🌡️ Temperature switch or temperature sensor? Which one do you need?

A temperature sensor monitors and measures temperature, sending a signal to a control system.

A temperature switch responds when a set temperature point is reached, helping to switch equipment on or off for safe, efficient operation.

They’re used across heating systems, pumps, burners, HVAC, foodstuffs, pharmaceuticals, automotive engineering and industrial equipment.

At Applications Engineering, we supply a wide range of temperature switches, sensors, thermostats, transmitters and controllers.

💧 What actually is a flow switch?

A flow switch is designed to monitor the movement of liquids or gases through a system.

When flow starts, stops or changes, the switch can trigger an action, such as starting or stopping a pump, closing a valve, or activating an alarm.

They’re commonly used across HVAC, water treatment, industrial manufacturing, chemical processing and fire sprinkler systems to help keep operations running safely and efficiently.

We supply a wide range of flow switches, including plastic body, metal body, paddle, magnetic, electronic, adjustable and inline options.

Not sure which flow switch is right for your application? Our experienced team can help you choose the most suitable product.

✅ Small component. Big role in system protection.

Check valves are designed to allow flow in one direction only, helping to prevent reverse flow, pressure build-up and potential damage across plumbing, industrial, heating, cooling, fire protection, oil and gas systems.

From swing check valves to spring, ball, lift and double check valves, the right choice depends on your application, pressure requirements, media type, installation orientation and connection size.

At Applications Engineering, we supply high-quality check valves and strainers, alongside a wide range of valves, switches and sensors for demanding commercial and industrial applications.

With 40+ years’ experience, ISO 9001 certification and knowledgeable support from our team, we can help you find the right product for your system.

When demand increases, not all systems can cope equally. 💧

In water supply systems, maintaining pressure where it matters most is critical, especially in fire protection setups.

A priority demand valve helps ensure that, in high-demand situations, water flow is directed where it’s needed most 💡

It’s a simple but essential component for maintaining safety and system performance.
