Professional Geophysical Instruments CBH-300 hydrophone tester Transmission

Fast detailed description:

The DB-ZD-A type vibration transducer can be measured relative to the shell or structure - i.e. vibration free space absolute vibration, especially for a bearing machine. Vibration in this machine shaft can be more to the casing, the transmitter coupled magnetoelectric vibration velocity sensor, continuous measurement and protection for rotating machinery.

The DB-ZD-A type vibration transducer signal input, output current and power supply three terminal isolation, greatly increasing its anti disturbance ability at the scene when the standard, the output 4 ~ 20mA current signal, can be directly sent to PLC, DCS monitor system.

Main function:
1Suitable for Bearing vibration measurement of rotating machinery
2Optional vibration intensity or vibration displacement monitoring

3Photoelectric isolation of 4 ~ 20mA analog output

4Vibration buffer output, convenient to use other vibration analysis system
