Universal temperature transmitter
HART Field Device
The FlexTop 2222 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 an external RTD element can be used to compensate for „cold junction“ (CJC) if thermocouples are connected.The configuration is done with the FlexProgram, and the connection can be established using an USB cable directly mounted between the FlexTop and a PC.The FlexTop 2222 is embedded in silicone which makes it resistant to humid environments. It is ready for direct display mounting through UnitCom cable. Furthermore it has a 6.5 mm center hole for fast sensor replacement and spring loaded mounting screws which ensures a safe fastening even in vibrating environments.
*Programmable through integrated USB port
*Sensor calibration for either offset, slope or polynomial adjustment
*Accuracy better than 0.1°C for RTD elements
*Automatic cable compensation calibration (2-wire)
*Fast sampling time < 50 ms
