Reliable Pressure Compensation Combined with Component Protection against Liquids, Dirt and Other Unwanted Agents

Schreiner ProTech’s Mini PCS Ensures Maximum Measuring Accuracy of First Sensor’s Air Conditioning Control Units

In addition to effective pressure compensation, the mini PCS from Schreiner ProTech delivers reliable protection against intrusion of liquids and dirt for the air conditioning control unit from First Sensor. Mini PCSs are dispensed via the Slimline Label Feeder from pb tec solutions.

The mini pressure compensation seal (PCS) from Schreiner ProTech was selected by First Sensor, a global leader in sensor technology, as the closure solution for the housings of its air conditioning control units. The small, self-adhesive membrane combines effective equalization of pressure differences inside the housing with reliable interior protection against liquids, dirt and other harmful agents. By combining these functional features, the mini PCS assures the accuracy of sensors used for measuring volumetric flow rates.

In air conditioning control units, even the lowest flow rates must be measured with precise accuracy – an exacting process utilizing sensitive flow sensors. To ensure best-possible results, these meters must be kept dry, and protected against intrusion from dirt and other particles. At the same time, pressure compensation must be guaranteed because both tiny dirt particles and trapped air can detune sensors, significantly diminishing their reliability.

The mini PCS developed by Schreiner ProTech as a housing closure is a small, self-adhesive membrane with a diameter of only 3 millimeters. It consists of a precision die-cut, self-adhesive ring and fitted membrane disk. This design ensures effective pressure compensation combined with reliable component housing sealing for defense against water, oils and fuels. As a result, the sensor is effectively protected and delivers exact meter readings.

For First Sensor’s assumbly line, Schreiner ProTech also found a solution for fast and easy processing of the mini PCS’s: The tiny membranes are automatically applied during the SMD assembly process using a Slimline Label Feeder from pb tec solutions. Production and deliveries of air conditioning control units using the integrated mini PCSs started September 2017.
