Part of the proven 3300 XL series, this probe delivers stable performance under wide temperature swings, high humidity, and mechanical stress. With a polyphenylene sulfide (PPS) tip and stainless steel case, the 330195-02-12-05-CN resists corrosion and wear, making it ideal for critical rotating machinery.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eAll values are directly from the product datasheet for the 330195-02-12-05-CN.

In gas turbines and compressors operating near coastal areas, the probe's humidity resistance (less than 3% ASF drift) ensures reliable data over long monitoring periods. For steam turbines in power plants, the extended temperature range accommodates high ambient heat near the bearings without compromising the pressure seal—a common failure point in lower-rated probes.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup Guidance\u003c\/h2\u003e\u003cp\u003eWhen installing the 330195-02-12-05-CN, ensure the 3\/8-24 UNF thread is engaged no deeper than 0.563 inches to avoid mechanical binding or internal damage. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; however, it is not pressure-tested before shipment. If your application requires a tested pressure seal, contact the custom design department. Avoid exposing the probe to temperatures below -34°C during installation or operation, as this may cause premature failure of the pressure seal.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eTo maximize service life, inspect the Viton O-ring and probe case for signs of wear or corrosion periodically, especially in humid or chemically aggressive atmospheres. The stainless steel case (AISI 303\/304) offers good general corrosion resistance but should be cleaned with mild solvents if contaminated. The probe's humidity-tested design (IEC 68-2-3) minimizes signal drift, reducing the need for frequent recalibration. Replacing the probe at scheduled intervals—rather than after failure—prevents unplanned downtime and costly repairs.\u003c\/p\u003e\u003ch2\u003eTroubleshooting Common Issues\u003c\/h2\u003e\u003cp\u003eIf the 330195-02-12-05-CN exhibits erratic readings, first verify the ambient temperature: exposure below -34°C can damage the pressure seal, leading to moisture ingress and signal instability. Check the DC resistance at the connector; it should measure 7.45 Ohm ± 0.50 Ohm. A significant deviation may indicate a damaged cable or internal short. For applications with high humidity, confirm the Average Scale Factor remains within the 3% threshold; if not, re-evaluate the probe location or consider an extended temperature variant. Contact Bently Nevada support for detailed diagnostics.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Bently Nevada 330195-02-12-05-CN, verify the total length needed (0.5 m standard) and ensure the agency approval option (CN Country Specific) matches your region. For applications exceeding the standard temperature range, consider the extended temperature option available in the 3300 XL series. PLC Source PRO stocks this exact model—part 330195-02-12-05-CN—and can assist with compatibility verification for your control system.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44426789617763,"sku":"330195-02-12-05-CN","price":272.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/330195-02-12-05-00-1_0100f00a-4a3f-44e3-bc08-ad14cd3d3287.jpg?v=1785458768","url":"https:\/\/www.plcsourcepro.com\/he\/products\/bently-nevada-330195-02-12-05-cn-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
