TYPE 4519

Miniature Accelerometer, 10 MV/G, Side Connector

Miniature accelerometer designed for measurements in confined spaces and delicate structures. The transducer has an integral m3 stud, and is hermetically sealed to provide high resistance to harsh environments. 

見積もり依頼

Type 4519 is a piezoelectric Shear accelerometer with integral electronics, together with type 4519-001, 4519-002 and 4519-003, who make up this series of transducers.

The transducers feature an M3 side connector, and are hermetically sealed to provide high resistance to harsh environments. 
The miniature deltatron accelerometer family all have high resolution, giving an excellent signal-to-noise ratio. 

USE SCENARIOS

  • Hermetically sealed
  • Low weight
  • Low-impedance output
  • Measurements in confined spaces
  • Measurements on delicate structures
  • 360° orientation (Types 4519-002 and 4519-003)
  • High frequency range (> 20 kHz)

Two types have been designed for mounting on the object by means of an integrated M3 threaded stud and two types for adhesive mounting with 360° freedom of orientation.

CHARACTERISTICS

The piezoelectric accelerometers feature built-in preamplifiers. The sensitivity is expressed in terms of voltage per unit acceleration (mV/g). In the Shear design, the piezoelectric element undergoes shear deformation as in the DeltaShear design.

Two rectangular slices of piezoelectric material are arranged on each side of a rectangular centre post. This design gives a high degree of linearity, and excellent immunity to base bending and temperature fluctuations.

The signal is collected and amplified in the built-in amplifier.The housing material is titanium.

MOUNTING RECOMMENDATION

Due to the small size, careful mounting is required to ensure correct operation over the full frequency range of the accelerometer.
