Overview

The DT2055B: 5/10 Channel Vibrating Wire/Thermistor Data Logger is a low cost, battery powered data logger, designed for reliable, unattended monitoring of up to 10 sensors which may be any mix of vibrating wire sensors and thermistors, typically 5 vibrating wire sensors with their associated thermistors.

The DT2055B connects to all vibrating wire sensors including piezometers, crack meters, and strain gauges; however, the DT2055B Ten Channel Data Logger will not connect to vibrating wire sensors with auto resonant circuitry.

Vibrating wire sensors have unique advantages in geotechnical applications, as the frequency output of the gauge is immune to external electrical noise, able to tolerate wet wiring without signal degradation, and able to transmit the signal up to 1.6  kilometres without loss.

Data logger setup and data collection is done using an Android-enabled handheld device or a laptop. DT Logger Host Software is also included. A single gland option (DT2055B-T) is also available for Multi-Point Vibrating Wire Piezometer Strings or Thermistor Strings.

The DT2055B can also be upgraded with an optional radio kit and antenna to incorporate it into an RSTAR or DT LINK wireless system. The DT2055B can also be added to an RSTAR Affinity radio network to complete backwards compatibility requirements.

Product Features
