The first digit indicates system length: 5 = 5.0 meters, 9 = 9.0 meters. The second digit indicates mounting: 0 = panel mount, 1 = DIN-rail mount. The third digit indicates agency approvals: 0 = none, 5 = multiple (CSA, ATEX, IECEx). Therefore, 330850-90-05 decodes as 9.0 m, panel mount, with multiple approvals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What probe and extension cable does the 330850-90-05 require?\u003c\/strong\u003e\u003cbr\u003eA: It accepts one noncontacting 3300 XL 25 mm proximity probe and a matching 3300 XL 25 mm extension cable.

Both share the same 9.0 meter system length and multiple agency approvals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this sensor with a 7200 series monitor?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The 3300 XL 25 mm Proximitor Sensor output is identical to 7200 and 25 mm DE integral systems, enabling direct upgrades without monitor reconfiguration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What happens if the supply voltage is more positive than -23.5 Vdc?\u003c\/strong\u003e\u003cbr\u003eA: Operation at a voltage more positive than -23.5 Vdc can result in reduced linear range. Maintain -17.5 to -26 Vdc without barriers, or -23 to -26 Vdc with barriers.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guide\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eVerify all power to the monitoring system is de-energized before installation\u003c\/li\u003e\n\u003cli\u003eMount the Proximitor Sensor in a panel using the supplied hardware for the 90 (panel mount) option\u003c\/li\u003e\n\u003cli\u003eConnect the 3300 XL 25 mm proximity probe to the sensor input via the extension cable\u003c\/li\u003e\n\u003cli\u003eWire the power supply to the SpringLoc terminals: -17.5 to -26 Vdc, observing polarity\u003c\/li\u003e\n\u003cli\u003eConnect the output signal to the monitor input channel\u003c\/li\u003e\n\u003cli\u003eGap the probe to 7.0 mm (275 mils) using an AISI 4140 steel target for calibration verification\u003c\/li\u003e\n\u003cli\u003eEnergize the system and verify output voltage matches the expected scale factor\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eSelection Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSelect 330850-90-05 for panel-mounted 9.0 meter 25 mm systems requiring multiple agency approvals\u003c\/li\u003e\n\u003cli\u003eFor DIN-rail mounting, choose 330850-91-05 instead\u003c\/li\u003e\n\u003cli\u003eFor 5.0 meter system length, select 330850-50-05 (panel) or 330850-51-05 (DIN)\u003c\/li\u003e\n\u003cli\u003eWithout agency approvals, 330850-90-00 (panel) or 330850-91-00 (DIN) are available\u003c\/li\u003e\n\u003cli\u003eAlways order the matching 3300 XL 25 mm probe and extension cable for complete system assembly\u003c\/li\u003e\n\u003cli\u003eVerify your monitor accepts 25 mm proximity probe input characteristics before ordering\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":54000941007032,"sku":"330850-90-05","price":165.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/330850-90-05r180_575f1956-9f59-40c9-8b8d-ccea28857f3a.png?v=1787898436","url":"https:\/\/www.globalpetroparts.com\/products\/bently-nevada-3300-xl-25mm-330850-90-05-proximitor","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
