Fluid pressure transducer

I've a few laying around, that I have a local community use for one, but don't know how to use it. 0 to 10 bar, but the manufacturer's model number gives nothing on google. No idea if bridge of strain gauges, active vibration mode or what.

5 wires plus screen, about 40/45 Kohm mutually between 3 wires , no ohms with/between the other 2 wires and no DVM-D test forward voltage on any wire to wire connection either way round.
