Configurable, Low Differential Pressure Transducer System Monitors Auto Cabin Pressure

Northridge, CA –Validyne Engineering introduces the World’s first Automotive (Transportation) Dynamic Cabin Pressure Checker. VPAS, Vehicle Pressure Acquisition System, is used to detect rapid pressure changes due to: Sun roof opening, side or rear window openings, windshield leak detection, and HVAC testing and verification.

According to Richard Ganz, Validyne's Director of Business Development "A new wave of automation has recently been ushered into the Auto Industry: from self-parking to self driving systems such as the Tesla Model S and the Mercedes F 015. Validyne is committed to support the sensors and related systems that support a safe and comfortable driving experience."

A World Leader in Variable Reluctance Technology (VRT) since 1968, Validyne has a rich history of providing standard and custom solutions to the Auto industry. In the Mid 90's, Validyne designed to General Motors (GMC) specifications, a Vehicle Standard Thermal Instrument. Commercially available and in use today as VDAS, it is an in-vehicle data acquisition system (DAQ).

Hyundai Motor Company (HMC) has announced its desire to move forward and procure a VPAS production system for use as a standard efficiency test and check across all Hyundai and Kia vehicles.

A portable, vehicle-powered VPAS is designed to measure, record and display sensor readings from 1 to 16 channels. The VPAS software is integrated for PC or iPad and is used to measure vehicle cabin pressures under various conditions. A unique reference to atmosphere can be enabled at any time.

The VPAS system is comprised of a Validyne USB2250 sensor interface with on-board signal conditioning for VRT or any other manufacturer’s pressure sensor. Validyne model DP103 pressure sensors – included on VPAS – can measure full scale ranges as low as +/-0.10 In H2O and up to +/-55 In H2O.

Pressure readings are available for continuous display and graphing on a laptop PC or iPad via USB interface integral to the VPAS. The transducer readings are calibrated for In H2O and the data is recorded to a .csv file and displayed graphically in real time.
