21504-00-12-05-02 Bently Nevada Proximitor | 2mm Range

Introducing the Bently Nevada 21504-00-12-05-02 Proximity Probe System

Key Technical Specifications of the 21504-00-12-05-02

• The 21504-00-12-05-02 operates with a supply voltage ranging from -17.5 to -26 V DC. It draws a maximum current of just 12 mA, ensuring minimal power consumption.
• This system provides a calibrated measurement range of 2.0 mm (80 mils). The linear sensing starts at only 0.25 mm from the unthreaded probe tip surface.
• It features a precise output sensitivity of 200 mV/mil (7.87 V/mm) with a ±4% system-calibrated scale factor. System-calibrated linearity is ±0.02 mm typical.
• The frequency response covers from 0 to 10 kHz, suitable for capturing essential vibration data from high-speed machinery. This bandwidth effectively monitors up to 600,000 CPM with only -5% at 10 kHz.
• Suffix configuration 00 specifies an unthreaded tip, while 12 designates a 120 mm (4.72 inch) case length. The 05 suffix confirms a 0.5 meter (20 inch) cable, and 02 indicates a miniature coaxial male connector.

Physical Build and Environmental Resistance

• The probe tip features an 8 mm diameter standard housing with a 3/8-24 thread for easy and secure mounting. This version includes no lead armor for standard industrial applications.
• This sensor withstands harsh industrial environments with humidity tolerance up to 95%. It offers corrosion-proof operation in oil, 10% acid, water, MEK, and DMF chemicals.
• The robust design ensures excellent immunity to radio frequency and electromagnetic interference. This stability guarantees consistent readings even in electrically noisy plant environments.
• Operating temperature for the probe extends from -34°C to +177°C. The proximitor electronics function reliably in temperatures from -51°C to +100°C.

Frequently Asked Questions (FAQ)

• What is the total accuracy with interchangeability for the 21504-00-12-05-02?
  The system provides ±9.5% total accuracy when using interchanged components. System-calibrated accuracy remains tighter at ±4% with matched components.
