Help to identify pressure sensor

Hi,
I pulled this sensor from a tire air-compressor, which I believe measures the pressure while operating. I couldn't find any datasheet, so was wondering if you can help identifying or at least give an idea how would it operate. It would be great if I can build some circuits around it for the fun of it!
Thank youIMG_3469.JPEG

It's a 7bar (700kPa) absolute pressure sensor manufactured by SIMST in China

5v 1mA excitation, output is 100mV -30/+50mV at full scale with 0Pa offset +/-50mV, so calibration required. Open to atmosphere should give about 14mV assuming vacuum is 0mV, and unit is typical for FS range.

Datasheet (such as it is) attached. Have fun.
