CE281 444-281-000-111 Piezoelectric Accelerometer

CE281 444-281-000-111 Piezoelectric Accelerometer 

Functional Description

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.
