In-Place Tilt Meter


In-Place Tilt Meters measure tilt in either one or two axial planes perpendicular to the surface of the base plate. Central to the tilt meter is a MEMS (Micro-Electro-Mechanical System) sensor that provides proven installation longevity and reliability. The unit is intended to be permanently installed to provide long-term observation with maximum resolution and sensitivity, and is conveniently designed for manual monitoring or remote data acquisition.

In-Place Tilt Meter systems consist of a tiltmeter mounting plate (horizontal or vertical), electrical cable, and a data logger or readout. The tiltmeter may either be uniaxial or biaxial and can be supplied with a digital (RS-485), analogue voltage, or 4-20 mA output. The electronics are housed in a NEMA 4X (IP-65) enclosure for environmental protection, which is typically bolted or bonded to the structure under monitoring.
