The SA40011- Dual Axis Signal Conditioning Module is a bipolar DC input/output operated device, specifically designed to interface directly with the entire line of SP5000 Series Dual Axis Tilt Sensors. This PC board mountable module internally converts the DC input voltage into an AC excitation voltage for the sensor, and demodulates the sensor output into a smooth amplified DC output voltage. Incorporating a proprietary signal processing algorithm, and an external temperature compensation sensor (optional), normal measurement errors are severely reduced. The SA40011 also features overload protection, and is 100% reliability tested to provide the highest quality available.

   Temperature Compensation
      - Temperature compensation of the assembly (module and sensor) can be accomplished using an external silicon temperature sensor (KTY81-120) and resistor (47k ohm typical). With this configuration, it is possible to reduce the scale temperature coefficient error from a 0.3%/CO (nominal), to 0.03%/CO (nominal). Please see wiring diagram for connection points.
