GSZ65 voice Mine intrinsically safe sensor

GSZ65 Mine intrinsically safe sensor voice voice sensor uses the product is sound signal control device sensing device, a sensor head using imported components, also features sensitivity adjustment, delay adjustment, is the preferred equipment acoustic signal control equipment. Features Voice sensor is the use of audio sensing element properties of the produced voice detection and signaling equipment. When the detected ambient noise signal reaches a certain intensity, the sensor processing of the received signal, the audio signal is converted into an electrical signal output, enabling voice features. The main technical parameters 1, the working voltage: 12VDC 2, Working current: ≤30mA 3, the control signal output: controls the sound when the high level signal ≥6V no control sound signal high 4, the maximum input voltage ≤0.5 of: 12.5V 5, maximum input current: 515mA 6, measuring range 65db (A) -140db (A) 7, the maximum internal inductance Li 0mH 8, the maximum internal capacitance Ci 2.2uf 9, the weight of about 1Kg 10, Dimensions 147mm * 68mm
