Light Scatter Technique

Featured Product from Arjay Engineering Ltd.

HydroSense 3420 PPM Oil in Water Alarm
The HydroSense 3420 continuously monitors a clean water sample for oil leaks.

The display, signal output, and alarm can be configured within the 0-100 ppm range. On-line alarm for oil presence in filtered effluent and cooling water

The HydroSense 3420 offers a low-cost approach to monitoring ppm concentrations of emulsified free oils in clean water. Combining many unique design features into a compact package makes this an ideal solution to monitoring for oil leaks in your water system.

The HydroSense 3420 uses a light scatter technique to respond to oil contamination in the water.
A slip stream approach directs a continuous sample flow through the HydroSense unit and back into the process stream. While it passes through the sample cell a controlled light source is directed into the water. The emulsified oils in the water will scatter the light toward the light sensors placed strategically around the cell. The intensity of light energy is measured to provide an indication of the ppm concentration.

Features and benefits:

  • Ultrasonic disc generates a continuous cleaning action within the sample cell to reduce maintenance frequency
  • Compensation for temperature and lamp deterioration minimizes re-calibration requirements
  • Long life lamp
  • Desiccant chamber keeps electronics dry in humid conditions
  • Continuous display updates every one second
  • No consumables or chemical used
  • Sample flow returns to the process
  • Sample cell can be exchanged with prepared samples for easy testing and calibration
  • Light scatter technology responds to petroleum, synthetic and vegetable oils
  • Continuous on-line monitoring without chemicals or lag time
  • Internal ultrasonic pad helps keep the flow-through sample cell clean to reduce contamination error
  • No tools necessary for routine maintenance

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.
