PRO AUTOCAL: Calibration Without Opening the Unit

This capacitance sensor allows for simple, automatic calibration using a special magnet. No need to remove the unit cover!

Want a capacitance probe that sets up fast? Temperature-stable calibration and external testing can be performed in just minutes.

Get unsurpassed 0.5 pF sensitivity and fail-safe performance with the PRO AUTOCAL. Plus, an adjustable time delay of up to 10 seconds allows for settling of material--virtually eliminating false alarms.

What else you get with PRO AUTOCAL:

  • PRO-Shield compensates for material buildup to guard against false readings
  • Operates below RF range, always free from RF interference
  • Switch selectable high/low fail-safe safeguards from failures
  • Delrin or Teflon sleeved, bare, food grade, flush mount, or flexible probes
  • Visual LED indicates sensor status of uncovered, covered, or power failure

How and where to use PRO AUTOCAL:

  • As a point level detection and process control for solid, liquids, or slurries 
  • Aggressive materials such as coal or fly ash; power, mining, and foundries
  • Processing of plastics, chemicals, foodstuffs, or pharmaceuticals
  • Milling operations processing feed, grain, wood, or paper
