Overview of the 501 Viscometer Sensor

Quick 501 Sensor HighlightIt's no secret to anyone familiar with Cambridge Viscosity that we're proud of our sensor technology. We talk a lot about our oscillating piston technology, which is based on an electromagnetic concept, where two coils move the piston back and forth magnetically at a constant force. (You can see the video showing how it works here.) The patented concept makes for a highly stable, low maintenance viscometer that maintains calibration and needs minimal service. It literally has only one moving part, and no wear points. The most convenient part is that our sensors are self-cleaning. 

For this week's blog, we wanted to highlight our 501 sensor. The 501 is tiny—it fits in the palm of your hand and accommodates a small 1/2" NPT threaded fitting. It's commonly used in compressors, where there is very little room, but other applications include used oil analysis, on-engine, and hydraulic fluid—anywhere space is limited. 

It can handle pressures up to 2500 psi and temperatures up to 190° C. A built-in temperature detector (RTD) senses the actual temperature in the sampling chamber, while a constant in and out motion keeps samples fresh, mechanically scrubs the sampling area, and provides excellent viscosity tracking.

With a viscosity range of 0.5 to 500 centipoise (cP) and accuracy of ± 1.0%, the 501 sensor is powerful and versatile. All wetted parts are 316L stainless steel for enhanced corrosion resistance.

Recommended fluid flow over the sensor is up to 30 cm/sec.
