WS18DS Water in Oil Sensor

The Pall WS18DS is designed to offer reliable measurement of water content in oils in demanding industrial applications. In addition to being able to measure both relative humidity and temperature to highly accurate and precise levels, the WS18DS is also capable of calculating the parts per million (PPM) content of dissolved water in oil.

The Effect of Water in Oil
Water contamination in fluid can cause numerous problems such as additive depletion, oil oxidation, corrosion, reduction of dielectric strength. These costly problems can be averted with continuous monitoring of oil water content so that timely action can be implemented.

Hydraulic, lubrication and insulating fluids, and diesel fuels should be operated without the presence of free water and with dissolved water levels at 50% saturation or considerably of insulating oils.

Measures the dissolved water content in oil and displays this measurement in either % saturation or PPM.
1. 3.5" TFT Colour Display
  • Instrument data can be viewed from the 3.5” colour display and can also be downloaded to external computer for more in-depth data analysis.
2. Enclosure
  • Electronics protected against mechanical damage
  • Mounting accessible with closed cover
  • IP65 / NEMA4 rated
3. Outputs
  • 2 analogue outputs current / voltage
  • Modbus RTU
  • Configurable via display or software
  • 2 switch outputs (optional)
4. USB interface
  • Simple connection to external computer through micro-USB
5. Probe
  • Suitable for temperatures up to 180 °C (356 °F)
  • Suitable for pressures up to 20 bar (290 psi)

Display

  • Shows up to 4 measurands simultaneously
  • Display alarms for customer specific limits
  • Configure and scale outputs
  • Configure Modbus settings
  • All measured and calculated values logged continuously
  • Logs up to 3 months depending on sampling rate
  • Download data via integrated USB port and Pall software
  • View all device relevant information in a matter of clicks

Modular Housing

The upper part of the transmitter that encloses the electronics can be separated from the base unit for service or adjustments. The base remains mounted and the cabling intact, even when the unit is being serviced.

A polycarbonate plate on the inside of the housing prevents damage to the electronic board during installation or service.
