The box type tilt meters consist of uniaxial MEMS sensor mounted inside a compact, weatherproof enclosure. These tilt meters are suitable for monitoring small changes in inclination and vertical rotation of structures. The tilt meters provide a relatively low cost system which offers excellent resolution and long term stability. The box type tilt meters come in two variants:
The box type tilt meters are fixed on to 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 tilt meter. Movement of the structure causes change in tilt of the tilt meter, which results in change in output of the sensor. Measurement can be made on horizontal or vertical surfaces. Subsequent sets of readings, shows how the structure is behaving and will give an indication of permanent deformation as time progresses.
Model EAN-91M tilt meter can be monitored with any suitable portable readout unit or connected to a data acquisition system using Busmux or multiplexer. Model EAN-93M tiltmeter data can be logged and transferred through our model ESDL-30 compact wireless datalogger.
