LSMT Magnetic Top Mounted Level Switch
Proven top-mounted magnetic reed switch for single or multiple level sensing — works in conductive and non-conductive liquids.
LSMT magnetic top mounted level switch is an established and reliable technique in industry for single or multiple liquid level sensing and control in open or pressurized vessels. It provides trouble-free service in conductive and non-conductive liquids under widely varying temperatures, pressures, liquid viscosity and corrosive conditions. Up to 5 set points in a single probe up to 5,000 mm length.

How the LSMT magnetic top-mounted reed switch is applied for single or multi-level sensing.
Multiple Level Sensing
One top-mounted stem can carry several reed points for multi-level control and alarms.
Conductive & Non-Conductive Liquids
Magnetic reed sensing works regardless of the liquid's conductivity.
Top-Access Tanks
Single top connection where the tank side is inaccessible.
Pump Control & Alarms
Reed contacts trigger pump start/stop and overfill/dry-run alarms.
Pressurised Vessels
Flanged or threaded, up to 10 kg/cm² and 100°C.
Chemical & Process Tanks
SS or PP wetted parts to suit the media.
Choosing the right build: Top-mounted reed stem; single or multiple points; flanged or threaded; SS or PP wetted parts; liquid SG ≥ 0.7; up to 100°C and 10 kg/cm².
