SPL 571 OILSENSE™

The SPL 571 OILSENSE™ is used extensively for compressor, used oil analysis, on-engine and hydraulic fluid applications. It is ideal for installations where form factor and small sample volume are important.

Our viscosity management technology is based on a simple and reliable electromagnetic concept. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston’s two-way travel time to measure absolute viscosity.

A built-in temperature detector (RTD) senses the actual temperature in the sampling chamber. Constant in and out motion keeps samples fresh, mechanically scrubs the sampling area and provides excellent viscosity tracking.

The SPL571 OILSENSE installs neatly into a 1/2” block fitting or tee. Measurements can be made in any of 6 different 20:1 viscosity ranges between 0.5 and 500 centipoise (cP). Recommended fluid flow over the sensor is up to 1.0 ft/sec.

Key Features:

  • Easily installed and serviced
  • Internal platinum temperature probe  
  • Simple to clean
  • No seals
  • Proven technology
  • Mates to 13/16-20 UNEF threaded opening
  • Correlates with ASTM D445.
