Engineering Advantages
Extended Temperature Performance (ETR)
Supports operation up to +260°C, making it suitable for high-temperature environments such as steam turbines and combustion systems where standard probes may fail.
Simplified Reverse-Mount Installation
Allows installation from the exterior of the machine housing through a threaded port, reducing downtime and eliminating the need for internal access.
Stable Measurement Accuracy
Maintains a consistent 200 mV/mil scale factor across a wide temperature range, ensuring accurate vibration and position readings with minimal thermal drift.
Chemical and Corrosion Resistance
The PPS probe tip resists degradation from harsh chemicals, lubricants, and gases, ensuring long-term durability in aggressive operating environments.
FAQs
Does this probe require a specific extension cable?
Yes. A 3300 XL ETR extension cable must be used, and the total system length must match the calibrated Proximitor length.
Is it compatible with standard 330105 reverse mount probes?
It is physically compatible in many cases, but it should be paired with an ETR-calibrated Proximitor to ensure accurate performance at elevated temperatures.
What does the “-CN” suffix indicate?
It indicates compliance with Chinese hazardous area standards (GB/T), suitable for use in certified intrinsic safety (IS) systems in explosive environments.
How is proper gapping performed?
Gap is typically set by monitoring the Proximitor output voltage (commonly targeting around -10 VDC) or using a dial indicator to achieve the correct mechanical clearance.
