Common types of resistive resistive sensor is to be measured, such as displacement, deformation, force, acceleration, humidity, temperature, etc. These quantities converted into a resistance value of formula such a device. There are resistance strain, piezoresistive, thermal resistance, thermal, gas, humidity and other resistive sensors. Frequency power inverter power sensor by voltage and current input signal sampling quality filter sensor to communicate, and then enter the second instrument samples connected by transmission system with digital cable, optical fiber, digital input voltage secondary instrument sampling filter calculates the value of the current sensor supplier, you can get the voltage rms, current rms, fundamental voltage and fundamental current, voltage harmonics, harmonic current, active power, fundamental power, harmonic power other parameters. Capacitive level sensor consists of a capacitive sensor and an electronic module circuit, it is a two-wire 4 ~ 20mA constant current output for the base model, through the conversion filter sensor, you can use three-wire or four-wire sensor supply output filter The output signal is formed as 1 ~ 5V, 0 ~ 5V, 0 ~ 10mA signal standards. Capacitive sensor consists of insulated electrodes and cylindrical metal container with measuring the composition of the medium. When the material level rises, due to the dielectric constant of the non-conductive material is significantly less than dielectric constant of air, so that the capacitance of the material change with altitude changes. Module circuit sensor consists of a reference source, pulse width modulation, conversion, constant amplification, feedback and current limiting unit. The advantage of using the principle of pulse width modulation characteristics are measured at lower frequencies, radio frequency interference on the surrounding element, good stability, good linearity, no significant temperature drift.
