Product Specification

ToughSonic CHEM 20 Level Sensor
Liquids or Solids in Chemically Aggressive Environments

The ToughSonic CHEM 20 is designed for applications where corrosive liquids or gasses are present, but it is an excellent choice for benign environments as well. The maximum range of 20 feet (6.1 meters), it is the mid-range model in the ToughSonic CHEM sensor family.

The ToughSonic CHEM 20 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 whole line of ToughSonic and ToughSonic CHEM sensors for alternative ranges, sizes and housing materials.

Non-Contact Ultrasonic Distance & Level Measurement

LVL-300 Series Chemically Resistant Ultrasonic Level Sensor Features
