Description
The differential pressure transmitter-controller E2408DF is a representative of the new line of multifunctional measuring instruments PluraSens®. The transmitter provides high accuracy and zero-level drift absence when measuring air pressure and non-aggressive gases.
Differential pressure measurement is carried out using a thermoelement operating on the principle of microthermoanemometry. Compared to membrane sensors, this technology provides a wider dynamic range, as well as higher stability of readings during long-term measurements and reproducibility of measurements, especially near zero values.
Connection of the transmitter to external devices is provided via the RS485 interface, operating on the Modbus RTU protocol and allowing direct connection of the transmitter to the Fieldbus network, as well as via analog outputs installed upon customer request.
