PA150 800-150-000-011

PA150 800-150-000-011 is a probe mounting adapter that integrates a proximity measurement chain into a complete, standalone system designed for the non-contact measurement of rotating machinery shafts in demanding industrial environments.

• Measurement principle: Eddy current (non-contact)
• Linear measurement range (G3): 0.3 ~ 4.3 mm
• Sensitivity (G3): 4 mV/μm (voltage) / 1.25 μA/μm (current)
• Frequency response: DC ~ 20 kHz (-3 dB)
• Linearity: Refer to performance curve
• Total system length: 1 m (TQ912 integrated cable)
• Sensor temperature range: -40°C ~ +180°C
• Signal conditioner temperature range: -40°C ~ +85°C
• Housing protection rating: IP65
• Housing material: Aluminum alloy (die-cast)
• Mounting rod material: Stainless steel 1.4301
• Adapter material: Stainless steel 1.4305
• Explosion-proof certification: Ex e (Increased Safety)
• EMC compliance: EN 61000-6-2 / EN 61000-6-4
• Electrical safety: EN/IEC 61010-1

The PA150 combines the sensor, signal conditioner, and mounting structure into a single unit, significantly simplifying installation and commissioning. Key features include a 4 mm linear measurement range (G3 sensitivity: 4 mV/μm), a wide frequency response (DC to 20 kHz), SIL 2 functional safety certification, and API 670 compliance.

Its detachable housing design allows for gap adjustments while the machine is running, while the stainless steel mounting rod (available in lengths from 50 to 800 mm) and ±10 mm position adjustment capability offer exceptional installation flexibility.

The PA150 is widely used for vibration protection and condition monitoring of rotating machinery—such as steam turbines, gas turbines, compressors, and pump sets—in sectors including power generation and petrochemicals. Its IP65 ingress protection rating and wide operating temperature range ensure long-term, reliable operation in harsh industrial environments.

A petrochemical enterprise required monitoring of rotor axial displacement for a centrifugal compressor to prevent thrust bearing damage. The PA150's 4mm linear measurement range (G3 option) covers the full span of axial displacement.

A stainless steel mounting rod (C144, 144mm) and adapter assembly (E105, 105mm) provide flexible adjustment of the mounting depth (±10mm). The voltage output signal (-1.6V to -17.6V) is fed into the VM600 monitoring system to enable real-time position monitoring and alarming.

The mounting position of the stainless steel probe stem is adjustable within a ±10 mm range, and the adapter offers various thread and length options to suit different mounting surfaces:

• External Installation: Supports reverse mounting of the TQ912 sensor, allowing installation without dismantling the machine.
• Gap Adjustment: The detachable housing design enables easy adjustment of the gap between the probe and the target, even while the machine is running.
• Flexible Mounting: The mounting position of the stainless steel probe stem is adjustable within a ±10 mm range, and the adapter offers various thread and length options to suit different mounting surfaces.

What is the measurement principle of the PA150?
The PA150 utilizes the eddy-current principle for non-contact measurement.

Can it be used in hazardous areas?
Yes. The PA150 is available in an explosion-proof (Ex) certified version (model code A5) suitable for potentially explosive environments. However, please note that all components of the entire measurement chain (sensor, cable, and signal conditioner) must possess the corresponding Ex certification.

What is the total system length?
For the PA150, the total system length (TSL) corresponds to the length of the 1-meter integrated cable attached to the TQ912 sensor.

What is the warranty period?
Standard industrial warranty: 12 months; with proper installation and no overloading, the product has a service life of 5-10 years.
