摘要

Monitoring device (1) for industrial ventilation equipment configured for attachment to the fan housing, characterized in that it comprises: - a set of analog input channels (2) for temperature measurement, configured for connection to resistive temperature sensors of the PT100 type located in the fan (100); - a set of digital input channels (3) for temperature measurement, configured for connection to PTC type resistive temperature sensors located in the fan (100) in order to determine if said temperature is above a certain threshold of security; - a tilt sensor (4) configured to determine the pitch and roll tilt angles of the fan; - two pneumatic pressure sensors for measuring the direction of rotation connected to two channels for acquiring pneumatic signals (5) from positions located in the internal duct of the fan (100) respectively in front of and behind the impeller, so that the difference between Both measurements allow determining the direction of air flow through the fan (100); - speed measurement input channels (6) connected to a sensor configured to detect the passage of the fan blades (100) to determine the speed of rotation; - an analog input channel for vibration measurement (7), configured for connection with an accelerometer located in the fan (100); - a set of analog input channels (8) to measure additional signals from sensors located in the fan (100); - a digital output channel (9) configured to connect/disconnect a heating resistance to prevent moisture condensation inside the fan motor (100); - an input channel (10) to monitor if current flows through the heating resistance; - a storage medium configured to store the data obtained by the previous sensors and channels; - an RJ45 connector (12) for communication with an external device via Ethernet; - a power connector (11) for powering the device (1); - at least one processing means (13a, 13b) connected to the previous sensors and channels for managing the operation of the device (1).
