Based on the theory of differential transformer, differential transformer displacement sensor which is composed of oscillator, differential transformer, phase-sensitive demodulator sealed in stainless, nonmagnetic case can convert linear mechanical signal to electric signal. The sensors is applicable to measure displacement and those converted to displacement such as stretch, expansion, strain, pressure.
There are 3 kinds of differential displacement sensors: QSY9701、QSY9704－separated iron core；QSY9702、QSY9705 series－core guiding；QSY9703、QSY9706－guiding springback Technical Data Type | QSY9701、9702、9703 DC Differential Displacement Sensor | Operating Temperature | -25℃~+70℃ | Relative Humidity | ≤85%，25℃ | Loading | 20KΩ | Ripple | <1%, Typical value 0.5% | Source Voltage | DC9~15V(<50mA) | Thermal Zero Drift | 0.015%/℃ | Linearity | 0.1%,0.2%,0.3%,0.5%F.S | Full Range Temperature Drift | 0.02%/℃ | Max.
