Level - Series LC40 | Tecfluid

Level Switch Tecfluid LC40

The Tecfluid LC40 is a point level switch for liquids, equipped with a modular float for side or top mounting. When the liquid reaches the setpoint, float movement actuates a magnetic mechanism that triggers a microswitch, reed, inductive, or pneumatic contact, depending on the selected version.

Variants

• LC40: Side mounting.
• LC40-BA: Side mounting where the switching level does not coincide with the nozzle height.
• LC40-V: Top mounting from tank roof.
• LC40-VR: Top mounting for extended insertion depths.

FAQ

Is this a continuous level measurement device?
No. It is a point level switch for discrete level detection.

When is AISI 316L preferred over plastics?
For higher pressure, higher temperature, or when metallic construction is required by process conditions.

Can it be installed externally to the tank?
Yes, with an optional external chamber for side mounting.
