MODELS 2123, 2124, 2125 CHARGE AMPLIFIERS & MODEL 4121 POWER SUPPLY
BOUCHE LABS MODELS 2123, 2124, 2125 CHARGE AMPLIFIERS & MODEL 4121 POWER SUPPLY
The Model 2123, 2124, and 2125 Charge Amplifiers and 4121 Power Supply are low-priced. The small overall dimensions, dc-power supply or battery operation, are appropriate for use in the test laboratory or in the field.
The Models 2123, 2124 & 2125 Charge Amplifiers are supplied with +15 Vdc and -15 Vdc from the Bouche Labs Model 4121 ac-operated power supply. The Model 4121 power supply is capable of powering up to twenty Model 2120 series Bouche Labs charge amplifiers.
General Description
BOUCHE LABS Model 2123 Solid State Dual Fixed Gain Charge Amplifier has outputs of 10 and 100 mV/pC, is used with piezoelectric transducers such as accelerometers and force gages for general vibration work.
BOUCHE LABS Model 2124 Solid State Dual Fixed Gain Charge Amplifier has outputs of 0.1 and 1.0 mV/pC, is used with high-output piezoelectric transducers or for shock tests with general-purpose accelerometers.
BOUCHE LABS Model 2125 Solid State Dual Fixed Gain Charge Amplifier has its amplifier gain adjusted to the sensitivity of the piezoelectric transducer. The system sensitivities are customer-selected. For example, commonly selected outputs are 10 and 100 mV/g for general vibration work and outputs of 0.1 and 1.0 mV/g are used for accelerometers used in shock tests.
