Importance of Pressure Sensor in HVAC System

HVAC pressure sensors are an integral part of most heating, ventilation, air conditioning and refrigeration (HVACR) systems. Not only does it help maintain a comfortable indoor climate, but it also increases the energy efficiency of the HVAC system. In addition, it enables the integration of HVAC systems with building automation systems. For more custom products from Lefoo, China leading  pressure transmitter manufacturer with many years experience with compliant with CE, Rohs, Reach, FDA, CQC certifications. 

1. The importance of HVAC pressure sensors

Traditional HVAC systems use pressure, temperature sensors and pressure control switch to control the basic operation of the system. For example, turning the system on or off, opening or closing valves or vents, etc.

As HVAC systems must become more efficient, there is an urgent need for more granular control of different subsystems. This has led to numerous technological advancements such as variable refrigerant flow, variable speed motors and blowers, electronic expansion valves, and numerous control methods for fine-tuning the system and reducing overall energy consumption.

Differential pressure sensor hvac play an important role in improving the energy efficiency of these systems by monitoring various parts of the system and ensuring that all of them are operating optimally. In fact, more and more HVAC pressure sensors are being installed in these systems to monitor this process and maintain accuracy. Reliability has become the key to ensuring data accuracy and consistency.

2. Application of HVAC pressure sensors

In Lefoo, The most common types of sensing in HVACR systems include temperature and pressure, and there is a growing trend to employ humidity sensors, gas sensors, and other sensing technologies. So what happens when these HVAC pressure sensors are not reliable enough?

Systems can fail, which can cost thousands of dollars in the worst cases. More often, HVAC pressure sensors failures result in system inefficiencies, erratic operation, and uneven control of the environment in the office or home.

In some cases, the system does not provide enough cold or warm air, which can cause personnel comfort issues, resulting in reduced productivity and equipment problems. At worst, when temperature is critical for computer equipment, food or drug preservation, organ maintenance, and more, system problems can lead to costly equipment failures and even loss of life. In addition, the services to diagnose and repair these problems are not only expensive, but also time-consuming.

While HVAC systems use a variety of onboard HVAC pressure sensors to monitor pressure in screens and air heating central systems, most pressure sensing is accomplished with heavy-duty pressure sensors. Refrigeration pressure sensor is used to monitor refrigerant pressure in compressor-based systems, the pressure of water or other liquids in large commercial chillers or other refrigeration systems.

The environments in commercial and residential HVACR systems are among the most challenging industrial environments. Due to large temperature fluctuations and high humidity, which are often accompanied by electrical noise, HVACR systems require HVAC pressure sensors that are robust enough to not only operate continuously, but also provide accurate and repeatable measurement readings.
