Reliable Pressure Compensation Combined with Component Protection against External Influences
Schreiner ProTech’s Mini PCS Ensures Maximum Measuring Accuracy of First Sensor’s Air Conditioning Control Units
In air conditioning control units, even the lowest flow rates have to be measured with high accuracy, for which sensitive flow sensors are used. To ensure that they deliver impeccable results, these meters must be protected against the intrusion of dirt particles. At the same time, pressure compensation must be guaranteed because both tiny dirt particles and trapped air can detune the sensor.
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 a precisely fitting membrane disk. This design ensures effective pressure compensation combined with reliable sealing of the hole in the component housing against water, oils and fuels. As a result, the sensor is effectively protected and delivers exact meter readings. For fast and easy processing of the mini PCSs in First Sensor’s operation, Schreiner ProTech found a solution as well: The tiny membranes are automatically applied during the SMD assembly process using a Slimline Label Feeder from pb tec solutions.Serial production and deliveries of the air conditioning control units using the integrated mini PCSs started in September 2017.
