Description
The Automation Components Inc (ACI) 135749 Pressure Gauge 0–300 PSI is an essential component sensor used in HVAC systems to measure fluid or gas pressure and convert it into a standardized 4–20 mA electrical signal for building controls or monitoring equipment. It is used in piping or pressure lines such as in hydronic heating, chilled water, or compressor circuits where pressure needs to be tracked. It is to provide accurate, exact pressure data to controllers or display units, enabling proper system regulation, secure responses, and performance monitoring.
