TQ902-011 111-902-000-011(A1-B1-C70-D2-E1000-F0-G0-H10) Advantages
TQ902-011 111-902-000-011(A1-B1-C70-D2-E1000-F0-G0-H10) Proximity sensor provides high-reliability non-contact displacement measuring solutions for VM600 series rotating machinery monitoring systems. The built-in multi-layer shielding cable and probe internal isolation structure automatically filter high-frequency electromagnetic interference noise generated by on-site drive motors, frequency converters and high-voltage cabinets, avoiding raw signal distortion and equipment false alarms caused by external clutter signals, greatly improving the overall stable operation performance of the complete monitoring system. Equipped with Swiss imported high-sensitivity induction coil and independent built-in temperature compensation structure, the sensor automatically corrects measuring deviation caused by long-term high-temperature environment changes of bearing pedestals, maintains consistent measuring linearity within full working temperature range, and ensures long-term accurate collection of equipment shaft vibration and displacement data without frequent on-site calibration. Full signal isolation design between probe and transmission cable thoroughly eliminates ground loop interference of field equipment, perfectly solving measuring signal drift problems caused by potential difference between sensor and signal conditioner. The fixed measuring range, cable length and installation size parameters defined by model suffix A1-B1-C70-D2-E1000-F0-G0-H10 realize perfect parameter docking with matched IQS900 signal conditioner, no complex parameter debugging is required during field installation, reducing project construction difficulty and shortening overall commissioning cycle. The compact stainless steel fully sealed probe shell has outstanding oil-proof, dust-proof, high temperature and anti-radiation performance, can operate stably for many years in industrial sites with harsh environmental conditions, slow down aging of internal induction components and extend the whole service life of the proximity sensor. Comprehensive multi-dimensional protection structures including over-temperature, cable stretch, reverse installation and electromagnetic impact are integrated inside the sensor; on-site improper operation or instantaneous electromagnetic surge will only protect the probe measuring channel independently without damaging matched signal conditioner and VM600 rack modules. Standard threaded installation mode saves equipment monitoring support layout space, unified cable interface supports rapid wiring matching, and the sensor can be freely added or replaced during system transformation and capacity expansion without modifying original VM600 system control programs. Every TQ902 proximity sensor is manufactured strictly in accordance with Swiss precision industrial production standards, and passes high-low temperature cycle aging test, full-range measuring linearity calibration, anti-interference stability test and long-duration continuous operation durability test before factory delivery, fully meeting high-reliability online monitoring requirements of critical rotating equipment in power, chemical and metallurgical industries.
