Now I have one from ebay but seems doesn't work?
I try connect on pin 1 +IN 5V, pin 3 and 4 -IN zero(GND) and try measure mV on pin 2(+OUT) and 5(-OUT) but there is only half voltage (+-half) without any changes by change pressure. And what is very interesting - on output +OUT is minus and on output -OUT is plus .....strange
Something wrong with my circuit or this sensor is bad?
