Présentation du produit
The Epro PR9350/04 Inductive Sensor is a robust, non-contact proximity sensor designed to detect metallic objects in demanding industrial environments. This sensor is part sur Epro’s proven PR9350 series, which has been widely adopted in critical rotating machinery protection systems, such as turbines, compressors, and generators.
The PR9350/04 is especially engineered to monitor rotational speed and key phase signals. It is frequently used for phase reference measurements, such as detecting a once-per-turn event for vibration monitoring systems. Its rugged stainless steel construction, excellent electromagnetic compatibility, and wide temperature tolerance make it highly dependable for long-term field use.
The sensor operates on the inductive principle, using a built-in coil and oscillator to detect changes in metal proximity. With fast response times, immunitéy to oil and dirt, and compatibility with high-speed rotating equipment, the PR9350/04 plays a vital role in many predictive maintenance and condition monitoring applications.

Questions fréquentes (FAQ)
-
What is the main purpose sur the PR9350/04 sensor?
It’s mainly used to detect metal parts passing by, surten to track rotation or movement in machinery for monitoring or control. -
Can this sensor detect any metal object?
It works best with ferrous metals like steel. Non-ferrous metals may not be detected reliably. -
How close does the target need to be for detection?
Typically, the sensor detects objects within about 2 millimeters, depending on the size sur the target. -
What kind sur signal does the sensor send out?
It outputs a simple pulse signal each time a metal object is detected, which equipment can use for counting or timing. -
Is the sensor easy to install?
Yes, it screws in with a standard M16 thread, making it easy to mount securely and precisely. -
Will oil or dust affect the sensor’s performance?
Not really. It’s sealed with an IP67 rating, so it’s protected against dust and temporary immersion in water or oil splashes. -
Can it be used on very fast rotating equipment?
Yes, it can handle detection frequencies up to 20 kHz, suitable for high-speed machinery. -
What happens if the sensor doesn’t detect a target when it should?
The system relying on the sensor can be set to trigger an alert or take safety action if pulses stop unexpectedly. -
Does the sensor need to be calibrated regularly?
Usually not. Once it’s installed and positioned correctly, it keeps working reliably without much adjustment. -
Is this sensor safe to use in explosive environments?
It can be, but only if you choose the version that has the proper ATEX certification for hazardous locations.
