Tuning Fork Level Switches
Description
Explosion-Proof Tuning Fork Level Switches prevent overfill (high) or dry run (low) conditions in liquids, fine-grained solids, granular plastics, gravel, and powders. The intuitive LEDs located inside the housing provide a clear indication of the Tuning Fork's operational state without requiring the unit to be pulled from service. The level switches can be ordered either as HTF1740 with a customer-specified insertion length of 5 to 10 in. for side-mounted applications or the HTF1741 with a customer-specified insertion length of 11 to 118 in. for top-mounted applications.
