I. Model Explanation (330195-02-12-10-00)

330195: 8mm ETR reverse-mounted probe, 3/8-24 UNF thread

02: Threadless length = 0.2 inches (5mm)

12: Shell total length = 1.2 inches (30mm)

10: System total length = 1.0 meter (probe + built-in cable)

00: No explosion-proof / No special certification (standard)

Reverse Mount: Thread at the root, probe extends outward from the inner side of the mounting surface, suitable for locations with narrow space and where traditional forward mounting cannot be installed.

II. Core Parameters (Electrical / Mechanical / Temperature)

Electrical (Standard 8mm XL)

Sensitivity: 7.87 mV/μm (200 mV/mil)

Linear range: 0.25 - 2.3mm (10 - 90 mil)

Frequency response: 0 - 10kHz (±3dB)

Impedance: 75Ω (standard, not 300Ω)

Target surface: 4140 steel (default) Mechanical

Thread: 3/8-24 UNF external thread (reverse installation)

Shell: 316L stainless steel

End: Polyimide (temperature resistant)

Cable: ETR high-temperature cable, 1m integrated

Installation torque: ≤ 27 N·m (240 in-lb)

Temperature (ETR extended temperature, critical)

Operating temperature: -40℃ ～ +218℃ (425°F)

Standard 8mm probe: Maximum +177℃; This model is 41℃ higher

Storage temperature: -55℃ ～ +240℃

III. Standard Accessories (75Ω System)

Probe: 330195-02-12-10-00 (1m, reverse, ETR)

Preamplifier: 330180-01-00 (1m calibration, panel / DIN)

Extension cable: 330130-010-00 (1m, ETR, optional)

Monitoring card: 3500/40 (vibration), 3500/42 (displacement)

⚠️ Cannot be used with 300Ω (33028x series), must be 75Ω matched.

IV. Typical Applications (Reverse + High Temperature)

Gas turbine: High-temperature bearing box, exhaust section vibration / displacement (180～210℃)

Steam turbine: Inter-stage seal, narrow cavity (forward installation without space)

Industrial compressor: High-temperature shell, axial movement (≥180℃)

High-speed pump / fan: Compact bearing housing, reverse installation requirement

ETR scenario: Cable / probe long-term > 177℃, but < 218℃

V. Difference from Ordinary 8mm Probe (330104) Table

Parameters: 

330195 (Reverse ETR) - 330104 (Standard Assembly)

Installation method: Reverse (Inner side → Outer side) - Standard (Outer side → Inner side)

Thread: 3/8-24 UNF - M10×1

Maximum temperature: 218℃ (ETR) - 177℃ (Standard)

Cable: ETR High Temperature (260℃) - Standard (177℃)

Length: 1m (Fixed) - 5/9/14m Optional

Price: Approximately 25% - 30% higher than standard

Six. Selection Tips
