ToughSonic CHEM 35 Level Sensor
Liquids or Solids in Chemically Aggressive Environments
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 pro- cessing, water management and high/low level alarms.
Non-Contact Ultrasonic Distance & Level Measurement
Features
Level Measurements
• Long or short measurements
• Unaffected by optical factors like color and transparency
• Computer (PC) software allows remote adjustment
Packaging & Performance
• Durable housing for long life
• Bottom and top thread mounts
• Short & overload protected I/O
• Adjustable filters compensate for tank mixers or turbulence
• Temperature compensation for improved accuracy
• Adjustable sensitivity
Free Functionality
Use adjustable interface features like switch hysteresis and time delays to build complete solutions such as pump controls to maintain level. Save cost by eliminating PLCs, delay circuits and time
delay relays!
