  • Signal processing with instrumentation amplifier
  • Anti-aliasing filter, 4-pole, 4 kHz cut-off frequency
  • Sampling ADC with 16-bit resolution
  • 5 V sensor supply regulator
  • 0 V / 5 V shunt stimulation
  • Single chip micro controller
  • EEPROM with 8 kByte
The functionality of the DiMod signal processing is deliberately kept simple. The AD converter used has a 16-bit signal resolution with a noise ratio of max. 1.5 LSB. The gain factor is permanently set via a resistor at the instrumentation amplifier. The DiMods are produced with gain factors adapted to the application measuring range. By setting the appropriate gain, a DiMod is configured for dedicated applications. The sensors are calibrated together with the DiMod as a measuring chain. For a quick check of the measuring chain, a shunt stimulation is present. DiMods are available in a solid as well as a flexible circuit board. Both versions exist as uniaxial versions for a single sensor (Type DTI307.1) and triaxial versions for a sensor with up to three axes (Type DTI307.3). The latter provides all parts for signal processing and digitization in three parallel layouts. Microcontroller, EEPROM, RS-485 bus connection, and sensor supply regulator are installed only once. Apart from that, the functionality remains the same. Since the triaxial DiMod behaves like three parallel-connected uniaxial DiMods to the bus lines, the 8 kB memory of the EEPROMs is divided into three equal parts. Therefore, for compatibility reasons, the uniaxial DiMod only uses this memory range.
