- 2, 3 or 4 wire sensors
- Accuracy better that 0.1°C
- 2 way configuration
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 confi guration and multiple process control in 2-wire networks. The configuration can be established from a standard HART® configurator or the dedicated FlexProgrammer confi guring tool connected to a PC. FlexTop 2221 is embedded in silicone which makes it resistant to humid environments. FlexTop 2221 has a 6 mm center hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments.
