CE311 444-311-000-031 Piezoelectric Accelerometer With 12m Integral Cable

CE311 444-311-000-031 Piezoelectric accelerometer
 

Description:
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.
