Data Loggers
Battery-powered wireless loggers that read vibrating wire and digital sensors on site and send the data by long-range radio.
DP-LG3-VW8DP-LG2-SDigital Logger
Overview
The DP-LG3-VW8 Vibrating Wire Data Logger 8 Channel reads up to eight vibrating wire gauges with thermistors, or multi-gauge load cells. The DP-LG2-S Data Logger RS 485 Serial reads a string of addressable digital sensors such as the DP6x16K1 Tilt Meter and DP-89K Inclinometer. The Digital Logger reads Modbus RTU and other digital instruments, including in-place inclinometers and shape arrays.
Loggers store readings if the radio link is lost and send them when it returns. They run on internal batteries, with external or solar power for larger strings.
