Operation
The WCS-300 is a capacitive proximity sensor, operates with beat frequencies with values
close to 1 MHz and despite the small power, has the ease of propagation, primarily through
metallic bodies. Installing several sensors on the same surface, interactions may occur between
them.
Besides, the WCS-300 detects materials in direct proportion to its mass, in other words, if
there is one body close to the sensor with more massive than the material to be measured or
detected, adjustment range will be considerably diminished, since the sensor is on the verge of
switching.
For these reasons, when the WCS-300 is applied to the measurement, sugarcane level
indication, feed systems such as Chute-Donnelly or metallic silos, is necessary to build a non-
metallic material area with low-mass to install it.
Do not place the capacitive sensor directly in contact with the part to be measured. Its
sensitivity is, in most cases, sufficient to "through" acrylic (or other non-metallic material) and
detects the product. This facilitates maintenance and preventing wear of the sensing surface.
