SDJ-9L vibration transmitter

SDJ-9L vibration transmitterCompared to SG-2 typesensorUsed for measuring the vibration of bearing covers and bushings in rotating machinery. This transmitter has small size, high accuracy, and easy installation. The power supply of the transmitter is DC24V, which can be used for online measurement of vibration amplitude and intensity. The output standard current is 4-20mA, which is easy for users to connect to the computer DCS system. Users can choose according to their actual usage. If required by the user, our factory can provide AC220V to DC24V DC stabilized power supply.

3、 Installation and use
　　Vibration TransmitterIt should be installed in a clean, dry environment with an ambient temperature of -25~45 ℃ and no corrosive gas. Not suitable for installation in places with strong electric fields, strong magnetic interference, strong impacts or vibrations.SDJ-9L vibration transmitterInstalled on-siteinstrumentShielded cables must be used as connecting wires between sensors and transmitters in cabinets or junction boxes. Two core SBWP3 × 16/0.15 shielded cables (for reference only) can be used. Connect the positive (red) and negative (black) wires of the sensor to the input 1 and 2 terminals of the transmitter, and connect the other end of the shielded wire to the transmitter 3 terminal and the ground. The mesh shielding layer on one end of the sensor is floating. The 4-20mA current output of the transmitter corresponds to the full range.
