Engineered specifically for the rigorous demands of cooling tower fans and air-cooled heat exchangers, this piezo-velocity sensor converts vibration velocity directly into a 4-20 mA signal. This allows for seamless integration into DCS, PLC, or SCADA systems without the need for additional signal conditioners. Its rugged stainless steel construction ensures long-term stability and resistance to corrosive cooling tower atmospheres, providing operators with the critical data needed to prevent catastrophic mechanical failures and optimize maintenance schedules.\u003c\/p\u003e\n\u003ch2\u003eDecoding the 190501-18-00-00 Configuration\u003c\/h2\u003e\n\u003ch3\u003e190501 - Product Series\u003c\/h3\u003e\n\u003cp\u003eDefines the Velomitor CT Velocity Transducer, a specialized piezo-electric sensor optimized for lower frequency ranges typical of large fan assemblies.\u003c\/p\u003e\n\u003ch3\u003e18 - Mounting Hardware Option\u003c\/h3\u003e\n\u003cp\u003eSpecifies a 5\/8-18 UNF (Unified Fine Thread) mounting stud.

Ensure the mounting surface is flat to within 0.001 inches and finished to 32 micro-inches. Apply a light film of silicone grease or oil to the mounting surface before torquing the 190501-18-00-00 to 13.5 N-m (10 ft-lb). For electrical integrity, always use shielded, twisted-pair cable to prevent EMI interference from large fan motors. The shield must be grounded at the monitor\/DCS end only to avoid ground loops that can induce false vibration readings.\u003c\/p\u003e\n\u003ch2\u003eSuperior Engineering Edge\u003c\/h2\u003e\n\u003cp\u003eThe 190501-18-00-00 excels where standard accelerometers fail. By utilizing internal integration circuitry, it provides a velocity output that is far more sensitive to the structural resonances and imbalance forces found in large, slow-moving cooling tower fans. It integrates flawlessly with the Bently Nevada 3500\/42M or 1900\/65A monitors, yet its 4-20 mA scalability makes it a \"plug-and-play\" asset for Honeywell Experion PKS or Siemens PCS7 systems. Its hermetically sealed stainless steel case provides an impenetrable barrier against the 100% humidity and chemical treatment vapors common in industrial heat rejection loops.\u003c\/p\u003e\n\u003ch2\u003eLogistics and Handling\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eLead Time:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3-5 days when payment finish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping Carriers:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eWorldwide shipping BY DHL\/FEDEX\/UPS.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePackaging Protocol:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAll units ship in original factory-sealed, anti-static industrial packaging to prevent ESD damage and ensure out-of-the-box calibration integrity.\u003c\/p\u003e\n\u003ch2\u003eTechnical Field Support\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Can I use the 190501-18-00-00 in an ATEX Zone 1 environment?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA1: No, the -00 agency approval suffix denotes the standard version.
