Ponte Amplificadora para Sensor
Principais características


• Strain gage sensor amplifier
• 18 Vdc to 32 Vdc supply voltage
• NEMA 4 housing
• Selectable excitation voltages: 3 V or 5 V @ 70 mA
• 4-20 mA analog output
• Increases signal-to-noise ratio in noisy environments
• Effects of voltage drops in excitation sources are eliminated
• Signals may be sent to the data systems from low impedence


The Model U3W amplifier supplies a highly regulated bridge
excitation voltage for the transducer and converts the millivolt
signal of the transducer to a 4 mA to 20 mA three-wire current
output signal. The Universal In-line features two selectable excitation
voltages, programmable gain settings, a wide adjustment
range on the zero, and a buffered solid-state shunt cal relay for
quick calibration.
