The EAN-70M (MTI.EWS.ER.M-EAN-70M) portable tilt meter incorporates a sensor based on precision MEMS accelerometer technology. It is housed in a rugged frame with machined surfaces that facilitate accurate positioning on the tilt plate. This portable tilt meter is suitable for monitoring change in the inclination of a structure. It has excellent temperature stability. The tiltmeter system includes tilt plates, a portable tilt meter, and a readout unit. Die-cast aluminum tilt plates, available from Sensor are dimensionally stable and weather resistant. Tilt plates are mounted on the structure at specified locations. Tilt readings can be obtained quickly and easily by a single operator.
