Silo pressure sensors continuously monitor positive pressure or vacuum levels inside the silo and trigger alarms or automatic shutdowns at hazardous levels. They are vital for safe filling, especially in cement silos.
Key Features:
Measures internal air pressure within the silo
Triggers alarm or stops filling if pressure exceeds set limits
Can detect vacuum conditions
Integrates with PLC and automation systems
Pressure Switch (Mechanical): Opens/closes at set value
Pressure Transmitter (Analog): Sends continuous pressure signal (4–20 mA)
Differential Pressure Sensor: Used for filter clog detection
