TRAFAG`S OWN ASIC
(ASIC = Application Specified Integrated Circuit)
Highest degree of reliability and functionality are the hallmark of Trafag products.
Special demands are placed particularly on signal processing by pressure transmitters: in order to realize disturbance-free signal amplification at a simultaneously high signal-to-noise ratio, a special amplifier electronic system in the form of an ASIC was developed.
Advantages in comparison with conventional electronics:
- Supports all prevalent sensor technologies (thin film, thick film, piezo-resistive)
- Temperature range -40...125°C
- Three independent input channels (pressure, temperature and one further digital auxiliary parameter)
- Signals of only just a few mV can be processed without problem (i.e. free of drift)
- Comprehensive compensation possibilities via three-dimensional sets of characteristic curves
- Long-term drift < 0.1% FS
- Noise < 0.1 % FS (Vpp)
- The rectified output signals are available as pulse-width or pulse-density signals
