Siemens Building Technology QBE3190UD25 Liquid Differential Pressure Sensor W/3-Valve Manifold 25 PSI 4–20mA

The Siemens QBE3190UD25 is a precision pressure difference instrument for measuring the difference between the pressure at two points in a liquid based system. This is a pressure sensor especially suitable for hydronic HVAC applications it’s capable of measuring pressure fluctuations between 0 and 25 PSI. The three valve manifold makes it easier to install and maintain. It acts on a simple basis. To accommodate control systems typically used in the HVAC industry, it converts the measured pressure differential to an electrical signal within a 4–20 mA range. This data is key to systems performance optimization, energy efficiency, and defect identification. QBE3190UD25 watches pressure differentials, helping the user maintain the pressure differentials to control water flows rates, balance system components, prevent equipment problems. Depending on the use, it is used in control valves, pump, heat exchangers, etc.
