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.
