In harsh industrial environments, vibration sensors face constant threats from moisture, contaminants, and cable failures. The Vibro Meter 444-311-000-033 CE311 piezoelectric accelerometer addresses these challenges with a hermetically sealed, integrated design that eliminates common failure points.
Introduction to the 444-311-000-033
The Vibro Meter 444-311-000-033 is a piezoelectric accelerometer from the vibro-meter® product line. It is designed for vibration monitoring in harsh industrial environments and hazardous areas. The sensor features a symmetrical shear-mode measuring element with polycrystalline material and integrated electronics for charge-to-current conversion. This eliminates the need for external signal conditioners and enables long-distance signal transmission.
Industry Applications
The 444-311-000-033 is ideal for continuous vibration monitoring in machinery such as turbines, compressors, pumps, and fans. Its robust construction makes it suitable for applications in oil and gas, power generation, chemical processing, and other industries where reliability is critical. The sensor is available in Ex versions for use in potentially explosive atmospheres.
Installation & Mounting
Mount the Vibro Meter 444-311-000-033 using four M6 × 35 Allen bolts with spring-steel washers. The recommended mounting torque is 15 Nm (11.1 lb-ft). The integral cable with flying leads simplifies connection to monitoring systems. The hermetically welded sensor and protection tube ensure the assembly is impervious to cooling fluids, lubricants, water, steam, and other contaminants.
Maintenance & Reliability
The hermetically welded stainless steel construction of the 444-311-000-033 minimizes maintenance needs. The sensor is dynamically calibrated at the factory and does not require subsequent recalibration. Regular inspection of the cable and connections is recommended. The design ensures long-term stability and reduces the risk of unexpected downtime.
Selection Guide & Purchasing Advice
When ordering, specify the standard version with 12 m integral cable using part number 444-311-000-033. This accelerometer is a direct replacement for older models and offers enhanced durability.
