Description
The Classic 814 Series is manufactured to order. Typically ships from factory within ±14 days ARO.
The Kayden CLASSIC 814 Flow, Level, and Interface Switch features a precision-welded, highly accurate stainless steel sensor.
This switch is ideal for use with liquids, gases, and slurries in both clean and dirty processes.
The CLASSIC 814 Retractable Packing Gland is available with a Raised Face or RTJ flange in a wide range of flange sizes and ANSI ratings for low- and medium-pressure applications.
All Kayden models feature a rugged flameproof enclosure with blind or lens covers available.
