The input and output connections to the internal terminal blocks is via fitted cable glands. The internal card assembly is formed from discreet components mounted on a resin-bonded glass fibre laminate with tinned copper printed circuit conductors and gold plated edge contacts. The card has miniature multi-turn potentiometers for the setting of gain and zero. The unit provides a sinusoidal output at 3KHz for excitation of the transducer, amplification, phase sensitive demodulation, a low pass active filter to give a DC voltage output signal and has, in addition, a current output stage. | | | | | | CD • ■ CD CO | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
