PRO AUTO-CAL Capacitance
Probes 
Simple, Automatic Calibration
without Opening the Device
Pro Auto-Cal offers simple and automatic calibration and
external testing without having to remove the cover of the
unit. Calibration takes just seconds and is performed with
the use of a special magnet. This unit also allows for the
simulation of either a covered or uncovered condition without
accessing the probe assembly or the electronics and unsurpassed
sensitivity of 0.5 pF for enhanced accuracy. A visual LED
on the top of the housing indicates sensor status such as
uncovered, covered or power failure.
Operating below the RF range, Pro Auto-Cal will not interfere
with two-way radios or other plant equipment operating within
radio frequency. It offers fail-safe performance –
alerting users to power failures – and a Pro-Shield
feature which compensates for material build-up to protect
again false readings. Other benefits include temperature-stable
calibration and an adjustable time delay of up to 10 seconds
to allow for settling of material. Pro Auto-Cal offers optional
sensing probes including Delrin or Teflon-sleeved, bare,
food grade, or flush mount, plus a variety of solid and
flexible extensions making it suitable for many applications.
