in-line charge amplifiers - IEPE powered

QV/02  (Line driver)*

Hybrid Two Wire IEPE Source

QV/04  (Line Driver)*

Hybrid Two Wire IEPE Source

Weight:  20.5g

Dimensions:  Ø15 x 47.5

IEPE:  Miniature 2 Wire Charge/Voltage Converter

Connector:  input 10-32 UNF Microdot  output BNC

Gain options:  0.1, 1 and 10 mV/pC

Note: get the best of both worlds (charge amplification AND IEPE), for use with one channel piezo charge accelerometer such as AT/20 or AT/04 (has male BNC for direct connection)

Weight:  15g

Dimensions:  Ø12.5 x 28.5

IEPE:  Miniature 2 Wire Charge/Voltage Converter

Connector:  input 10-32 UNF Microdot  output 10-32 UNF Microdot

Gain options:  0.1, 1 and 10 mV/pC

Note: get the best of both worlds (charge amplification AND IEPE), for use with one channel piezo charge accelerometer such as AT/20 or AT/04 (has microdot in-line connection)

* in-line converters providing charge/voltage conversion when supplied with a standard IEPE supply current in the range of 4 to 20mA.  The low impedance line drive maintains signal integrity even over distances of several hundred metres, requiring minimal configuration to interface with vibration analysers/data acquisition systems.
