Pneumatic Fill Switch (PFS)

Reliable fill detection for pneumatic feed delivery systems

The Pneumatic Fill Switch (PFS) works with the Feed Level Sensor (FLS) to detect feed bin fills in a pneumatic feed delivery system.

The OMNI-Feed software needs to know when a feed bin has been filled. In feed delivery systems where feed is delivered through the bin lid using an auger, the Feed Level Sensor detects the bin lid opening and tells OMNI-Feed a ‘fill event’ has occurred.

In pneumatic feed delivery systems, the feed is blown into the bin without opening the bin lid. Because the lid is not opened while the bin is being filled, the FLS cannot detect the fill event.

The PFS senses the pressure change when the feed tube is pressurized and sends a signal to the FLS to let it know the bin is being filled. All feed bins that are being monitored by a Feed Level Sensor and are using pneumatic feed delivery must have a Pneumatic Fill Switch.

Features Easy installation in most bin configurations Weather-resistant enclosure and materials All mounting hardware included Ratings Electrical: 40 mA Minimum pressure during fills: 0.25 psi Maximum pressure during fills: 10 psi Operating range: –40 to 150°F (–40 to 66°C)
