Product Specification

ToughSonic CHEM 35 Level Sensor
Liquids or Solids in Chemically Aggressive Environments

The ToughSonic CHEM 35 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. The maximum range of 35 feet (10.7 meters) is the longest range model in the ToughSonic CHEM sensor family.

The ToughSonic CHEM 35 is sealed in a PVDF (Kynar) housing. It is fully submersible, chemical resistant and shock resistant. It has a potted-in 9-wire cable that connects up to five simultaneous analog and/or switch outputs plus a serial interface. It is fully configurable with SenixVIEW configuration and analysis software.

Please see the full line of ToughSonic and ToughSonic CHEM sensors for alternative ranges, sizes and housing materials.
