SIEMENS SITRANS Temperture Transmitters (Field Mounting)

SITRANS TF is available in your choice of a rugged die-cast aluminum or durable stainless-steel housing. It measures signals from resistance thermometers, resistance-type sensors, thermocouples and voltage sensors, and converts the signal into direct current signal or bus signal (Profibus PA or Foundation Fieldbus) in accordance with the sensor characteristics.

The SITRANS TF280 is a field temperature transmitter that transmits the process value per Wireless HART communication.

The field transmitter for rugged industrial environments.

Because of its IP67 protection, SITRANS TF is used in environments too tough for other transmitters.

It measures signals from resistance thermometers, resistance-type sensors, thermocouples and voltage sensors, and converts the signal into direct current signal (HART) or bus signal (Profibus PA, Foundation Fieldbus or Wireless HART) in accordance with the sensor characteristics

SIEMENS SITRANS TF HEAVY DUTY Temperature transmitter

The SITRANS TF is a highly robust transmitter designed to handle challenging environments, boasting an IP67 rating. Constructed from durable die-cast aluminum or long-lasting stainless steel, it excels at transforming resistance thermometers, thermocouples, Ohm and mV signals into a load-independent DC current or a digital signal according to Fieldbus standards like Profibus PA or Foundation Fieldbus. The remote-mounted sensor prevents overheating at high temperatures and eliminates vibrations and oscillations associated with long neck tubes and protective pipes. This flexibility allows for easy access and display of measured values on the programmable digital display. Additionally, the SITRANS TF can be used without a transmitter as a versatile field display unit for all 4 to 20 mA signals. Models are available in intrinsically safe or explosion-proof versions, catering to various application requirements

SITRANS TF is an IP67 field transmitter for heavy industrial use. It transforms resistance thermometers, thermocouples, Ohm and mV signals into a load independent DC current corresponding to sensor characteristic or a digital signal according Fieldbus standard Profibus PA or Foundation Fieldbus.

Application

SITRANS TF can be used everywhere where temperatures need to be measured under particularly adverse conditions, or where a convenient local display is ideal. Which is why users from all industries have opted for this field device. The rugged enclosure protects the electronics. The stainless steel model is almost completely resistant to sea water and other aggressive substances. The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options.

Benefits

Universal use
- as transmitter for resistance thermometer, thermocouple element, Ω or mV signal
- as field indicator for any 4 to 20 mA signals
Local sensing of measured values over digital display
Rugged two-chamber enclosure in die-cast aluminum or stainless steel
IP66/67/68 degree of protection
Test terminals for direct read-out of the output signal without breaking the current loop
Can be mounted elsewhere if the measuring point
- is difficult to access
- has high temperatures
- experiences vibrations due to the process cell
- is to avoid long neck pipes and thermowells
Can be mounted directly on American-design sensors
Wide range of approvals for use in potentially explosive atmospheres. Types of protection "Intrinsically safe, non-sparking and flameproof", for Europe and the USA.
