Description
PCE-MWM 200 Humidity Detector / continuous Moisture Content in Oil, Diesel, fuel, sand, gravel
The humidity detector is a sensor for measuring moisture of sand consisting of a central probe surrounded by four other probes. The probes and sensor housing are made of stainless steel AISI 321. Our humidity detector is ideal for installation in tanks with liquid materials such as fuel oil, sludge from cement production, fuels (CWF). Bolt diameter - 12 mm, distance between the central and the surrounding probes - 25 mm. This large distance between the probes ensures high resistance to clogging.
The top of the sensor serves as a coupling with a female thread, which enables the mounting of the sensor on a pipe with a 33 mm diameter. The cable that connects the sensor and the electronic unit is installed in the airtight tube. Such a sensor assembly allows variations of the immersion depth into a container and humidity measurements at various levels.
Stainless steel - use and special dielectric spacers offer high corrosion resistance. Furthermore, this allows moisture measurement in pipes with temperatures up to 145 °C. On request, by using ceramic materials, measurement of temperatures up to +800 °C would also be possible. In this case, the accuracy of humidity measurement remains practically unchanged.

Please note that we will need further information to provide a final price for supply and fit. We will need to know what materials are to be measured, we will need samples of the material, and we will need a technical drawing showing where the sensor is to be installed. | |
