load cell data acquisition

Kingmach’s load cell data acquisition modules convert analog strain gauge signals into digital engineering values using 24-bit ADCs, with per-channel sampling rates adjustable from 1 Hz to 1 kHz. Inputs accept standard mV/V outputs from load cells, pressure cells, and load pins, as well as 4-20 mA and 0-10 V signals from amplified sensors. Digital communication ports provide RS-485 (Modbus RTU) and Ethernet (Modbus TCP/IP) as standard, with optional CAN bus for vehicle or industrial applications. The front-end offers programmable gain, low-pass filtering, and bridge excitation of 5 V or 10 V, supporting full-bridge and half-bridge configurations. Power can be supplied from 12-24 VDC or a battery-backed solar setup for remote monitoring. Enclosures are rated IP65 to IP67, with surge protection on all terminals. Because Kingmach is a manufacturer of geotechnical instruments, the unit can be delivered pre-terminated for specific load cell models, with cable lengths and connector types matched to site drawings. Custom channel counts—from 2 to 32—and mixed input types per module are available. The open architecture means data can be pushed to third-party SCADA, FTP servers, or Kingmach’s own cloud platform. Technical support covers sensor wiring, network troubleshooting, and firmware updates, backed by a global distribution network.
