CXTLA02 SOLID STATE, LOW RANGE, ANALOG SERIES Small, Low-Cost, Rugged Vibration Resistant O 20 Range, 100 mV/ Output Fully Conditioned Analog Outputs Applications Scissor Lifts CXTLA02 Static Platforms The CXTLA dual-axis analog tilt Unlike other micro-machined devices, Alignment Systems sensor offers high-resolution, the CXTLA Series maintains its accuracy, and fast response in an Laser Leveling accuracy and stability over inexpensive, easy-to-use package. The temperature: < 2 of arc over the CXTLA series design centers on a highly range 0 to 70 C. The output can be stable silicon micro-machined user corrected for temperature with capacitive inclination sensor element. the -T option, yielding accuracy to The CXTLA series is fully signal within 0.5 over the angular range. conditioned with high level analog output(s), and optional analog A typical configuration using CX- temperature signal. TLA sensors is shown below. Each module is factory calibrated, tested Micro-machined devices, perfected in and includes a calibration sheet. The automotive safety applications, offer module can be securely attached several distinct advantages over fluid, using screws or adhesive. The CXTLA electrolytic, and pendulum-based is available in a standard nylon or sensors. Like other solid-state devices, high temperature aluminum pack- they are more reliable than their me- chanical counterparts. In a package smaller than many pendulum or fluid sensing elements, completely inte- grated electronics eliminate the need for external components.
