Humidity probe for tough processes

September 2016 Sensors & Transducers

Michell Instruments has introduced its new HygroSmart HS3 probe, designed to withstand the kind of harsh and demanding conditions found in industrial processes. Unlike many ‘disposable’ probes that have a short life under harsh conditions before needing to be replaced, the HygroSmart HS3 sensor has a polymer tile to give long-term reliable measurements. In addition, it also has an accuracy of 0,8% RH, making it among the most accurate and reliable RH probes on the market, as well as allowing for longer recalibration periods.

This not only gives peace of mind to process operators, but also provides a low cost of ownership when compared to disposable probes. The HygroSmart HS3 consists of a solid, corrosion-resistant probe body with an interchangeable sensor. When recalibration is due, the old HygroSmart HS3 sensor is simply exchanged for a new, freshly calibrated one. This simple procedure takes only a few seconds to carry out with the probe itself remaining installed. Replacing just the sensor, rather than the whole probe, is not only quick and simple, it also saves users money over the lifetime of the probe.

In most industrial applications, RH probes have to withstand vibration, exposure to water, occasional heavy shocks and high levels of electrical interference. The HygroSmart HS3 body is designed to cope with all these environmental factors. As well as the solid body, the probe also has a 10 bar pressure rating, rfi/emc electrical noise approvals and IP67 ingress protection rating.

The probe is 100% configurable, which gives users the ability to alter their RH and temperature measurements to match changes or developments in their process, with no extra cost.
