Model 781 is a precision, 2-channel signal conditioning unit for all electrolytic tilt sensors. It provides peak performance from your 755, 756, 84053 and 84064-02 Miniature Tilt Sensors. To build Model 781, we package an 83162 signal conditioning card in a rugged aluminum case with screw terminals on the rear panel for sensor connections, power input, and signal output. Three switches on the front panel control gain and low-pass filter settings, and power on-off.
Model 781 generates a balanced AC sensor excitation, then amplifies, rectifies and filters the sensor outputs to produce high-level DC signals proportional to the tilt angle. It also operates a LM35 temperature sensor and will drive tilt and temperature signals over 1000m cable lengths. This signal conditioner is excellent for laboratory and factory applications that require remote operation of one or two tilt sensors.
