The DT2040: 20/40 Channel Vibrating Wire/Thermistor Data Logger is a low cost, battery powered data logger, designed for reliable, unattended monitoring of up to 40 sensors which may be any mix of vibrating wire sensors and thermistors, typically 20 vibrating wire sensors with their associated thermistors and/or thermistor strings.

The DT2040 connects to all vibrating wire sensors including piezometers, crack meters, and strain gauges; however, it will not connect to vibrating wire sensors with auto resonant circuitry. Surge protection is available on each channel with ground lug on exterior of enclosure (ground rod required).

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 kilometers without loss.

Data logger setup and data collection is done using a laptop. RST’s DT Logger Host Software is also included.

The DT2040 can also be equipped with an optional radio antenna (see photo) to incorporate it into an RSTAR, RSTAR Affinity, or DT LINK wireless system (see separate brochures for further details).
