SISCO liquid level float switch features a 304/316L stainless steel housing with radial mounting. It is rated for pressure up to 32MPa and media density 0.5-2 g/cm3. The float switch employs a magnetic coupling mechanism for stable resistance conversion and offers optional PTFE lining for corrosion resistance.
Accurate Level Measurement & Smart Signal Output
- Measures liquid level from 300 mm up to 9000 mm with a repeatable accuracy of ±10 mm.
- Integrated LCD simultaneously displays level percentage and live 4- 20 mA loop current for on-site verification.
- HART protocol is superimposed on the analogue signal, enabling remote calibration and diagnostics.
- Two independently adjustable alarm setpoints allow easy configuration of high/low level limits.
- Output supports 4-20 mA, 0-10 V, 0-5 V, or RS485 Modbus to interface with PLCs and SCADA systems.

Tips: How does a liquid level float switch work?
A liquid level float switch operates by using a magnetic float that rises and falls with the liquid surface inside a container. As the float moves along a guide rod, the magnetic field activates a reed switch or changes the resistance of a built-in sensor element. This resistance variation is linearly converted into a standard 4-20 mA current signal, with HART protocol superimposed for digital communication. The float switch can display the level percentage and loop current on an integrated LCD. Advanced models allow users to set high and low alarm points, and the measured data can be transmitted over distances up to 1000 m for remote monitoring and control.
