FlexTop 2221 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. 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 Flex Programmer configuring tool connected to a PC. Flex Top 2221 is embedded in silicone which makes it resistant to humid environments. Flex Top 2221 has a 6 mm centre hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments.

4...20 mA transmitter with HART® communication. RTD, T/C, mV and R inputs Isolation voltage 3.75 kVac Configuration via Flex Programmer Accuracy better than 0.1°C (Pt100) Configurable linearization damping and status indication Local, remote or fixed compensation for "cold junction" (CJC) Transmitter temperature alarm Ex approvals: Demko EEx ia IIC T5/T6, ATEX II 1G FM Class 1, Div 1, Groups A, B, C, D
