Intrinsically Safe Vibration Acceleration Transducer adopts built-in integrated circuit amplifier. The signal conditioning module, which is connected with the transducer by mining flame-retardant cable, is used to modulate vibration signals. According to the mine electrical products intrinsically safe electrical requirements, design the intrinsically safe power supply module on signal conditioning board. The power of the vibration acceleration transducer is supplied though signal conditioning module which is powered by a intrinsically safe power. The intrinsic parameters of apparatus in intrinsically safe test measured are as follows: the intrinsically safe voltage DC21V, intrinsically safe current 65mA, intrinsically safe capacitance 0 u F, intrinsically safe inductance 0mH.The co
