Velocity Transducer Systems - 9200 and 74712
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.
|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.|
