Differential pressure transmitters with high accuracy and long-term stabilty Measurement of differential pressure, flow velocity Automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term Plastic housing Display with multi-language operating menu and optical alarm display Ethernet, relay and analog outputs allow optimum integration into individual automation systems Self-monitoring of the transmitter and early warning function guarantee high system availablity The P2A software for parameterization, adjustment and analysis saves time and costs in Scalability of ±50 percent of the measuring range final value and free scalability within the measuring Configurable alarm management with adjustable response delay and alarm acknowledgement The differential pressure transmitter testo 6351 was developed specially for monitoring differential pressure in the measuring range from 50 Pa to 2000 hPa. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air. In order to keep the cleanroom conditions constant, the transmitter additionally calculates the parameters volume flow and flow velocity from the measured differential pressure. The testo 6351 is particularly outstanding thanks to the automatioc zero-point adjustment which ensures high accuracy and long-term stability. The integrated self-monitoring and early warning function also guarantees the operator high system • Differential pressure monitoring between Differential pressure monitoring in filling processes Monitoring differential pressure, volume flow and flow velocity in critical air conditioning technology
