3-pin pressure sensor - Sensors - Arduino Forum

Hi guys, I have some problems dealing with a pressure sensor. It's a 3-pin sensor (+ / - / signal), which get's 5V input and delivers a signal up to 4.5V. I attached the datasheet of the sensor and my wiring. I am not sure which of the sensor pins has which function, but I tried all combinations and in close all cases I got a 5V output even the sensor is just laying around and should give something around 0,5V. Only with one combination I received a signal of around 2,5V which is also to high.
