Floating Oil Thickness Monitor

Featured Product from Arjay Engineering Ltd.


Continuous monitoring of separated oil thickness on a water surface

The 4100-HCF monitors a floating sensor on the water surface to indicate the thickness of separated oil. An LCD display of the thickness, analog output and relay alarms are standard.

The 4100-HCF float sensor monitors the capacitance field of the water surface.

As the oil accumulates on the surface, the sensor capacitance changes. This interface signal is used to provide outputs, displays and relay control.

Features and Benefits:

  • No moving parts
  • Remote electronics via standard twisted pair
  • All set-up, calibration and diagnostics is at the control panel
  • All control wiring and interface is at the control panel
  • HF capacitance technology does not require routine cleaning
  • Touch screen interface for easy set-up and user interface
  • Sump view display for ease of reading
  • Trend display of hour, day or month increments
  • Single point calibration
  • Relays for valve control, alarms and pump run-time
  • Unique capacitance approach eliminates routine cleaning
  • Control and interface panel mounts safely away from the process

What is Capacitance?

Capacitance Monitors
Capacitance monitors and probes can be used for a variety of applications to monitor for product characteristics and process changes.
For reliable, continuous monitoring of solids and liquids, choose Arjay Engineering as your trusted capacitance monitor source. Our unique system effectively monitors the dielectric of solids and liquids for concentration, moisture content, blending, quality, changes, and more. Any changes to the overall dielectric can be tracked for process control and trends. Although ideal for overall monitoring and trending of process conditions our innovative capacitance monitors and probes can be used for a variety of applications. With over 40 years of experience in the industry, we strive to make our products as user friendly as possible. That’s why all of our capacitance instruments have easy calibration and control set-up; you’ll have your equipment up and running in no time. The user interface makes it easier than ever before to monitor your liquids and solids. For more detailed specifications on our versatile capacitance controls, contact us at 905-829-2418.
