Eddy-Current Probe Scaling & Rotor Dynamics

The transducer utilizes high-frequency radio-frequency electromagnetic fields to acquire radial vibration and axial position metrics relative to the probe tip. Output scaling maintains a strict linear sensitivity of 3.94 V/mm across the measurement envelope. During system alignment, gap voltage validation must confirm a nominal -10 VDC reading at mid-stroke position to prevent signal clipping during severe transient rotor vibration. Robust coaxial shielding prevents cross-talk across multi-channel monitor racks.

Ordering Information and Delivery Content

• 1 x 3300 XL 11 mm Proximity Probe Assembly with 5.0 m Armored Coaxial Cable
• 1 x M14 x 1.5 Threaded Locknut with Safety Wire Holes
• 1 x Protective Terminal Cap

Mechanical Installation and Routing Guidelines

• Thread and Torque: Utilize the M14 x 1.5 metric threads for mounting, tightening the probe casing to a recommended torque of 21.1 N m (187 in lb).
• Safety Wire Locking: After establishing the gap voltage, thread safety wire through the 1.59 mm diameter locknut holes to prevent loosening under high machinery vibration.
• Cable Bending Limits: Maintain a strict minimum bend radius of 25.4 mm (1.0 in) along the armored lead to prevent internal conductor degradation.
• Conduit Routing: Route the armored cable through dedicated instrument pathways, keeping absolute physical separation from high-voltage motor feeds.

Frequently Asked Questions and Technical Responses

• What output sensitivity does this 11 mm proximity transducer provide?

  The probe delivers a calibrated output sensitivity of 3.94 V/mm or 100 mV/mil when matched with its companion proximitor.

• What thread size and armor configuration does this specific part number use?

  It features an M14 x 1.5 metric mounting thread combined with integrated stainless steel cable armor.

• What is the total system cable length specified by the 50 suffix code?

  The 50 suffix designates a total system electrical cable length of 5.0 meters or 16.4 feet.

• How is the baseline gap voltage verified during sensor commissioning?

  A digital voltmeter is connected across the monitor common and voltage terminals to verify the -10 VDC target.

• What is the recommended tightening torque for the M14 probe body?

  The probe housing must be torqued to precisely 21.1 N m (187 in lb) during installation.

• Are standard ClickLoc connectors utilized on this probe assembly?

  Yes, gold-plated brass ClickLoc connectors lock securely to prevent vibration-induced decoupling.

• What is the minimum allowable bend radius for the probe cable?

  The cable must maintain a minimum bend radius of 25.4 mm (1.0 in) to protect internal integrity.

• Can this transducer system be integrated directly with legacy 7200 series monitors?

  No, upgrading to 3300 XL 11 mm components requires matching 3300 XL proximitors and updated monitoring system software.
