Data Acquisition Systems

Kingmach data acquisition systems are built to sit between field sensors and the engineer's dashboard, and that position shapes everything about the design. The front end supports multiple excitation and readout methods: vibrating wire, 4-20 mA loop, half-bridge and full-bridge strain, thermistor, and linear potentiometer. This means one logger can handle a mixed array of piezometers, joint meters, and temperature sensors without separate signal conditioners. Channel count is configurable, typically starting from 8 and scaling up to 64 or more with expansion modules. For a medium-scale slope stability project, that might translate to one main unit plus two satellite nodes connected over RS-485. Sampling intervals can be set independently per channel group; a rainfall gauge might log every minute while a thermistor chain records every hour. Data is stored locally in non-volatile memory and pushed to a remote server via 4G, Ethernet, or radio. The protocol stack is standard Modbus TCP/RTU, so integration with SCADA or third-party data management platforms usually takes a few hours rather than days. Power consumption is designed around solar-battery field operation, with deep sleep modes that keep a 30W panel sufficient for all but the most channel-dense setups. Enclosures are IP65 as a baseline, with optional IP67 for temporary works in wet conditions. Because no two sites are identical, we handle custom wiring looms and terminal assignments at the factory. Configuration is done through a desktop utility that scans the bus, identifies connected modules, and lets the operator assign sensor types and calibration factors without writing scripts. The same utility generates a channel map importable into popular analysis software. Calibration data and timestamped readings are stored in clear-text formats, so you are never locked into proprietary viewers. Globally, we deliver through regional distributors who keep spare parts and provide on-site start-up assistance. The system components carry a two-year warranty, and technical support is available by email and phone with engineer-level contacts rather than call center staff. For organizations managing multiple instrumented sites, we offer a centralized data viewing portal that can be branded with the client's logo and user roles. In short, the DAQ line aims to remove the usual friction points: closed protocols, rigid channel assignments, and power budgets that don't align with remote site realities.
