Abstract
A system for monitoring the composition of the air environment in livestock buildings has been developed. The system consists of a programmable logic controller, frequency converter, operator panel and gas sensors. A control program in LD language was developed for multi-stage control of the fan motor speed. The linear nature of the relationship between the fan speed and the air flow it creates has been experimentally confirmed.
