical liquids or gasses are present, but it is an excellent sensor for benign environments as well. With a maximum range of 35 feet (10.7 meters), it is the longest range member of the ToughSonic CHEM sensor family. The sensor is sealed in a PVDF (Kynar®) housing. It’s fully submersible, chemical resistant and shock resistant. The ToughSonic CHEM 35 has a permanently attached, potted-in-place 9-wire cable that allows up to six simultaneous serial, analog and/or switch outputs. It’s fully configurable with SenixVIEW configuration and analysis software.

CHEM series sensors and SenixVIEW software put the power of ultrasonics in your hands. You can quickly adjust, optimize, save and clone your applications quickly without calibration! These sensors are housed in a rugged, chemically inert PVDF sealed housing for long life. They mount above the material surface and measure distance downward without contact. Outputs respond to that measured distance. Applications include pump control, bulk inventory, batch processing, water management and high/low level alarms.
