Vibro-meter TQ412 S3960 111-412-000-013 Proximity non-contact Transducer

Product Specifications

The TQ402/TQ412, EA402 and IQS900 form aproximity measurement system, from Meggitt’svibro-meter® product line. This proximitymeasurement system allows contactlessmeasurement of the relative displacement ofmoving machine elements.TQ4xx-based proximity measurement systems areparticularly suitable for measuring the relativevibration and axial position of rotating machineshafts, such as those found in steam, gas andhydraulic turbines, as well as in alternators, turbocompressors and pumps.
The system is based around a TQ402 or TQ412non-contact sensor and an IQS900 signalconditioner. Together, these form a calibratedproximity measurement system in which eachcomponent is interchangeable. The systemoutputs a voltage or a current proportional to thedistance between the transducer tip and thetarget, such as a machine shaft.The active part of the transducer is a coil of wirethat is moulded inside the tip of the device, madeof Torlon® (polyamide-imide). The transducerbody is made of stainless steel. The target materialmust, in all cases, be metallic.

Frequently asked questions：

Q1: What is the Vibro-Meter TQ412 S3960 111-412-000-013 Proximity Transducer?
A: The Vibro-Meter TQ412 S3960 111-412-000-013 is a non-contact proximity measurement system used for shaft vibration, shaft position, eccentricity, and displacement monitoring in rotating machinery. It is commonly installed on turbines, compressors, generators, pumps, and other critical industrial equipment.

Q2: What is the TQ412 frequency response range?
A: The TQ412 offers a frequency response from DC to 20 kHz (-3 dB), allowing accurate measurement of both static shaft position and dynamic vibration signals.

Q3: What is the TQ412 operating temperature range?
A: The TQ412 transducer operates within a temperature range of -40°C to +180°C, making it suitable for harsh industrial environments and elevated-temperature machinery applications.

Q4: Can the TQ412 be used for continuous machine monitoring?
A: Yes. The TQ412 is suitable for continuous online monitoring and is commonly integrated into machinery protection and condition monitoring systems.
