Presentation

The Model 781 is a high-precision signal conditioning module for bi-axial miniature inclination sensors. It drives 2 axes (X, Y) and an LM35 temperature sensor. The output is a DC voltage of ± 8 VDC (Differential ± 16 VDC) and is linear with inclination. Analog filter gain and time constant are adjustable via front-panel switches. Analog output signal range is 1000m. The distance between the sensor and the electronics must not exceed 100m.
