Product Introduction
The CE281 444-281-000-111 piezoelectric accelerometer is a vibration sensor designed for the monitoring and protection of machinery in harsh industrial environments and/or hazardous areas.
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

Product Details
The CE281 444-281-000-111 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.
