Specifications

Part Number: 21508-02-12-05-02
Manufacturer: Bently Nevada
Country of Manufacture: United States (USA))
Product Type: Probe Proximity Vibration
Series: Bently Nevada 3300

21508-02-12-05-02 is a Probe Proximity Vibration developed by Bently Nevada. It is a part of the Bently Nevada 7200 5mm / 8mm Series Proximity Transducer System. The Bently Nevada 7200 5mm / 8mm Series Proximity Transducer Systems are non-contacting, gap-to-voltage transducer systems that measure static and dynamic distances between the probe tip and the observed target.

Features

• The general use is any circumstance requiring an accurate, non-contact displacement measurement.
• However, the most prevalent application is for shaft position and vibration measurements on rotating and reciprocating machinery.
• They are intended for use with nearly any machine type, including gas and steam turbines, compressors, pumps, centrifuges, electric motors, and generators. The system has an 80 mil (2mm) linear measuring range and is API 670 compliant.

21508-02-12-05-02 Attributes

Input

• Power:-175 Vdc to-26 Vdc at 12 mA maximum consumption

Output

• Scale Factor: 200 mV/mil (7.87 V/mm), 4% (measured in increments of 10 mils over the calibrated range) if calibrated as a system. Within 29.5% including interchangeability errors.
• Linearity: Within 0.8 mils (0.02 mm) of a 200 mV/mil straight line if calibrated as a system. Within 2.3 mils (0.06 mm) of a 200 mV/mil straight line including interchangeability errors.
• Frequency Response: 0 to 10 kHz (0 to 600,000 cpm); -5% at 10 kHz
• Calibrated Range: 80 mils (2.0 mm). Begins at approximately 30 mil (0.25 mm) from probe face (600,000 cpm)
• Temperature Sensitivity: Typically-3% change in scale factor at +150 F (+65°C) at 50 mil gap (1.27 mm).

Environmental Limits

• Operating Temperature: -30°F to +350°F (-34°C to +177°C).
  Relative Humidity: To 95%, noncondensing
• Corrosion Resistance (for 8 mm probes only): Probe operation is not affected by direct contact to the following air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK (methyl ethylkeytone) or DMF (Dimethylfor mamide).
• System Weight: 1.3 lbs (0.59 kg).
