APS 02/03 - 05/01
Air pressure sensors, 2.0 /3.0 bar absolute
The APS xx series devices are high-accuracy and reliability analogue absolute pressure sensors.
Each pressure sensor exploits the piezo-resistive properties of silicon devices. The sensing element is a Wheatstone bridge located on a mechanically shaped silicon chip. A thick film hybrid circuit for signal amplifying is included in the same package. The same circuitry provides thermal compensation and noise reduction.
These active devices are housed in hermetically sealed plastic protective casings.

Connector Pin Out
Important wiring note:
The connections A,B & C are identified as 1,2 & 3 on many commercially available minitimer connectors and may also be numerically reversed.
Looking towards the sensor so that the nipple is facing you, and the single mounting hole is at the top, the connector has 2 locating 'blocks' at the top,
(one at each end of the connector) and a single one in the middle at the bottom. Pin A (or 1) is on the Left, Pin B (2) in the centre, and Pin C (3) on the right.
