CO2 control panel board is designed for measuring CO2 concentration in the air of button mushroom (champignon, agaricus) growing room or in the phase III tunel or room.
CO2 control panel board consists of a sealed plastic enclosure, AG-UN-05p CO2 transmitter, pneumatic pump, power supply unit, key switch lock, air tube and electrical assembly. Besides, it is supplied complete with air filter, filter mounting bracket, air tube and a stailess steel condensing pipe.
The panel board is mounted in the clean corridor of the mushroom farm. The air with CO2 is pumped out of the growing room and supplied through the air tube and air filter to CO2 transmitter. CO2 transmitter measures the level of CO2 concentration up to 5000 ppm (30000 ppm - for phase III). The detected value is transformed into an analogue 4-20 mA output signal and transmitted to a mushroom controller.
The issue with moisture condensation in the tube is carried out by a stainless steel condensing pipe and air filter with water trap mounted in the corridor. As well, CO2 transmitter is additionally heated to avoid condensate.
