Senix ToughSonic®  CHEM 20 Level Sensor

Senix ToughSonic® CHEM 20 Level Sensor

14 January 2019
Liquids or Solids in Chemically Aggressive Environments

Senix: CHEM series sensor 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.


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!

PC Setup Power

Use SenixVIEW software (see separate data sheet) to adjust all sensor features. You can view, analyze or log data to optimize your application. Disconnect and the sensor retains the setup.

Copy without Calibration

Application setups can be saved for future recall. From a single sensor inventory part you can quickly clone sensors, without recalibration, for any number of different field installations.

Multiple Options

In addition to the model's serial data interface there are five simultaneous outputs, fully configurable with SenixVIEW.

Analog Outputs (3)

These include voltage (0-10 VDC) and two current loops (4-20 mA sinking and sourcing). Both out- put types have user-selectable voltage/current ranges and end- points for best resolution. Easily invert the analog output slope.

Switches (2)

Two switches are SenixVIEW configurable as "PNP" or "NPN" type (sourcing or sinking). Each has adjustable set point, hysteresis, window, initial conditions, ON delay, OFF delay and loss of target response to easily create controls and alarms!
