The AccuStar® Electronic Clinometer is an extremely accurate angle measurement device. This compact and rugged sensor is ideal where space is critical and environmental conditions are serious design concerns. The heart of the system is a patented, capacitance-based sensor with no moving parts. When rotated about its sensitive axis, this unique sensor provides an exceedingly linear variation in capacitance, which is electronically converted into angular data. The sensor and low-power CMOS electronics are encased in a rugged plastic housing ready to install as a system component or as a stand-alone device. Total Range: ±60° Linear Range:±45° Threshold: 0.001° Linearity CE certified Just 2" in diameter Rugged plastic housing Extremely accurate Weighs only 2 oz.
