647-7 is a series 647 wet/wet differential pressure transmitter. It monitors differential pressure in air/liquid flow systems, HVAC automation, pneumatic systems and process control with the Series 647 wet/wet differential pressure transmitter. Units are temperature compensated and provide a 4-20mA output signal which can be interfaced with chart recorders, data loggers and computerized monitoring and control systems. Versatile for liquid or gas supports designs requiring more precise measurements in support of application. Temperature compensated improves performance of device for accurate measurement under different operating environments. Output signal provides capability to interface with automation systems to centralize monitoring.
