Many of SensComp’s customers have questions on the best ways to mount or enclose SensComp’s 600 Series and Piezoelectric Sensors.
As a Leading Manufacturer of Ultrasonic Sensors, SensComp has Capabilities for a Wide Range of Solutions
Let’s start with SensComp’s 600 Series, Mini, and Smart Sensors. You can mount these sensors to a simple thin plate of any rigid material, such as steel, fiber board, aluminum, etc. Using a 1.5” hole saw, drill the hole in the material and remove all burrs. The sensor diameter at its widest is 1.520”, so the hole diameter will have to be increased by about 0.010”, for a final diameter 1.530”. You can use a file or deburring tool to open up the hole. It is important that the sensor moves freely in the hole. Any pressure applied to the sensor may distort the gold foil and affect performance. A quick way to determine if there is any binding on the sensor is to turn the plate over and the sensor should fall out. It is then time to fasten the sensor to the plate.
You can use a variety of adhesives, but clear silicon and 2-part epoxy work the best. It is not necessary to put the adhesive around the entire diameter of the sensor. 3-4 dabs equally spaced around the diameter is usually sufficient to hold the sensor firmly in place. Be careful not to get the adhesives on any other part of the sensor. SensComp also offers an enclosure for these sensors. Click here for more information. Any enclosure used for electrostatic sensors must have a vent hole of 1/8” diameter or larger to perform properly. Therefore, any application that requires a totally sealed enclosure is not possible.
SensComp’s piezoelectric sensors can also be mounted on plates and in enclosures. Follow the same procedure for mounting electrostatic sensors. Again, you want to be sure the sensor is freely mounted in the hole of the material, as not to effect the performance of the sensor. Use silicon or 2-part epoxy to secure the sensor in the mounting hole. Piezoelectric sensors can be used in enclosures that have no venting requirement. You can use IP65 and IP66 rated enclosures.
