SAT-CAM ™/ SAT-MACT ™ SYSTEM BLOCK DIAGRAM
Emissions Monitoring Interface BoardThe circuit board accepts and processes voltage inputs from four engine exhaust sensors…
- Type J Thermocouple (Iron-Constantan)…Procedures an analog signal proportional to the catalytic converter inlet exhaust gas temperature.
- Same as above for the converter outlet exhaust gas temperature.
- Zirconium Oxygen Sensor…Produces an analog signal proportional, on a log scale, to the percent oxygen content in the exhaust gases at the inlet of the catalytic converter.
- Pressure Transducer…Produces an analog signal proportional to converter pressure differential required for MACT application.
The sensor signals are converted to a serial data stream “message” and transmitted to the satellite via the SatAlarm – Sentry C1D2 ™ modem. The satellite transmits the message to an earth ground station; then to application specific high-speed internet servers and displayed on password protected web sites.
