remote data loggers

Kingmach remote data loggers are built around modular input channels to accommodate different sensor types. Typical configurations support 4–16 analog or digital inputs, with expandable options for larger arrays. The input modules are field-swappable, so a unit configured for vibrating wire sensors can be reconfigured for 4–20 mA transmitters or SDI-12 devices without replacing the entire logger. Sampling intervals are programmable from 1 second to 24 hours, and data storage uses non-volatile memory with capacities ranging from 8 MB to 32 MB—enough for months of unattended recording. Communication-wise, the standard model ships with a 4G LTE modem and an integrated antenna, but RS-232/RS-485 ports are also present for local data download or connection to radio modems. Power comes from an internal rechargeable battery backed by a solar panel input, with operating temperature ranges typically between -20°C and 60°C. Enclosures meet IP66 standards, so they survive heavy rain and dust. We see a common pain point is logging data from mixed sensor types in the same location. The firmware allows you to mix excitation voltages and signal conditioning per channel, so a single logger can handle both a thermistor and a load cell without external adapters. For users who need to push data into custom SCADA systems, the logger supports Modbus TCP/RTU, FTP upload, and MQTT for cloud platforms. We often work with engineering firms to pre-configure units before shipping, cutting setup time on site. While these loggers are designed for geotechnical applications, they’ve also been used in environmental monitoring and structural health, where the same sensor compatibility and remote access add value.
