CE311 444-311-000-031 is piezoelectric accelerometer, has a symmetrical shear-mode measuring element using polycrystalline material. Widly used in Heavy duty gas and steam turbines. 

CE311 444-311-000-031 sensor uses integrated electronics to provide the required signal processing, eliminating the need for an external signal conditioner (charge amplifier). The integrated electronics also performs charge-tocurrent conversion in order to provide a currentmodulated output signal that is suitable for transmission over long distances.

CE311 sensor 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). The CE311 is available in standard and Ex versions with various cable lengths, such as 3 m integral cable, 6m integral cable, 12m integral cable.

Q&A：
1. What are the applications of the CE311 piezoelectric accelerometer?
A: The CE311 is used for vibration monitoring in harsh industrial environments and/or hazardous areas, mainly for machinery monitoring and protection.
2. What are the recommended mounting points for CE311 sensors?
The sensors should be mounted on motor end bells as close as possible to bearings; fan and pump pillow blocks are also common acceptable mounting locations.
3. Are CE311 sensors allowed to be installed at structural resonant locations
No. The sensor must avoid structural resonant locations when measuring the motion of the entire machine structure.
