The DTSAA Data Logger enables stand alone and radio-telemetry data collection of Measurand ShapeArray instruments.

ShapeArray instruments can be incorporated into a wireless, or stand alone, data collection system by using the DTSAA Data Logger. The DTSAA can read ShapeArray sensors configured in low power mode. If configured with an RSTAR radio, the data logger will transmit data to a RSTAR hub allowing automated data conversions.

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!
