Ordinary integrated vibration transmitter
The integrated vibration transmitter integrates the vibration sensor circuit with the precision measurement circuit, realizes the measurement and transmission function of "sensor + detection instrument", and establishes a high-precision vibration measurement system. It outputs 4-20mA signal and can be directly connected to DCS, PLC or other systems. It is an ideal choice for vibration status monitoring of industrial rotating machinery gears and bearings such as fans, turbines, compressors, and water pumps.

7. Structure and working principle
The transmitter consists of a piezoelectric circuit, a signal processing board, a terminal block and a housing. The piezoelectric probe detects the vibration of the object being tested and converts the acceleration of the vibration of the object being tested into a corresponding piezoelectric signal. The signal is processed by the integration and amplification circuit to output a current signal of 4 to 20 mA.
The transmitter is made into a flameproof electrical device according to GB3836.1-2016 and GB3836.2-2016, or a dust explosion-proof type according to GB12476.1-2013 "Electrical Equipment for Combustible Dust Environment Part 1: General Requirements". The explosion-proof mark is Exd‖CT6 Gb or ExtDA21 IP66 T80℃
The maximum surface temperature of the equipment housing does not exceed 80℃.
The flameproof surface of the equipment complies with the provisions of Article 5.3 of GB3836.2.
The cable entry device can withstand the tightening test specified in Appendix A of GB3836.1.
The sealing and mechanical strength of the cable entry device meet the requirements of Appendix C of GB3836.1.
The transmitter has internal grounding and is fixed on the metal equipment housing.
The product has a beautiful and symmetrical appearance.
8. Installation and wiring
Correctly install the vibration sensor on the object to be measured. Generally, one end of the stud screw provided by the manufacturer is fixed to the center hole of the transmitter base, and the other end is fixed to the appropriate position of the bearing cover of the rotating machinery. The installation thread is M10×1.5. To eliminate on-site interference, one end of the shielded cable must be grounded.
