The Baumer FlexTop 2221 is a 4...20 mA loop-powered, configurable universal transmitter with galvanic isolation between input and output.
Input can be configured for RTD or T/C sensors, resistance, current or voltage signals.
Either 2-, 3- or 4-wire connection can be selected for the resistance input. The built-in temperature sensor or a remote Pt100 sensor can be used to compensate for "cold junction" (CJC) if thermocouples are connected.
The HART® communication feature on-line process calibration and adjustment, transmitter configuration and multiple process control in 2-wire networks.
The configuration can be established from a standard HART® configurator or the dedicated FlexProgrammer configuring tool connected to a PC.
FlexTop 2221 is embedded in silicone which makes it resistant to humid environments.
It has a 6 mm center hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments.
