MINEBEA CSA-561, STRAIN AMPLIFIER, ±50000 ΜSTRAIN, DC-10KHZ, 20-2000 GAIN, ±10V OUT

THE MINEBEA CSA-561 IS A DC DYNAMIC STRAIN AMPLIFIER DESIGNED FOR PRECISE MEASUREMENT OF STRAIN, PRESSURE, TORQUE, LOAD, AND DISPLACEMENT USING STRAIN GAUGES OR STRAIN GAUGE TRANSDUCERS. IT ACCOMMODATES 1-GAUGE, 2-GAUGE, AND 4-GAUGE FULL BRIDGE CONFIGURATIONS WITH 350 Ω OR 120 Ω APPLICABLE TRANSDUCERS. THE UNIT FEATURES SELECTABLE BRIDGE EXCITATION OF 2 VDC OR 5 VDC, AN INPUT RANGE OF ±50,000 X 10^-6 STRAIN, AND AN INPUT IMPEDANCE GREATER THAN 1 MΩ. IT OFFERS A BALANCE RANGE OF ±10,000 X 10^-6 STRAIN. OUTPUT SPECIFICATIONS INCLUDE A MAXIMUM VOLTAGE OF ±10 V WITH AN OUTPUT CURRENT OF APPROXIMATELY 5 MA INTO A 2 KΩ LOAD. THE AMPLIFIER PROVIDES A FREQUENCY RESPONSE FROM DC TO 10 KHZ (-3 DB) AND AN ADJUSTABLE GAIN FROM 20 TO 2000, WITH AN ACCURACY OF ±0.5% F.S. NOISE PERFORMANCE IS RATED AT 5 ΜVRMS (INPUT CONVERSION, GAIN 1000, 10 KHZ BANDWIDTH), AND NON-LINEARITY IS ±0.1% F.S. POWER REQUIREMENTS ARE SELECTABLE FROM 100 TO 240 VAC AT 50/60 HZ, CONSUMING APPROXIMATELY 15 VA. THE OPERATING TEMPERATURE RANGE IS 0 TO 40 °C. THE AMPLIFIER WEIGHS 4.10 LBS.
