Frequently asked questions

Q:What is the Vibro-Meter IQS450 S3960 204-450-000-002-A1-B21-H5-I0?
A:The Vibro-Meter IQS450 S3960 204-450-000-002-A1-B21-H5-I0 is an eddy-current signal conditioner designed to operate with a TQ42x proximity transducer and EA402 extension cable for non-contact shaft vibration, position, and displacement measurement.

Q:What measurement applications is the IQS450 suitable for?
A:It is used for shaft relative vibration, axial position (thrust), radial displacement, shaft eccentricity, and gap measurement on rotating machinery.

Q:What measuring range does this configuration provide?
A:This configuration provides a 2 mm linear measuring range with a nominal sensitivity of 8 mV/μm when used with the specified transducer system.

Q:What is the primary function of the IQS450?
A:The IQS450 supplies the high-frequency excitation signal to the proximity transducer and converts the probe signal into a stable analog output for machinery protection and condition monitoring systems.

Description

The Vibro-Meter IQS450 S3960 204-450-000-002-A1-B21-H5-I0 is an eddy-current signal conditioner designed for use with the TQ42x proximity transducer and EA402 extension cable to provide accurate non-contact measurement of shaft vibration, axial position, and displacement in rotating machinery. It supplies the excitation signal for the transducer and converts the measured gap into a stable analog output for machinery monitoring systems. This configuration offers a 2 mm linear measuring range, 8 mV/μm sensitivity, DC to 20 kHz frequency response, and a 5 m system length, making it suitable for continuous condition monitoring of critical equipment such as steam turbines, gas turbines, compressors, pumps, and generators.
