Pressure Transmitters - Differential/HVAC

An HVAC switch is a simple yet elegant solution to monitor the electrical connection of an HVAC system. In a refrigeration circuit or compressor system, for example, the HVAC switch will be a high pressure one and a low pressure one. If anything trips either one of these HVAC switches the entire system will shut down. These standard pressure monitors are key to keeping an HVAC system fully functional. A HVAC switch is just one in a long line of pressure measurement tools offered through Davis Instruments. We carry standard pressure measurement as well as differential measurement for HVAC and clean room applications, including barometric measurement instruments. Industrial transmitters will have a very durable case to protect the electronics of the unit and even will have explosion cases for many applications, such as in oil and gas exploration and extraction. When not in a very dangerous industrial process, most industrial transmitters will have a stainless steel case to protect the unit from mild acids and slightly caustic applications. If you have questions about selecting an HVAC switch or other pressure measuring tools contact a Davis Application Specialist today.
