Traveller SGA-0B
The SGA0B Strain Gage Input Signal Conditioning Amplifier is a precise, fully programmable analog channel for strain gages, strain gage based transducers, potentiometers and voltage sources. The SGA0B is a single-channel unit for a EUROCARD 19'' with built-in power supply (24 VDC) and USB interface which allows the user to configure conditioner from any computer using special settings program.
Features
- Constant-voltage software programmable bridge excitation.
- Bridge completion module for quarter or half-bridge 1000/350/120Ω strain gage and transducer circuits.
- Built-in shunt calibration circuit with internal switches for user-software-selectable calibration configurations
- Built-in four-pole software programmable Butterworth low-pass filter
- Precise, software programmable electronic bridge-balance circuit
- Fully programmable features: bridge excitation, gain, low-pass filter, calibration and bridge balance
- All functions of particular analog channel are controlled and serviced by high speed low power CMOS microprocessor unit and stored in non-volatile EEPROM memory
