- A sensing probe immersed in the fluid to directly monitor dissolved water content and temperature
- Water content expressed as % saturation or PPM and temperature in ®C or ®F
- High temperature sensing
- Simple to operate
- Robust modular housing and sensing probe designs
- Available with or without display
- Included PC configuration software with RS232 communication cable
- Two relay outputs standard (except if RS485 output is ordered)
- Optional RS485 output (not available with relay outputs)
- Two freely scaleable and selectable analogue outputs, 4-20 mA, 0-5 V or 0-10 V (factory default setting is 4-20 mA)
- Simple and flexible installation
The Pall WS08 Series water sensor provides precise and reliable measurement of dissolved water content in industrial process fluids. It is ideal for in-line monitoring of moisture in hydraulic, lubrication and insulation oils, contributing to the predictive maintenance of plant and machinery.
Specifically designed for harsh industrial environments the WS08 Water Sensor features a modular housing concept and simple on-site
adjustment.
