OPSIS - Sensor Interfaces System

When monitoring the air quality, it is often also of interest to collect meteorological parameters such as temperature, air pressure, wind speed, and wind direction. Signals from such sensors are easily integrated into OPSIS monitoring systems, both in analysers and in stand-alone data loggers. In simple cases, the sensors have analogue outputs for the measured value and perhaps a contact output to signal status. The signals are then connected to the measurement system via the OPSIS modular IOMan interface. IOMan can handle voltage and current signals (active and passive), closing and opening switches, and pulse counters, among others. More advanced sensors can have communication protocols to deliver information and OPSIS data loggers support about twenty different protocols. OPSIS can supply several types of sensors, but it is also possible to connect sensors from other suppliers.
