A global manufacturer of heavy plant machinery required an extremely robust oil level sensor to measure the level of lubricant in the gearbox of underground mining plant equipment.
One of the key customer requirements was the need for a sensor which could simultaneously report the oil temperature. The device needed to be ATEX certified in order to suit the dusty and explosive environments it was to be deployed.
The solution was based around the proven technology and robustness of Gill's standard oil level sensors. However, the sensor had to be re-engineered to integrate with the mating interface, made Intrinsically Safe (IS), and incorporate the PT thermistor into the sensor probe to provide the oil temperature measurement.
Additionally, new electronics hardware and software were developed in-house to accommodate the temperature measurement inputs and to provide a 4-20mA output.
The Gill Instruments WindObserver Intrinsically Safe ultrasonic anemometer is certified by the International Electrotechnical Commission (IEC) for use in explosive atmospheres (Ex). Find out more at gillinstruments.com
