Measurement amplifier
HAEHNE
- Signal output -10 to +10 V/V, 4 to 20 mA
- Amplification adjustment range 400 to 3200 V/V
- Integrated display of actual force and parameters
The amplifier DMA is designed for full bridge load cells as well as special web tension sensors. In a cabinet it can be DIN rail mounted or directly to a mounting plate.
This space saving SMD components design combines the advantages of analog and digital electronics:
- Analog: Fast signal processing without AD converter steps.
- Digital: The microprocessor automatically controls zero adjust and calculates the calibration value.
The DMA offers especially OEM´s substantial simplification of commissioning and service:
- Pre-setting of amplification (to be selected in the MENU)
- Plug-in terminal blocks designed for pre-wiring
- Zero adjust and calibration by push buttons
- Display of actual force (as percent of nominal force or actual value)
