Velocity Transducer Systems - 9200 and 74712

Velocity Transducer

These are 2-wire, moving-coil velocity transducers, designed for general purpose velocity measurements. For most applications, however, we recommend the use of our Velomitor® piezo-velocity sensors.

 

 

 

 

 

 

9200 and 74712 Seismoprobe Velocity Transducers

Specifications are at approximately +22°C (+72°F) with 25 mm/s (1 in/s) of machine casing vibration at 100 Hz (6000 cpm) with a 10 kilo ohm load unless otherwise specified.

Electrical

Sensitivity 20 mV/mm/s (500 mV/in/s), ±5% when properly terminated and oriented at the angle of calibration
Frequency Response From minimum operating frequency (see ordering information) to 1 kHz (60,000 cpm); +0, -3dB typical.
Dynamic Operating Range 2.54 mm (0.100 in) peak to peak maximum displacement.
Shock Resistance Withstands 50 g peak maximum acceleration along nonsensitive axis.
Transverse Sensitivity ±10% maximum.
Polarity of Output Signal Pin A goes positive with respect to Pin B when the transducer case velocity is towards the connector.
Leadwire Length 305 metres (1,000 feet) maximum between Seismoprobe Velocity Transducer and 3300 or 3500 Monitor. Consult manual for frequency roll-off at longer lengths.
