II. Electrical Performance Parameters

Measurement Range: Linear range 4mm (160mil), suitable for high-temperature unit radial vibration, axial thrust, and differential expansion monitoring

Standard Sensitivity: 7.87V/mm (200mV/mil), factory-calibrated, no field calibration required

Frequency Response Range: DC to 10kHz, covering the conventional vibration frequency range of steam turbines and gas turbines

Cable Electrical Characteristics: Extension cable impedance 75Ω, capacitance 69.9pF per meter; 9 The entire system impedance and capacitors are factory-matched.

Connection Interface: ClickLoc miniature coaxial quick-lock connector, stainless steel connector material. Recommended torque for mating is to tighten by hand and then rotate 1/8 turn.

Matching: Must be paired with a high-temperature preamplifier of the same total length (replacement model 330380-90-00, the original 330300 is discontinued).

III. Mechanical Structure and Materials

Probe Sensing Terminal: Sealed ceramic material, hermetically sealed, waterproof, oily, and impurity resistant.

Probe Housing: AISI 316L stainless steel, high temperature and corrosion resistant.

Rigid Hardwire Cable: AISI 304L stainless steel sheath, fixed length 1 meter.

Extension Cable: FEP insulated triaxial cable, with stainless steel armor protection.

Installation Thread: Standard 3/4-16 UNF external thread.

Maximum Installation Tightening Torque: Probe housing 81 N·m (720 in·lb)

Mechanical Tensile Strength Withstand: Maximum tensile strength at the probe and extension cable connection point 289 N (65 mm). (lbs)

Minimum bending radius: Minimum cable bending radius 25.4mm (1 inch)

Weight reference: Hard wire cable 117g per meter, probe housing 12g per centimeter; total transport weight of 9 meters including armor is approximately 2.5kg

IV. Temperature environmental tolerance

Probe body (including 1 meter hard wire): Unified operating and storage temperature range -34℃ ~ +350℃, capable of continuous operation at 350℃ for extended periods.

Armored extension cable: Operating temperature -52℃ ~ +177℃

Matching high-temperature preamplifier 330380-90-00: Operating temperature -52℃~+100℃, storage temperature -52℃~+105℃, preamplifier aluminum shell with epoxy powder coating protection

Humidity tolerance: Stable operation in environments with up to 95% condensation resistance

Interference protection: Excellent RFI/EMI protection Radio frequency electromagnetic interference immunity; single-point shielded grounding is recommended.

V. Application Scenarios and Basic Information

Applicable Equipment: Gas turbines, steam turbine high-temperature sealed areas, bearing high-temperature measuring points, interstage clearance, rotor mid-span vibration mode monitoring, differential expansion axial displacement measurement

Factory Configuration: Probe + 1 meter stainless steel hard wire + 8 meter armored extension cable. The entire set is factory-calibrated and cannot be arbitrarily disassembled or mixed with preamplifiers of different lengths.

Warranty: Original factory standard 12-month warranty

Origin: Manufactured in Bently Nevada, a subsidiary of Baker Hughes, USA

Explosion-proof Certification: This model does not have explosion-proof certification (code 00). For explosion-proof applications, a model with a certification code must be used.

VI. Usage Restrictions

The total length of the entire set is strictly limited to 9 meters. Do not cut or splice the cable on-site, as this will damage the factory-installed capacitance impedance matching and directly cause sensitivity drift and measurement failure. Ceramic terminals must not be impacted or bumped; damage will result in loss of airtightness and high-temperature resistance. Avoid cutting the sheath with sharp edges when laying armored cables; do not allow direct contact with high-temperature pipe walls for baking in high-temperature areas. Only compatible with 3300 XL high-temperature series preamplifiers; cannot be used with standard 8mm/5mm preamplifiers at room temperature.
