liquid level float switches
The AMETEK Float Switch family is made up of model series F8300, 610XXX and 8TJ143XXX. These devices open or close an electrical circuit at a predetermined level of liquid. They have been developed primarily for use in aircraft fuel and lubrication tanks but are equally suited for many industrial applications in remote and non-accessible locations where liquid level control is important.
Switches are designed for use with liquids under MIL-F-5572, MIL-F-5616, MIL-F5624, MIL-L-7808, and MIL-L-23699 throughout a temperature range of -65º to 275ºF, but may be used with most other liquids.
