We had an enquiry from a customer building a weighing station for a packing line, using a load cell that needed a panel meter to read out the weight and drive a fill-control relay. The ADtek CS2-SG is built for exactly this – load cell and strain gauge signals, with field calibration so it can be tuned to the actual mechanical setup rather than just a factory-generic scale.
This looks simple, but load cell signals are rated in mV/V (millivolts per volt of excitation), and the meter has to be set to the right sensitivity range for your sensor: 0~1.0/2.0/3.33/4.0 mV/V on the low range, or 0~10.0/20.0/40.0 mV/V on the high range. The CS2-SG also supplies its own excitation voltage to the load cell (DC5V or DC10V, 40mA), so you don’t need a separate excitation supply.
In actual application, the CS2-SG calibrates digitally from the front key – you can do a field calibration directly with your actual load cell or strain gauge input (high and low points) to match your mechanical structure, without disturbing the factory accuracy and linearity calibration underneath. It gives 16-bit A/D resolution, accuracy of ≤0.04% of full scale, a 15 cycles/second sampling rate (or 60 cycles/second in high-speed mode with 0~6000 scaling), and response time of 100ms or better under standard settings. It comes with 4 relays (Hi/Lo/Hi Hold/Lo Hold/Go, with delay and hysteresis, or as remote control), 3 external control inputs (including Tare), and analogue output or RS-485 Modbus RTU as options. Useful for weight/force testing, leak testing by tare and relay function, or fill control on packing and filling machines. CE and RoHS compliant.
From our experience, before we quote this, we would normally check your load cell’s rated output (mV/V) and excitation requirement, whether you need high-speed sampling, how many relays and what functions, and whether you need the analogue or RS-485 option. Hope this helps.
