Baumer – FlexTop 2222

Temperature Transmitter

Brand : Baumer

The Baumer FlexTop 2222 is a universal, loop-powered temperature transmitter designed for industrial and OEM applications requiring precise and flexible signal conversion. Featuring HART® communication, this transmitter supports a wide range of sensor inputs including RTD/thermocouple/resistance and voltage, and offers customizable linearization and calibration for offset, slope or polynomial adjustments. Its universal design allows easy configuration via an integrated USB port or HART modem, enabling remote tuning and diagnostics in process automation systems.

Embedded in a silicone-resistant housing and compatible with DIN form B installation, the FlexTop 2222 transmitter provides reliable performance in humid or industrial environments. With a fast sampling time, galvanic isolation between input and output, and comprehensive configuration options (including automatic cable compensation), it delivers high-accuracy temperature measurement and loop signal conditioning that integrate cleanly with control systems and field networks.
