Piezo element sensor8/24/2023 Low frequency model is used in the petrochemical, machine tool, and paper industries for monitoring of slow speed agitators, cooling towers. Model 108 sensors are not recommended for permanent monitoring because they have external faraday shield subject to loss of isolation.įor such applications, Models 101, 103, 104, 105, 107 with internal faraday shield are prefered. Medium frequency version monitor overall vibration on pumps, motors, fans. The piezoelectric sensor, which consists of only a detecting part, is often called a piezoelectric type. High frequency version monitor the vibration on roller bearing, pumps cavitation. Piezo elements come in handy when you need to detect vibration or a knock. Typical applications: Ideal for walk-around vibrations measurement in the rugged environments of industrial machinery monitoring. The active element of Brüel & Kjær vibration sensors consists of piezoelectric discs or slices loaded by seismic masses and held in position by a clamping arrangement. This filter attenuates the sensor mechanical resonance and the associated distortion and overload. Low frequency accelerometers (A=9) incorporate a low-pass filter within the conditioning electronic. Large choice of frequency range will help to fit almost every customer requirements. Low noise electronic and a temperature compensated design will give you accurate result over the complete temperature range. Annular shear mode design will prevent from thermal transient and from spurious signal from high transverse vibrations. TE Connectivity piezoelectric sensors provide durable vibration, accelerometer, or dynamic switch elements for a wide range of markets and applications. Signal ground is isolated from the mounting surface to prevent ground loops. It uses the industry standard ®ICP 2-wire voltage transmission technique with a 4 mA standard constant current supply. The epoxy sealed piezoelectric accelerometer model 108 is design to monitor the vibration in harsh industrial environment. General Characteristics (metric): Hex 0.7 inch, Height = 1.6 inch, weight=3.0 Oz, 120☌.
