Technical Specifications Sensor type: 3-wire LVDT; Range: ±5 mm to ±100 mm selectable; Output: 4–20 mA two-wire; Supply: 18–32 V DC; Accuracy: ±0.25% FS; Operating temperature: -40 °C to +85 °C; Enclosure: IP40.
Functional Features Integrated LVDT excitation source; adjustable zero and span; open / short circuit detection; reverse polarity protection; low temperature drift design.
Application Scenarios Actuator position feedback, valve position indication, oil motor stroke monitoring, linear displacement closed-loop control.
Performance Parameters Linearity: ±0.25% FS; Temperature drift: < 0.01% per °C; Response time: < 5 ms; Ripple: < 10 µA.
Material Composition Industrial plastic housing; precision analog circuit; LVDT excitation stage; V/I output stage.
Structural Characteristics DIN rail mountable; front zero/span adjustment potentiometers; status LED; rear terminal block.
Working Principle Supplies excitation to the LVDT primary winding, detects the differential voltage from the secondary winding, demodulates to a DC signal proportional to displacement, and converts it to a standard 4–20 mA current output.
