Description

PR6423/002-030-CN+CON021 Pre-Installation Preparation

1.1 Product and Package Inspection

Verify that the sensor model (PR6423/002-030-CN) matches the project specification.

Check for physical damage (e.g., cracked probe, damaged cable insulation, bent connector pins) and ensure all accessories are complete (mounting bracket, fixing bolts, washer, cable gland, user manual).

1.2 Environmental and Equipment Requirements

Confirm the installation location meets the sensor’s operating conditions:

Operating temperature: -40°C ~ +120°C (-40°F ~ +248°F)

Relative humidity: 0% ~ 100% (condensing allowed with proper protection)

Vibration resistance: Compliant with IEC 60068-2-6 (10~2000Hz, 10g acceleration)

Ensure the measured surface (rotating shaft) is clean, free of rust, oil stains, or scratches; the surface roughness should be Ra 0.8~3.2μm.

1.3 Tool and Material Preparation

Prepare tools: Torque wrench (range 0~20N·m), caliper (precision ±0.01mm), wire stripper, screwdriver set, anti-static wristband.

Prepare materials: Shielded twisted-pair cable (2-core/4-core, rated voltage ≥500V), cable gland (matching cable diameter), insulation tape, and grounding clamp.

PR6423/002-030-CN+CON021 Mounting Bracket Installation

2.1 Positioning the Bracket

Determine the installation position based on the machinery’s vibration monitoring points (typically radial vibration of the rotating shaft, 90° perpendicular to the shaft centerline).

Ensure the bracket is aligned with the shaft’s rotation center to avoid measurement errors caused by angular deviation.

2.2 Securing the Bracket

Fix the mounting bracket to the machinery’s stationary structure using the provided bolts.

Tighten the bolts with a torque wrench to the specified torque (8~12N·m); ensure the bracket is stable without looseness or deformation.

Verify that the bracket has no direct contact with rotating parts or high-temperature surfaces (minimum gap ≥5mm).

PR6423/002-030-CN+CON021 Sensor Probe Installation

3.1 Probe Assembly

Remove the protective cap from the sensor probe tip.

Screw the probe into the mounting bracket’s threaded hole by hand until it is in contact with the shaft surface (do not apply excessive force to avoid damaging the probe).

3.2 Air Gap Adjustment

Use a caliper to measure the air gap between the probe tip and the shaft surface (standard gap: 1.0±0.1mm; refer to the product nameplate for specific values).

Adjust the probe’s position by rotating it clockwise (reducing gap) or counterclockwise (increasing gap) until the required air gap is achieved.

Lock the probe with the lock nut using a torque wrench (locking torque: 5~7N·m); recheck the air gap after locking to ensure no deviation.

PR6423/002-030-CN+CON021 Cable Routing and Wiring

4.1 Cable Routing

Route the sensor’s signal cable away from power cables (minimum separation ≥10cm) to avoid electromagnetic interference.

Use cable glands to fix the cable at the bracket and junction box to prevent cable pulling or damage.

Avoid sharp bends in the cable (minimum bending radius ≥10×cable diameter) and ensure the cable is not stretched or compressed.

4.2 Wiring Connection

Turn off the power supply of the monitoring system before wiring.

Strip the cable insulation (length: 5~8mm) and connect the wires to the terminal block according to the wiring diagram:
Connect the cable’s shield layer to the system’s protective ground (single-point grounding, grounding resistance ≤4Ω) to enhance anti-interference performance.

Wrap the wiring terminals with insulation tape to prevent short circuits; tighten the terminal screws to ensure reliable contact.
