The CXTLA series design centers on a highly stable silicon micro-machined capacitive inclination sensor element. The CXTLA series is fully signal conditioned with high level analog output(s), and optional analog temperature signal. Micro-machined devices, perfected in automotive safety applications, offer several distinct advantages over fluid, electrolytic, and pendulum-based sensors. Like other solid-state devices, they are more reliable than their mechanical counterparts. In a package smaller than many pendulum or fluid sensing elements, completely integrated electronics eliminate the need for external components. Unlike other micro-machined devices, the CXTLA Series maintains its accuracy and stability over temperature: < 2 of arc over the range 0 to 70 C. The output can be user corrected for temperature with the -T option, yielding accuracy to within 0.5 over the angular range. A typical configuration using CXTLA sensors is shown below. Each module is factory calibrated, tested and includes a calibration sheet. The module can be securely attached using screws or adhesive. The CXTLA is available in a standard nylon or high temperature aluminum package.

The response of the tilt sensor depends on the magnitude of gravity parallel to the sensor element. The output of the tilt sensor will be an offset voltage plus the voltage response proportional to the amount of gravity measured by the sensor. Using the CXTLA Sensor The voltage response of the CXTLA is proportional to the tilt angle. Accurately measuring tilt angle involves solving the equation shown at Figure 1. To solve this equation the Zero Angle Voltage and Sensitivity must be determined prior to use. Crossbow provides this information on a calibration sheet with its CXTLA products.
