190501 Velomitor* CT Velocity Transducer

Description
The Velomitor* CT Velocity Transducer is a low-frequency version of our standard Velomitor Piezo-velocity Sensor. Its design specifically measures casing vibration velocity on cooling tower and air-cooled heat-exchanger fan assemblies that operate at or above 90 rpm (100 to 300 rpm typical). The Velomitor CT Transducer can measure vibration amplitudes at these frequencies as well as the vibration frequencies generated by the fan motor and speed reducer.
Specifications
Parameters are specified from +20 C to +30 C (+68 F to +86 F) and 100 Hz unless otherwise indicated.
Electrical
Sensitivity
3.94 mV/mm/s (100 mV/in/s) ±5%.
Frequency Response
3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB ；1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB
Temperature Sensitivity
-8% to +5% typical over the operating temperature range.
Velocity Range
63.5 mm/s pk (2.5 in/s pk)  Vibration components in excess of 10g pk，above 1 kHz can significantly，reduce this range.
Transverse Response
Less than 5% of the axial sensitivity.
Amplitude Linearity
±2% to 63.5 mm/s pk (2.5 in/s pk)
Mounted Resonant Frequency
9 kHz, minimum (stud mounted, except quick disconnect)
Output Bias Voltage
10.1 Vdc±1.0 Vdc , Pin A referenced to Pin B
Dynamic Output Impedance
<400 Ω typical
Broadband Noise Floor (1.5 Hz to 1 kHz)
0.229 mm/s (0.009 in/s) pk. See Figure 6 for typical noise floor.
Base Strain Sensitivity
0.43 mm/s/μstrain (0.017 in/s/μstrain).
Grounding
Internal electronics are isolated from case.
Maximum Cable Length
305 metres (1,000 feet) of cable (part number 02173006) with no degradation of signal. Note: Maximum continuous length of cable available is 300 feet. If longer lengths are required they must be spliced or have a connector installed on them.

Environmental Limits
Operating Temperature
-40 C to +85 C (-40 F to +185 F).
Storage Temperature
-40 C to +100 C (-40 F to +212 F).
Shock Limit
5000 g pk, maximum.
Humidity Limit
100% condensing, non-submerged.
Magnetic Field Susceptibility
<0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60Hz
