Recently, Honeywell has introduced the new PX3 series of heavy-duty pressure sensors for HVAC and refrigeration equipment. The sensor family helps industrial HVAC and refrigeration equipment manufacturers better monitor pressure and operating conditions in equipment systems, thereby reducing energy efficiency losses associated with equipment.
In the harsh environment of the refrigeration system, Honeywell PX3 series sensors can maintain stable operation under the external temperature range of -30 ° C to 50 ° C, and have excellent performance in insulation resistance, dielectric strength and frost resistance. . At the same time, PX3 series sensors can work stably in electromagnetic environments such as wireless signals, radio frequency (RF) communications, and electronic devices.
In the temperature range set by HVAC and refrigeration equipment, the monitoring accuracy of the sensing device determines whether the sensing signal is true, comprehensive, clear and valuable. Honeywell's PX3 series sensors have a total error range (TEB) that does not exceed 1%, helping field managers better optimize building automation control systems and efficiency.
In addition to its use with common hydrofluorocarbon (HFC) refrigerants, Honeywell's PX3 series sensors are also suitable for many new generations of refrigerants that may help slow down global warming as well as oil, lubricants, air, water and Hydraulic oil, etc. The PX3 series of sensors can be used in a wide variety of environments including compressors, rooftop chillers, and cold storage in grocery stores; potential applications are also used in the heavy-duty transportation industry, air systems, and hydraulic oil pressure monitoring.
Joshua Edberg, Director of Global Business, Sensors, Honeywell Sensing and Productivity Solutions, said: "HVAC companies and building operators are very concerned about reducing energy costs and improving building automation. Honeywell's next-generation PX3 series of heavy-duty sensors Durable and consistently precise, this will allow customers to produce products with superior performance and will help them achieve optimal performance at a reasonable cost range."
