Flextop 2211

Flex Top 2211 is a 4...20 mA loop-powered, configurable universal transmitter with galvanic isolation between input and output. The 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. Flex Top 2211 is embedded in silicone which makes it resistant to humid environments. The configuration can be established from the dedicated Flex Programmer configuring tool connected to a PC. Flex Top 2211 has a 6 mm centre hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments. A built-in temperature surveillance system gives alarm if ambient temperature limits are exceeded.
