LCA Series Adjustable Flow Monitor

LCA flow switch: compact precision with a wide adjustment range

The LCA flow switch is designed for engineers looking for a compact monitor without sacrificing adjustment options. Thanks to its smart design, the sensor is highly suitable for systems where installation space is limited but accurate fine adjustment of the switch point is required.

Why use the LCA series?

The LCA flow switch combines robust construction with high sensitivity. This makes the monitor widely applicable in various sectors:

• Welding systems: monitoring of cooling water or shielding gas.
• Vacuum systems: detection of minimal gas flows.
• Analysers: reliable flow control for sample streams.
• Cooling systems: protection of critical components in compact machines.

Operation and adjustability

The operating principle of the LCA series is based on a spring-assisted magnetic piston:

• Flow response: as flow increases, the magnetic piston is moved against a bias spring.
• Actuation: as soon as the magnet reaches the position of the adjustable reed switch, the contact is activated.
• Reset: as flow decreases, the spring pushes the piston back. De-actuation (reset) takes place on average at a flow 40% lower than the actuation point.

Installation and advice

The LCA flow switch should preferably be mounted vertically with the inlet port facing down. Although horizontal mounting is possible, it affects the adjustment range of the unit. For long-term, trouble-free operation, we recommend using a 100 micron filter to prevent contamination of the internal parts.
