Description 

The CE311 piezoelectric accelerometer from Meggitt’s vibro-meter® product line is a vibration sensor designed for the monitoring and protection of machinery in harsh industrial environments and/or hazardous areas.

The CE311 sensor features a symmetrical shearmode measuring element using polycrystalline material. The sensor uses integrated electronics to provide the required signal processing, eliminating the need for an external signal conditioner (charge amplifier). The electronics also performs charge-to-current conversion in order to provide a current-modulated output signal that is suitable for transmission over long distances.

The CE311 is fitted with an integral cable (twisted pair, shielded) in a hermetically sealed link, protected by a flexible, leak-tight protection tube (stainless-steel hose). More specifically, the sensor and protection tube are hermetically welded to one another, resulting in a system that is fully protected against cooling fluids, lubricants, water, steam and other potential contaminants. This makes the CE311 an extremely reliable device suitable for the long-term monitoring of vibration in many industrial applications.

The CE311 sensor and electronics are insulated from their housings (integral case insulation) and have a sensitivity of 50 µA/g.

The CE311 is available in different versions with various cable lengths for different industrial environments: standard versions for use in standard (non-hazardous) areas and Ex versions for installation in hazardous areas.

The CE281 piezoelectric accelerometer from Meggitt’s vibro-meter® product line is a vibration sensor designed for the monitoring and protection of machinery in harsh industrial environments and/or hazardous areas.

The CE281 sensor features a centre-mounted symmetrical shear-mode measuring element using polycrystalline material. The sensor uses integrally attached electronics to provide the required signal processing, eliminating the need for an external signal conditioner (charge amplifier). The attached electronics also performs charge-to-current conversion in order to provide a current-modulated output signal that is suitable for transmission over long distances.

The sensor head is connected to the attached electronics by an integral cable (low-noise, shielded) in a hermetically sealed link, protected by a flexible, leak-tight protection tube (stainlesssteel hose). More specifically, the sensor head, protection tube and electronics housing are hermetically welded to one another, resulting in a system that is fully protected against cooling fluids, lubricants, water, steam and other potential contaminants.

The CE281 sensor and electronics are insulated from their housings (integral case insulation) and have a sensitivity of 10 µA/g. The CE281 is available in different versions for different industrial environments: standard versions for use in standard (non-hazardous) areas and Ex versions for installation in hazardous areas.

The CE281 piezoelectric accelerometer is an extremely reliable device that is suitable for the long-term monitoring of vibration in many industrial applications.
