As a core component of the 3300 series 5mm proximity transducer system, this probe excels in restricted-space applications where standard 8mm probes cannot fit. It delivers a high-fidelity voltage output directly proportional to the distance between the probe tip and the target shaft. This real-time data flow is indispensable for Turbine Supervisory Instrumentation (TSI), enabling early fault detection in high-speed compressors, pumps, and small turbines. Its superior stability and linearized response ensure that critical emergency shutdown systems (ESD) operate with absolute confidence, protecting your most valuable industrial assets from catastrophic failure.\u003c\/p\u003e\n\u003ch2\u003eTransducer Configuration Decoding\u003c\/h2\u003e\n\u003ch3\u003e21504 - 3300 5mm Proximity Probe\u003c\/h3\u003e\n\u003cp\u003eThis base model identifies the 5mm tip diameter transducer, optimized for targets with smaller surface areas or where mounting space is at a premium.\u003c\/p\u003e\n\u003ch3\u003e-16 - Unthreaded Length Option\u003c\/h3\u003e\n\u003cp\u003eThe \"-16\" suffix indicates an unthreaded length of 1.6 inches.

This ensures the probe operates within its optimized linear region. The integral cable must be secured with a minimum bend radius of 25.4 mm (1.0 inch) to prevent internal coaxial damage. For hazardous area deployments, ensure all electrical connections are routed through approved safety barriers or galvanic isolators. Proper grounding of the cable shield at the Proximitor side is essential to eliminate high-frequency noise from the measurement signal.\u003c\/p\u003e\n\u003ch2\u003eAdvanced Environmental Resilience\u003c\/h2\u003e\n\u003cp\u003eThe 21504-16-32-10-62 features a Polyphenylene Sulfide (PPS) tip, which provides exceptional resistance to chemical corrosion and high-pressure steam. Its hermetically sealed design prevents oil and process fluids from wicking into the coaxial cable, a common failure point in inferior sensors. This probe integrates seamlessly with Bently Nevada 3500 racks and Honeywell Experion PKS, delivering ultra-low noise signals even in the presence of intense electromagnetic interference (EMI) found in power generation and petrochemical facilities.\u003c\/p\u003e\n\u003ch2\u003eOrdering info\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) Brand New Bently Nevada 21504-16-32-10-62 5mm Proximity Probe.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eFactory-sealed anti-static protective bag.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIndividual calibration and test data certificate.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIntegral 1.0m cable with miniature coaxial connector.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) set of adjustment\/locking nuts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDispatch and Logistics Data\u003c\/h2\u003e\n\u003cp\u003eDelivery time: 2-7 days when payment finish via DHL\/FEDEX\/UPS.

A 5mm probe must be paired with a 5mm Proximitor to maintain the correct scale factor (7.87 V\/mm) and linear range.\u003c\/p\u003e\n\u003cp\u003eQ2: What is the benefit of the \"-16\" unthreaded length?\u003c\/p\u003e\n\u003cp\u003eA2: This allows the probe to penetrate deep into a machine's mounting bore without threading the entire distance, making the initial installation much faster and reducing the risk of cross-threading.\u003c\/p\u003e\n\u003cp\u003eQ3: Is the 21504 probe compatible with 3300 XL extension cables?\u003c\/p\u003e\n\u003cp\u003eA3: Yes, this probe utilizes standard miniature coaxial connectors compatible with both 3300 and 3300 XL extension cables, provided the total system length remains calibrated (e.g., 5.0m or 9.0m).\u003c\/p\u003e\n\u003cp\u003eQ4: How do I handle a \"Not OK\" status on the 3500 monitor?\u003c\/p\u003e\n\u003cp\u003eA4: Check the gap voltage first. If the voltage is outside the -2V to -18V range, the probe is either touching the shaft or is too far away. Readjust the physical gap to restore the -10V signal.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518907211949,"sku":"21504-16-32-10-62","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-21504-16-32-10-62-proximity-probes-yavk1ohk425.jpg?v=1766981299","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-21504-16-32-10-62-3300-5mm-proximity-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
