Pressure sensor (definition)

Pressure meter is a device designed to measure pressure in heating systems for the purpose of monitoring and regulating the operation of equipment. The main function of a pressure sensor is to monitor the pressure level of the coolant (usually water or antifreeze) at various points in the heating system.

Installation locations and application:

1. On the boiler — pressure sensors are often installed at the inlet and outlet of the coolant from the boiler. They monitor and regulate pressure, ensuring stable operation of the boiler and preventing possible accidents due to pressure changes.
2. On pipelines — to control pressure in various parts of the heating system. This allows you to quickly identify leaks or other problems with coolant circulation.
3. In the expansion tank - to control the pressure in the system, ensuring the correct functioning of the expansion tank and avoiding its overflow or backflow.

Types of pressure sensors:

1. Membrane sensors - use a membrane that deforms under pressure, changing the electrical signal.
2. Piezoresistive sensors - measure pressure based on changes in the resistance of a semiconductor material under pressure.
3. Capsule sensors — are based on the deformation of the capsule under pressure, which leads to a change in the electrical signal.

Principle of operation:

The pressure sensor transmits a signal to the control system or heating controller, which uses the received data to automatically regulate operation boiler and heating systems. For example, when the pressure decreases, the sensor can initiate the activation of the circulation pump or the supply of additional coolant to maintain the required pressure and temperature.

Application in heating systems:

• Ensuring safety and effectiveness — Pressure control helps prevent overheating or backflow of coolant, which can lead to equipment damage.
• Diagnostics and maintenance — the ability to monitor and analyze the operating parameters of the heating system for a quick response to potential problems.

Pressure sensors play an important role in ensuring the reliability and efficiency of heating systems by monitoring and regulating pressure parameters at various points in the installation.
