The box-type tilt meter consists of a uniaxial MEMS sensor mounted inside a compact, weatherproof enclosure. These tiltmeters are suitable for monitoring small changes in inclination and vertical rotation of structures. The tiltmeters provide a relatively low-cost system that offers excellent resolution and long term stability.
The box-type tilt meters come in two variants:
The tiltmeter can be monitored with any suitable portable readout unit or connected to a data acquisition system using Busmux or multiplexer. The Model EAN-91M tilt meter output is 4 V nominal at ± 15°. This output can be transmitted over long distances without any signal degradation.
Model EAN-93M box type digital tilt meter consists of a uniaxial MEMS sensor mounted inside a compact, weatherproof enclosure. These tiltmeters are suitable for monitoring small changes in inclination and vertical rotation of structures. The tiltmeter data can be logged and transferred through our model ESDL-30 compact wireless data logger.
The box-type tiltmeters are fixed onto a vertical or horizontal surface either directly using 4 mounting screws or fasteners or using a mounting kit that allows more flexibility in mounting the tiltmeter. The movement of the structure causes a change in the tilt of the tiltmeter, which results in a change in the output of the sensor. Measurement can be made on horizontal or vertical surfaces. Subsequent sets of readings show how the structure is behaving and will indicate permanent deformation as time progresses.
