... that this sensor is very imprecise?
Also, the recommended drive circuit might probably work on the living room desk but hardly in a rough industrial environment. Connecting the sensor cable directly to the inverting input of an operational amplifier without any filtering can result in wild oscillations and instability. Why not making the sensor resistance part of a CMOS555 RC-oscillator and measuring the resulting frequency or period by the help of a 8051? Kai |
