Solartron Metrology 922940 变压器
Solartron Metrology Analogue Sensor, ±2.5mm stroke -20°C +80°C
Solartron Metrology
Miniature dc Energised With built-in electronic oscillator and demodulator producing an dc output proportional to core positionDFg series; have separate coil/electronic assemblies with a free core fitted with a polyacetal homopolymer bearing which can rub on the inside coil assembly to ease guiding requirementsDG2.5; This has a non-rotating spring-loaded armature running in precision linear ball bearings Output Ripple Temp. Coefficients (°C) DFg1; Others Cable 3m PVC Screened Operating Temp. (°C) -20 to +80 Non-Linearity 0.3% Linear Variable Differential Transformers (LVDT) These devices comprise a movable nickel iron core and three coils - one for energisation and two for pick-up. They need to be driven by a sine wave to produce an output amplitude and phase directly proportional to the position of the core with respect to the pick-up coils. A phase sensitive detector is required to demodulate the output signal. The main advantages of LVDTs are; No wear problems as with potentiometersInfinite resolution, high accuracy and linearityNo friction introduced into the measured systemAvailable in ranges from ±1mm to ±50mm 注 RS LVDT's datasheet Stock No. 232-4049 is available on request. ; Stroke ±2.5mm; Input Current Range 10 mA; Energising Voltage Range 10 → 24 V dc; Sensitivity 750 mV/mm @ 10 V dc; Response Time 3 ms; Overall Height 1mm; Overall Width 94mm; Minimum Operating Temperature -20°C; Maximum Operating Temperature +80°C;
