RST Portable Tiltmeter
The RST Portable MEMS Tiltmeter utilizes a MEMS tiltmeter to measure tilt in either one or two axial planes perpendicular to the surface of the base plate. The output is a digital output and is directly proportional to the sine of the angle of tilt. In the horizontal position, the DC output is zero. Portable MEMS Tiltmeters require placing the tiltmeter in a reproducible position on a reference plate attached to the surface being monitored. It is designed for applications where a large number of measuring points are to be observed.
RST In-place Tiltmeter
RST’s Tiltmeters measure tilt in two axial planes with a perpendicular gravity vector. The tiltmeter is intended to be permanently installed to provide long-term observation with maximum resolution and sensitivity and conveniently accommodates manual monitoring or remote data acquisition.
RST Tilt Beam
MEMS Tilt Beams measure differential movements in structures and consist of a MEMS sensor mounted on a rigid, fibreglass beam. The beam is mounted on anchor bolts set into the structure. They can be installed on any structure by joining together lengths of beams and are extremely accurate in generating movement profiles over long distances. Readings are taken with a manual readout by connecting at the end of the single cable linking all the bussed beams, or with a data logger at a remote monitoring station. Site-specific, near-real-time monitoring software is available.
RST Uniaxial/Biaxial Digital Tilt Loggers
RST’s family of Digital Tilt Loggers are low-cost, battery-powered data loggers and tilt meters in a single, compact unit. They measure tilt in either one (uniaxial) or two (biaxial) perpendicular axes in the plane of the base and are intended to be permanently installed to provide long-term observation with maximum resolution and sensitivity.
The DTL201B (uniaxial) and DTL202B (biaxial) Digital Tilt Loggers are designed for either manual monitoring or remote data acquisition. The optional radio antenna allows them to be incorporated into an RSTAR Array Radio System for automated, remote data acquisition. The optional radio antenna can also be used for enabling the DTL201B and DTL202B for RST’s DT LINK which allows wireless collection of data logger data in hard-to-access areas.
RST’s Digital Tilt Loggers consist of one or two MEMS tilt sensors, a battery supply, non-volatile memory, a USB cable and Windows® host software. The electronics are housed in a NEMA 4X (IP-65) enclosure for environmental protection and are typically bolted to the structure via a mounting plate or bracket.
