TQ912 111-912-000-011 A1-B6-E5000-F2-G4800-H05

Product Overview

The TQ912 is a high-performance, non-contact proximity sensor in the Vibra-Meter ® product line of Parker Meggitt, specifically designed for reverse-mounted applications. It operates based on the eddy current principle and is used to precisely measure the relative displacement between the sensor probe and the metal target. This sensor is usually used in combination with the EA902 extension cable and the IQS900 signal conditioner to form a complete, calibrated proximity measurement chain.

The specific model 111-912-000-011-A1-B6-E5000-F2-G4800-H05 introduced this time integrates a 5-meter-long body cable and is equipped with a flexible stainless steel sheath for protection. It is suitable for standard (non-explosion-proof) industrial environments and is an ideal choice for the protection and condition monitoring of rotating machinery.
