Description
The miniature differential pressure transducer IZMERKON DD-10 is a MEMS device based on a silicon microchip.
After automatic temperature compensation, linear correction, signal amplification, voltage conversion, and other types of signal processing, a standardized 4…20 mA and RS485 output or other optional signals are provided.
The device also features protection against voltage spikes and reverse polarity, which enhances product reliability, while system stability and high performance are ensured by using temperature compensation functions and digital calibration.
For pressure transducers of this series, two types of isolation are provided: the first type is used for measuring differential pressure of non-aggressive gases in ranges up to 5 kPa, the second type is suitable for measuring pressure of non-aggressive media in ranges above 5 kPa using stainless steel materials and sealing rings.
