We had an enquiry from a customer who needed a panel conditioner for a potentiometer input – reading position or level from a potentiometer sensor and getting an analogue output with relay alarms. The ADtek ST-PM covers this, plugging into the same 11-pin socket as the rest of ADtek’s ST series.
This looks simple, but potentiometer conditioning still needs some checking. The ST-PM measures 0~50Ω/2.0KΩ or 0~2.0KΩ/100.0KΩ (3-wire), with ±0.04% accuracy – so we would need your potentiometer’s resistance range before quoting. It also supports field calibration directly with the potentiometer, so you can set it up on site without lab equipment.
In actual application, the ST-PM gives you 1 analogue output, 1 RS-485 port, 3 relay outputs, and an excitation supply output, with cross-selection allowing up to 3 of these active at once. It’s user-programmable from the front panel. CE approved.
From our experience, before we quote this, we would normally check your potentiometer’s resistance range (0~50Ω/2.0KΩ or 0~2.0KΩ/100.0KΩ), and which combination of analogue output, RS-485, relay, and excitation supply you need active. Hope this helps.
