MEMS Inclinometer Sensor Detects Angular Tilt

The company’s latest dual-axis inclinometer sensors for angular tilt detection feature compact rectangular housings and mount at ±10?, ±45?, ±60?, and ±85? angles. The components measure angular tilt in reference to gravity employing a MEMS device, which integrates a micro-electro-mechanical capacitive element into the sensor. The element uses two parallel plate electrodes: one stationary and one attached to a spring-mass system. Movement causes acceleration that produces deflection in the non-stationary electrode that results in a measurable change in the capacitance between the two plates that is proportional to the angle of deflection. These signals are conditioned to provide two analog voltage (0.1 to 4.9 Vdc) or two current outputs (4 mA to 20 mA). Additionally, the inclinometers carry an IP 67 rating and operate over a temperature range from -30?C to 70°C. TURCK INC., Plymouth, MN. (800) 544-7769.
