 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.
*NOTE: ALL ATEX SENSORS ARE SPL ONLY (L = hard wired, C = connector).
