Refrigerant Meter/Refrigerant Pressure Gauge Manufacturers

What are the main functions of the refrigerant pressure gauge?

In modern refrigeration systems, the ability to monitor refrigerant pressure changes in real time is essential. As an advanced monitoring tool, the refrigerant pressure gauge (real-time pressure monitoring system) can provide technicians with accurate data support, thereby effectively improving the operating efficiency and safety of the refrigeration system. Through the efficient readings of the refrigerant pressure gauge, technicians can gain an in-depth understanding of the flow state of the refrigerant in the system and then evaluate the overall working state of the refrigeration system. When the refrigerant pressure in the system is abnormal, the refrigerant pressure gauge will issue an early warning in time to remind technicians to take necessary measures to prevent potential failures.
Refrigerant pressure gauge is not only a monitoring device, but also an important assistant for fault warning and diagnosis. In the event of abnormal fluctuations in refrigerant pressure, the refrigerant pressure gauge can quickly capture these changes and help technicians identify potential problems in a timely manner. For example, if the refrigerant pressure is too high, it may indicate that there is a leak, blockage or other fault in the system; if the pressure is too low, it may indicate insufficient refrigerant or other abnormalities in the system. With the real-time data provided by the refrigerant pressure gauge, technicians can quickly locate the problem and take appropriate maintenance measures to ensure the normal operation of the refrigeration system.
In addition, ensuring the safe operation of the refrigeration system is one of the core goals of the refrigeration industry. The refrigerant pressure gauge can timely detect safety hazards in the system through real-time monitoring of refrigerant pressure changes, thereby effectively preventing safety accidents caused by abnormal pressure. At the same time, the refrigerant pressure gauge also provides accurate pressure data to assist technicians in reasonably adjusting the refrigerant charge to ensure that the system is always in the best operating state. This precise monitoring and adjustment not only helps to improve the safety of the equipment, but also significantly extends its service life.
In terms of improving system energy efficiency, the refrigerant pressure gauge also plays an indispensable role. By monitoring the changes in refrigerant pressure, technicians can evaluate the operating efficiency of the system in real time and make necessary adjustments according to the specific situation. For example, if the refrigerant pressure is found to be too high, the pressure can be reduced by adjusting the working state of the compressor or increasing the heat dissipation area of ​​the condenser, thereby improving the energy efficiency of the system. Conversely, if the pressure is too low, the pressure can be increased by increasing the refrigerant charge or optimizing the system's pipeline layout to further enhance the refrigeration effect.

What is the impact of the use environment on the performance of refrigerant pressure gauge?

The internal structure of refrigerant pressure gauge is complex and consists of multiple precision components, including spring tube, hairspring and pointer. The performance of these components is greatly affected by temperature changes. Therefore, the working environment temperature of refrigerant pressure gauge plays a vital role in its measurement accuracy and service life. According to JRL's experimental data, extreme changes in ambient temperature, whether too high or too low, will cause thermal expansion and contraction of internal components or material aging, which will directly affect the accuracy of measurement. Especially under extreme temperature conditions, the pointer of refrigerant pressure gauge may become stuck or drift due to thermal expansion and contraction, which will eventually lead to inaccurate readings.
In addition, the elastic elements of refrigerant pressure gauge, such as spring tube, may creep in high temperature environment, and long-term high temperature will cause permanent deformation, which will affect the accuracy of measurement. Therefore, JRL recommends that the use environment temperature of refrigerant pressure gauge be controlled within the range specified by the manufacturer, usually -25℃ to 55℃. For those RPGs that need to operate in high or low temperature environments, JRL provides specially designed products to meet customers' specific application needs.
Humidity and corrosive environments also have a significant impact on the performance of refrigerant pressure gauges. The components inside the refrigerant pressure gauge, especially the electronic components and seals, are susceptible to erosion by humidity and corrosive gases. Long-term exposure to a humid or corrosive environment may damage the sealing of the refrigerant pressure gauge, causing the internal components to rust or corrode due to moisture, thus affecting the measurement accuracy and service life. To this end, JRL's refrigerant pressure gauge products use high-quality materials and advanced manufacturing processes, with excellent moisture and corrosion resistance. However, in order to ensure the long-term stable operation of the refrigerant pressure gauge, users still need to avoid exposing it to a humid or corrosive environment for a long time. For those refrigerant pressure gauges used in high humidity or corrosive environments, JRL recommends that users take additional protective measures, such as installing a protective cover or dehumidification device, to ensure the reliability of the equipment.
In refrigeration systems, refrigerant pressure gauges are usually installed near equipment such as compressors and condensers, which will generate significant vibration and shock during operation. Under the influence of vibration and shock for a long time, the internal components of the refrigerant pressure gauge may become loose or damaged, resulting in reduced measurement accuracy or even failure. To this end, JRL has developed a series of seismic-resistant pressure gauges for vibration and shock environments. These products use specially designed shock-absorbing devices and reinforced structures to effectively resist the influence of vibration and shock, ensuring the measurement accuracy and stability of the refrigerant pressure gauge in harsh environments. For refrigerant pressure gauges that need to be used in vibration and shock environments, JRL recommends that customers choose the seismic-resistant pressure gauge series to ensure the safe operation and long-term stability of the system.
