The Krohne OPTITEMP TT 22 R is a programmable 2-wire rail-mounted temperature transmitter. It works with a Pt100 RTD element in 3-wire configuration. The device features a robust design and excellent performance even under demanding conditions such as varying ambient temperatures, vibrations, moisture and radio interferences. It provides a temperature linear current output (4…20 mA). The OPTITEMP TT 22 R can be easily configured from a PC using the ConSoftTM software with configuration kit ICON. Thanks to the user-friendly interface, parameters like measurement range or failure indication can be set or re-set within seconds. Using PC configuration, no calibration is required. The temperature transmitter is designed to be mounted on a DIN rail. A dedicated head-mounted version is available with the OPTITEMP TT 22 C.
