What is Pressure Sensor ?

Introduction to Pressure Sensors

What is it?

Pressure sensors are devices that measure and monitor pressure levels in a variety of applications. They can be used to control and regulate systems, ensure safety, and optimize performance.

Why we use it?

We use pressure sensors to improve system performance, safety, and efficiency by monitoring pressure levels and initiating automatic adjustments as needed.

How it works?

The sensor typically contains a sensing element, such as a strain gauge or piezoelectric crystal, which interacts with a fluid or gas to produce a signal proportional to the pressure. The device then calculates the pressure based on the magnitude of the signal produced.

Major brands that manufacture it

Some of the major brands that manufacture pressure sensors include Honeywell, Siemens, Schneider Electric, and Johnson Controls.


There are different types of pressure sensors, including absolute, gauge, differential, and vacuum models for measuring pressures in various applications. Some models may also feature additional functions, such as temperature sensing or wireless connectivity.

How do we select it?

When selecting a pressure sensor, consider factors such as measurement range, accuracy, temperature range, response time, and compatibility with the fluid or gas being measured. Also, make sure the sensor is compatible with your existing control and automation systems.

How to install it?

Pressure sensors should be installed in the location where pressure needs to be measured, such as a pipeline or vessel. They should be mounted securely using appropriate fittings or adapters, and any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive the signals from a pressure sensor may vary depending on the specific device and building automation system. Typically, they will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
