altTURCK (Minneapolis, MN) offers a single-axis inclinometer sensor for detecting angular tilt with an adjustable measuring range of 360 degrees. The sensor measures angular tilt in reference to gravity. It uses a MEMS device that incorporates a microelectromechanical capacitive element into the sensor. The device consists of two parallel plate electrodes, one stationary and one attached to a spring-mass system. As the inclinometer tilts with the attached equipment, its acceleration produces deflection in the non-stationary electrode. The result is a measurable change in the capacitance between the two plates that is proportional to the angle of deflection. The signals produce a single analog voltage output or current output. The MEMS technology uses a microboard design. The sensor is IP68 rated and has a temperature range from -30 to 70 °C.
