Description
The CE281 piezoelectric accelerometer fromMeggitt’s vibro-meter® product line is a vibrationsensor designed for the monitoring andprotection of machinery in harsh industrialenvironments and/or hazardous areas.
The CE281 sensor features a centre-mountedsymmetrical shear-mode measuring elementusing polycrystalline material. The sensor usesintegrally attached electronics to provide therequired signal processing, eliminating the needfor an external signal conditioner (chargeamplifier). The attached electronics also performscharge-to-current conversion in order to providea current-modulated output signal that is suitablefor transmission over long distances.

The model code 444-281-000-111 designates the CE281 with standard configuration and specific cable length/connector variant. The differential output signal minimizes noise pick-up due to electrical ground potentials.
The sensor operates on the piezoelectric principle, generating a charge output proportional to applied acceleration. As a passive device, it requires no input power. The charge output is processed by an external charge amplifier such as the IPC70x series signal conditioner, which converts the charge signal into a current or voltage signal compatible with monitoring and control systems.
The CE281 444-281-000-111 Vibro-Meter Piezoelectric Accelerometer may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Sensitivity is rated at 100 pC/g ± 5%, calibrated at 120 Hz with 5 g excitation at 23°C. The dynamic measurement range spans 0.01 to 400 g peak, with overload capacity up to 500 g peak for short-duration spikes. Linearity is ± 1% from 0.01 to 20 g peak and ± 2% from 20 to 400 g peak. Transverse sensitivity does not exceed 3%. The resonant frequency is above 22 kHz nominal.
Frequency response is flat within ± 5% from 0.5 to 6000 Hz, with a typical + 10% deviation at 8 kHz. The lower cutoff frequency is determined by the external signal conditioner configuration.

Current Output Signal: The CE281 utilizes a modulated constant current output (10 μA/g). Because the electronics are built directly into the sensor, it does not require a separate charge amplifier.
Long Distance Transmission: This current output allows for trouble-free signal transmission over long field runs—up to 1,000 meters to your monitoring system.
Technical notes
The sensor head is connected to the attachedelectronics by an integral cable (low-noise,shielded) in a hermetically sealed link, protectedby a flexible, leak-tight protection tube (stainlesssteel hose). More specifically, the sensor head,protection tube and electronics housing arehermetically welded to one another, resulting in asystem that is fully protected against coolingfluids, lubricants, water, steam and other potentialcontaminants.
