RST Instruments offers many solutions for reading, displaying, and logging data from its instruments. In situations where automatic transmission of data to a central terminal is either undesirable or impossible, RST’s readout units allow you to collect data, view it on site, and later export that data to a host computer in a variety of formats.
The time you spend taking readings in the field is valuable, which is why all of RST’s readout units are made to store data from over 250 distinct instrument locations per route and have electronic download times of 15 seconds or less, allowing you to get the information you need quickly and spend less time on back-and-forth trips.
Four readout units are available to suit the kinds of sensors you need to collect data from. All come in sealed weatherproof cases so that you won’t have to worry about damaging your tools while you’re in the field. The VW2106 vibrating-wire readout reads, displays, and logs data from both vibrating wire sensors and thermistors; the QB120 resistance strain gauge readout interfaces with 1/4 bridge strain gauges and TENSMEG tension-measuring gauges; and the SG350 bridge transducer readout, bridge transducers—all three of which run on field-replaceable AA batteries. The C109 pneumatic readout reads, displays, and logs data from all pneumatic transducers, including piezometers and total earth pressure cells, and is powered by a long-life lithium battery.
RST also produces terminal stations that can be installed on site to manually read vibrating-wire sensors and their thermistors. Each station can connect to either 12 or 24 sensors, depending on the model. And all terminal station models are NEMA 4X and meet IP65 criteria for demanding conditions.
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!
