LS154 Float Level Switch
Float level switch (also named float switch) is consisted of a magnetic float, a stem with magnetic reed switch, the magnetic float moves with liquid level to actuate a hermetically sealed magnetic switch within the stem. The level switches are usually used for vessels having high-level or low-level alarms. Multi-point level switches can be designed according to customers' specifications.
Since technologies have become more and more advanced, the float level switch needs to be more safe, convenient and low cost. These float switches are extremely compact, simple and easy to install on any limited space, and will not be effected by electrical interference. They can withstand chemicals, high temperatures and pressures if the correct material of the float switch is selected.
- Robust, good look, compact design
- Withstand exposure to harsh chemicals
- Unaffected by electrical interference, high temperatures up to 200℃ (custom design is available by special order), high pressures up to 4.0MPa
- Reliability, ruggedness and service
- Switch operation is reversible by inverting float and normally open condition. Rotating switch by 180° to achieve normally closed operation for horizontal mounting level switch
- EPDM compression gasket seals non-threaded holes
- These float level switches are CQC, CE and IS09001-2015 certified
- A variety of float ball dimensions is selectable for the compatibility of various medias, such as oil water interface detecting and diesel oil SG float
- The temperature sensor and level switch compound sensor can be selected
For chemical processing, petrochemical, food and beverage, and marine applications
