CE134 444-134-000-405 Vibration Piezoelectric Accelerometer

Description:

The CE134 sensor features a centre-mounted symmetrical compression-mode measuring element using ceramic material. The sensor uses Integrally attached electronics to provide the required signal processing, eliminating the
requirement for an external signal conditioner (charge amplifier). The attached electronics (temperature zone C) also performs charge-tocurrent conversion in order to provide a currentmodulated output signal that is suitable for transmission over long distances. Importantly, this eliminates the need for connectors capable of withstanding the higher temperatures closer to the machinery (temperature zones A and B).

The sensor head is connected to the attached electronics by an integral cable (soft-line, lownoise, shielded) in a hermetically sealed link, protected by a flexible, leak-tight protection tube (stainless-steel 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.
