SET OF TWO - PHYSICAL ACOUSTICS CORPORATION 2/4/6 VOLTAGE PR EN FRANCE

Set of Two Voltage Preamplifiers 2/4/6 I am selling a set of this two units by Physical Acoustics Corporation 2/4/6 voltage preamplifiers, a great solution for a variety of sensors, switch selectable gain, single-ended or differential sensors. New Stored as new, B stock, in very good condition. Description: The 2/4/6 preamplifier has been designed for use with all AE systems available powered via the BNC output signal. It comes with a gain of 20/40/60 dB (switch selectable) and works with a single terminated or differential sensor. Plug-in filters provide the user with flexibility to optimize sensor selectivity and noise rejection. These filters are provided in the low pass (LP), high pass (HP) and band pass (BP) configurations, and offers consistent insertion loss for easy filter exchange without the need for recalibration. Automatic sensor test (AST) is standard. This option provides the sensor with ability to characterize one's own condition and to send a simulated acoustic emission wave that other sensors can Features: -Selectable gain 20/40/60 -Wide dynamic range b'>' 90 dB standard -Low noise b' - Large output signal 20 Vpp in 50? -Single BNC power supply/signal or optional separate power supply/power supply BNC signal - Plug-in filters (uses the same filter as the SPARTAN 2000) - High input impedance - Standard automatic sensor test ï Input protection Electrical specifications: -Selectable gain: 20/40/60 dB + 0.5% dB -Input impedance: 10KO // 15pF -Power requirement: 18-28V DC -Operating current: 30 mA (with AST installed) -28 mA (without AST installed) - Dynamic range: 80 dB (using R15 sensor) 90dB (50O input Environmental specifications: - Temperature: -40 C to +65 C En savoir plus
