Level Switch LS25:

Section 1: general information

1. General Description

1-1 Features:

Rugged construction.

Safe for flammable, corrosive and toxic liquids.

Suitable for maximum specified pressure 100bar

Special types for high and low temperature

operation (-10 ~220°C), Special (-45 ~400°C)

Available with integral limit switches & reed switches.

Installed for out of ground or under ground vessel. 

Ability to install from side-side and top of the vessel.

Low cost.

Usable for interface process (double liquid).

The Sch LS25 liquid level switch system is designed for use in applications where a simple gauge glass cannot be used. Due to its design the LS25 can safety be used with flammable corrosive or toxic liquids or where operating condition exceed safety limits of glass. The rugged construction of the LS25 make them ideally suited for use in operating environments where extreme temperature and/or pressure may encountered.

The basic LS25 systems consist of a float, float chamber and connection flanges or nipple.

The float chamber is connected directly to the process vessel. The float contains a magnet assembly and is designed and weighed to float in the process liquid.
