Overview

RST’s family of Digital Tilt Loggers are low cost, battery powered data loggers and tilt meter 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 consists of one or two MEMS tilt sensors, a battery supply, non-volatile memory, USB cable and Windows® host software. The electronics are housed in a NEMA 4X (IP-65) enclosure for environmental protection, and is typically bolted to the structure via mounting plate or bracket.

Speak with an Expert

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
