Description
U2W Series Honeywell Amplifier
DESCRIPTION
The Model U2W 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 two-wire current
output signal.
FEATURES
• Strain gage sensor amplifier
• 8 Vdc to 32 Vdc supply voltage
• NEMA 4 or IP66 housing
• Constant voltage mode: 5 Vdc @ 2 mA max. (3K to 10K
Ohm)
• Constant current mode: 0.5 mA with 3 V compliance (2K to
6K Ohm)
• Lightning protection
• 4-20 mA two-wire 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 sources
