Description

6351 Differential Pressure Transmitter - standard housing plastic by Testo

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 availability.

Measurement of differential pressure, flow velocity and volume flow
Automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term stability
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 commissioning and maintenance
Scalability of ±50 percent of the measuring range final value and free scalability within the measuring range
Configurable alarm management with adjustable response delay and alarm acknowledgement
