High Temperature Float Switches

Are You Looking For a High Temperature Float Switch?

FPI’s high temperature float switches provide consistent reliable switch points in high temperature and other extreme applications. These sensors are made with durable stainless steel floats that slide on a stainless-steel stem. As the float moves over the high temperature rated internal switch, its built in magnetic field activates the reliable switch. High temperature level switches can be mounted on top of the tank, the side of the tank or from the bottom of the tank. High temperature rated Teflon wire or optional Kynar cable protects the lead wires as they exit the high temperature environment. These specially designed sensors can operate in temperatures up to 500F with special considerations.

Benefits of Using a FPI High Temperature Float Switch

FPI high temperature sensors are designed to maximize life cycles when operating in process temperature exceeding 300F. The high temperature design is highly reliable and are designed to a 1/8” tolerance and 1/16” repeatable accuracy. Our flexibility in design and manufacturing allows us manufacture your specific sensor to achieve your operation requirement while maximizing its quality in your application. Our custom sensors have many available options and features including built in optional temperature sensors or temperature switch. This sophisticated high temperature design is still affordable and an excellent option for demanding OEM applications. Custom high temperature float switches can be built in 72 hours to meet your exact specifications.

Typical Applications

Special designed high temperature float switches are needed when the maximum temperature of your application exceeds 300F. With special high temperature design considerations, a sensor can be used in temperatures up to 500F. These high temperature sensors are typically used in hot oil applications, heated cleaning applications, steam applications, lubrication etc. These sensors are used in high temperature applications to provide high level alarm, low level alarm and process level points. In addition, integrated temperature sensors for optional temperature monitoring is available.
