SITRANS T Temperature Measurement Field Transmitter
SITRANS TF320/420
As single and dual chamber
The field transmitter can be used for all common resistance thermometers and thermocouples. Resistance-type sensors and millivolt signals can be analyzed, too. The configuration can be done quick and easy via SIMATIC PDM, handheld communicator or the optional display with push buttons. Both temperature transmitters SITRANS TF320 as well as TF420 stand for reliability, accuracy and robustness.
Key Features
- The two independent sensor inputs of the SITRANS TF420 include a 4-wire sensor connection with a hot backup function, which guarantees true reliability.
In case of a sensor failure, the transmitter switches seamlessly to the second sensor, the values will continuously be recorded without any data losses. - The sensor calibration according to the Callendar-van-Dusen method plus the additional sensor drift detection (only TF420) ensures high accuracy, accelerated calibration time and optimal calibration planning.
- The SIL2 / 3 certification in conjunction with a variety of Ex approvals is the perfect solution for your safety-critical applications, even under the most extreme conditions down to -50 ° C.
- The service-friendly details make the SITRANS TF320/420 unique: with help of a millimeter the value of the 4..20mA loop can be read directly, without interrupting the output signal.
- Thanks to the HART 7 ability, further diagnostic data can be transferred directly to the maintenance staff or, can be read, alternatively, directly at the display with push buttons, due to the NE107 conform diagnostics alarm.
