KPM12J 15-300mm Linear Potentiometer Displacement Transducer Resistance gauge Travel Sensor With Two Sides Ball Joint

Electrical principle: In this sample, all sensors are absolute position measurement type, used in the adjustment system and measurement system, direct measurement of displacement and length, output DC voltage signal, can also be converted into standard 0-5V, 0-10V, 4-20mA DC signal, RS485 digital signal through the built-in or external V/1 conversion module. It can meet the requirements of long-distance transmission control.

Electrical schematics: Potentiometer principle, 0-100% given input voltage (varies with displacement)

All sensor housing: anodized aluminum alloy, surface are electrophoretic anti-static and radiation treatment, high wear-resistant engineering slip ring, to ensure smooth operation. Part of the housing is stainless steel.

The conductive materials inside the sensor are imported advanced raw materials to ensure the high wear resistance and stability of the sensor, and the sensor can work reliably even under the worst conditions.

The buffer universal joint at the front of the sensor can overcome some of the misalignment tilt and vibration of the transmission rod.

Signal conversion specification

Ordinary electronic ruler and rope ruler, resistance type, are the displacement sensor of the principle of potentiometer, in fact, it is equivalent to a potentiometer, popular point also called: sliding rheostat, power supply how many V voltage, the output is 0-how many V voltage; That is, if the customer supply voltage is 5V, the output is directly 0-5V. If the supply voltage is 10V, the output is 0-10V. If the power supply is 3.3V, the output is 0-3.3V. If the power supply is 3.6V, the output is 0-3.6V. If the supply voltage is 24V, the output is 0-24V.

If the supply voltage is only 24V, there is no 5V or 10V power supply, but the output wants 0-5V or 0-10V, it needs to be equipped with our module. If the customer needs 4-20MA output, it must be equipped with modules. The module can be built inside the sensor, or can be a separate aluminum alloy or plastic shell module, at this time the direct power supply voltage to the module can be 15-36V, the output can be an external plug module, is 0-5V, 0-10V, 4-20MA, -10V-+10V, -5V-+5V, etc
