Modbus-RTU sensors E'lemer AIR-20M2-MB

Microprocessor-based business class pressure sensors with Modbus RTU digital protocol based on RS-485 interface. Sensors with this digital protocol are easily and conveniently integrated into modern automated control systems (ACS). High polling rate of each sensor (up to 30 msec) and the high data transfer rate allows you to remotely collect all the necessary information on the measurement and technical condition of the surveyed devices. The sensors have a built-in LED indicator (SD) or a liquid crystal (LCD) indicator with backlight. For ease of visualization, the indicator has a rotation angle of ± 180°, the housing is 270°. The sensors have high noise immunity — EMC group — IV-A(B).
