Vibro-Meter IQS450 S3960 204-450-000-002-A1-B23-H5-I0 Eddy Current Signal Conditioner

Description

The Vibro-Meter IQS450 S3960 204-450-000-002-A1-B23-H5-I0 is an eddy-current signal conditioner designed to work with the TQ42x proximity transducer and EA402 extension cable for accurate non-contact measurement of shaft vibration, axial position, and displacement in rotating machinery. It provides the excitation signal required by the transducer and converts the measured gap into a stable analog output for machinery protection and condition monitoring systems. This version offers a 4 mm linear measuring range, 4 mV/μm sensitivity, DC to 20 kHz frequency response, and a 5 m system length, making it suitable for continuous monitoring of critical equipment such as steam turbines, gas turbines, compressors, pumps, and generators.
