    universal analog input signal conditioner

    opfest_1709811

      I'm looking for a universal analog signal conditioner to combine all my  sensor needs in one unit controlled by our CPU.

         

      have anything to recommend?......

         

      inputs for: TC(all types), RTD(4 wire 10,100 & 1000 Ohm), Thermistor(1 & 10K), S-G(120-5k Ohm), pH & ORP(10>15 input impedance), %RH,(capacitance), etc.

         

      I/O: I2C/SPI,

         

      power:2.7- 5.5Vdc

         

      we can linearize, X-Y, Polynomials, math. functions, zero, span tare etc in our PIC18F87 and selection of function desired(TC/RTD?S-G etc.)

         

      if needed we can put a FET op amp for High impedance ckts

         

      thanks
