Reliable sensor for harsh environments

April 2017 Sensors & Transducers

Michell Instruments has on offer the new HygroSmart HS3 sensor with I2C communications protocol/slave device (BUS output), that supports a maximum speed of 100 kHz. Each slave on the I2C bus holds an individual 7-bit device address. The address byte is then followed by the op-code and eventually the payload.

Designed to withstand the kind of harsh and demanding conditions found in industrial processes, the HygroSmart HS3 sensor has a polymer tile to give long-term reliable measurements, unlike many disposable probes that have a short life within harsh conditions before needing to be replaced. In addition, it has an accuracy of 0.8% RH, making it among the most accurate and reliable RH sensors 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 life-time cost of ownership when compared to the disposable sensors.

Also available is the HygroSmart HS3 probe that consists of a solid, corrosion-resistant probe body with an interchangeable sensor. The probe offers voltage outputs of 0-1, 0-2,5, 0-5, 0-10 V and digital output signal Modbus RTU over RS-485 2-wire. 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 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.

With the HS3, users can now simply plug in a pre-programmed sensor and easily and seamlessly test wiring and alarm points. It is also possible to use the HS3 probe’s features for an OEM HS3 sensor as a diagnostic tool during testing and commissioning. As well as its ability to withstand harsh process conditions, the HygroSmart HS3 probe also gives control to the user, as it is 100% configurable. This gives users the ability to alter their RH and temperature measurements to keep in step with changes or developments in the process, with no extra cost.
