We had an enquiry from a customer who needed position feedback on a valve actuator – the actuator had a built-in potentiometer for position, but no display to show where the valve was actually sitting. The ADtek CS2-PM reads that 3-wire potentiometer signal directly and shows it as a position indicator.
This looks simple, but potentiometer position feedback comes in different resistance ranges depending on the actuator or sensor, and the CS2-PM has to be matched to it: 0~50Ω/2.0KΩ on the low range, or 0~2.0KΩ/100.0KΩ on the high range, all measured 3-wire. Get the range wrong and the position reading won’t track correctly across the full travel.
In actual application, the CS2-PM does field calibration directly with your actual potentiometer – so it’s set to your specific valve, gate, or actuator’s real travel, not just a factory-generic scale. It comes with 4 relays (Hi/Lo/Hi Latch/Lo Latch/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. It’s commonly used for thickness measurement testing, and position control on valves and gates. CE and RoHS compliant.
From our experience, before we quote this, we would normally check your potentiometer’s resistance range, how many relays and what functions you need, and whether you need the analogue or RS-485 option. Hope this helps.
