Model TK1
Side-Mounted
Float Level Switch
DESCRIPTION
The TK1 liquid level switches are float-actuated devices
designed for horizontal mounting in a tank or process
vessel through threaded or flanged connections. This
low-cost switch is ideal for OEM applications where a
single point high or low level alarm is desired.
TECHNOLOGY
The TK1 achieves switching action through the use of a
magnet attached to the float assembly and the magnet’s
interaction with a reed switch.
As the liquid level changes, the float and, therefore, the
float magnet, moves. The proximity of the float magnet
to the reed switch causes the switch to change state,
making or breaking an electrical circuit.
