Bruel & Kjaer Piezoelectric Accelerometer Type 8305

(Standard Reference Accelerometer — Type 8305)
Traceable to National Institule of Metrology (Thailand):NIMT
The Brüel&Kjær Standard Reference Accelerometer Type 8305 is
designed to be used in laboratories for making accurate calibrations
of vibration transducers.
The 8305 has two 10–32UNF threads, one in its base
and one in its top, so that it may be mounted onto a vibration exciter
table and used for calibrations employing the back-to-back
comparison method. An individual certificate of calibration,
which includes the frequency response curves, is supplied
with each accelerometer.

Bruel & kjaer
Conditioning Amplifier Type 2626

The Bruel & Kjaer 2626 Conditioning Amplifier is designed as a charge amplifier.
It offers wide conditioning possibilities to different transducers and measuring
requirements. The amplifier features a 3 digit sensitivity adjustment network which
enables the amplifier sensitivity to be adjusted to the particular transducer used.
The network is calibrated in pC/g. The amplifier has a rated output stepwise
adjustment between 1 mV/g and 10 V/g depending on the sensitivity of
the transducer. The maximum gain is 60 dB.

Endevco
Charge Amplifier Calibration Model 2947B-2
⦁ Allows simulation of a piezoelectric transducer charge output
⦁ Precision 1000 pF shielded capacitor
⦁ Used for charge amplifier calibration
⦁ Converts voltage to charge
⦁ Easy to use
The Endevco® model 2947B-2 is a stable, precision, 1000 pF shielded capacitor designed specifically for calibrating charge sensing amplifiers. The voltage output from a signal generator is readily converted to a charge signal by connecting a capacitor in series between the generator and charge amplifier.
