I. Model Positioning

330980: High-temperature-specific phase and speed probe, not compatible with conventional vibration probes

71: Side-out narrow-body structure, suitable for narrow installation spaces

00: The body does not come with a built-in cable, and it needs to be used in conjunction with an extension cable

Usage: For the high-temperature shell areas of steam turbines and gas turbines, only for phase picking and speed monitoring, not applicable for shaft vibration and displacement measurement

III. Installation Tips

1. Installation Gap

Standard installation gap: 1.0~1.5mm

Preferred material for the measured object: 4140 steel, the detection surface area is more than three times the diameter of the probe

Leave 5mm or more clearance around the probe to avoid metal interference

2. Wiring Standards

Three-wire wiring, the core wire is the signal end, the inner shield is the common end, and the outer shield is the grounding end

Shielded wire is only grounded on one side of the preamplifier to eliminate circulating interference

3. Installation Steps

Clean the installation hole and impurities on the measured surface

Insert the probe contact end face and retract 1.25mm as the standard spacing

Lock the anti-loosening nut, and the tightening torque is controlled at 8~10N・m

Straighten the wiring, the bending radius of the cable is not less than 25mm

IV. Common Faults

No pulse output: Check the installation gap, power supply line, wiring terminals, and cable continuity

Signal fluctuation and noise: Check the grounding method, whether the cable is close to strong electrical equipment

High-temperature signal abnormality: Confirm the probe working temperature, installation tightness, and detection spacing

V. Comparison of the Same Model

330980-71-00: No built-in cable, select the extension cable as needed

330980-71-05: Comes with 5m built-in cable, can be directly connected to the preamplifier on site

The structural temperature tolerance, electrical parameters, and adapter accessories are completely the same as the above two models
