Installation & Setup Guidance
Mount the 444-311-000-023 accelerometer using four M6 × 35 Allen bolts (DIN 912, ISO 4762) with M6 spring-steel washers (DIN 7980). Apply a mounting torque of 15 Nm. The sensor includes an integral cable with flying leads for connection. Ensure the mounting surface is clean and flat to achieve optimal frequency response.
Maintenance & Reliability
The hermetically welded design of the Vibro Meter 444-311-000-023 provides excellent protection against cooling fluids, lubricants, water, steam, and contaminants. This construction minimizes maintenance needs and ensures long-term reliability. Dynamic calibration is performed at the factory and no subsequent calibration is necessary, reducing total cost of ownership.
Selection Guide & Purchasing Advice
When ordering, specify part number 444-311-000-023 for the standard version with 6 m integral cable. The sensor is available with different cable lengths; verify your application requirements. For reliable supply and technical support, procure this industrial automation module from PLC Source PRO (ubest101). Ensure your monitoring system includes a galvanic separation unit if required.
