VD 3-110 e 02.2010 Applications Temperature sensors are metrological components for heat or cold measuring points. They are used in pairs and measure the flow and return temperature of the heating or cooling system. The difference between the temperatures is used to measure energy consumption. Benefits • Matching hot and cold measurement components from Aquametro ensuring high accuracy over long periods of time. • Low inventory management with the same temperature sensors used for direct or sensor pocket measurement (DS/PSC) Temperature sensors and accessories for heat and cooling measurement points Features • A wide range of platinum resistance temperature sensors (as cable or head sensors) in different lengths for direct or sensor pocket mounting. • With Pt 100 or Pt 500 temperature sensors • Type approvals according to 2004/22/EC and PTB K7.2 (cooling, combined heating and cooling) • Matching accessories for direct mounting in the heating or cooling medium • Customised sensor pocket in various sizes
