Question

Answer

What is the primary function of the TQ402 111-402-000-013 transducer?

Its main function is to measure shaft displacement and vibration in rotating machinery (like turbines, compressors, and pumps) without making physical contact. It uses eddy current technology to provide accurate, real-time data for condition monitoring and protection systems.

What types of connectors does the TQ402 111-402-000-013 use?

The integral cable is terminated with a self-locking miniature coaxial connector. This connects to the extension cable or the signal conditioner and is designed to be hand-tightened until it locks.

Can the TQ402 111-402-000-013 be used in high-temperature environments?

Yes. According to the official datasheet, the transducer tip is rated for continuous operation from -40 to +180°C. It can survive short-term exposure up to +220°C, though with increased drift. The integral cable is rated for up to +200°C.
