TQ402 Vibration 111-402-000-013 Proximity Transducer

Description:

 The system is based around a TQ402 or TQ412 non-contact sensor and an IQS900 signal conditioner. Together, these form a calibrated proximity measurement system in which each component is interchangeable. The system outputs a voltage or a current proportional to the distance between the transducer tip and the target, such as a machine shaft.
 The active part of the transducer is a coil of wire that is moulded inside the tip of the device, made of Torlon ® (polyamide-imide). The transducer body is made of stainless steel. The target material must, in all cases, be metallic.
 The transducer body is available with metric or imperial thread. The TQ412 version is intended for reverse-mount applications. Both the TQ402 and TQ412 have an integral coaxial cable, terminated with a self-locking miniature coaxial connector. Various cable lengths (integral and extension) can be ordered. 
 The IQS900 signal conditioner contains a high frequency modulator / demodulator that supplies a driving signal to the transducer. This generates the necessary electromagnetic field used to measure the gap. The conditioner circuitry is made of high-quality components and is mounted in a painted aluminium housing.
 Note: The IQS900 signal conditioner matches or betters the outstanding measurement performance and specifications of the IQS450 signal conditioner, which it replaces. Accordingly, the IQS900 is compatible with all TQ9xx and TQ4xx proximity sensors / measurement chains.
 In addition, the IQS900 signal conditioner includes improvements such as: SIL 2 “by design”, improved frame-voltage immunity, improved electromagnetic immunity and emissions, smaller output impedance (voltage output), optional diagnostic circuitry (that is, built-in self-test (BIST)), raw output pin, test input pin, new DIN-rail mounting adaptor and removable screw-terminal connectors for easier installation. The TQ402 and TQ 412 transducers can be matched with a single EA402 extension cable to effectively lengthen the front-end. Optional housings, junction boxes and interconnection protectors are available for the mechanical and environmental protection of the connection between the integral and extension cables.
 TQ4xx-based proximity measurement systems can be powered by associated machinery monitoring  systems such as VM600 cards or VibroSmart ® modules, or by another power supply.
