Description
SITRANS TF420 Temperature Transmitter
Overview---SITRANS TF420
Our field devices for heavy industrial use
- HART, Universal
- 4 to 20 mA, universal
The temperature transmitter SITRANS TF works where others feel uncomfortable.
Benefits---SITRANS TF420
- 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.
- SIL2 (with order note C20), SIL2/3 (with C23)
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.
Function
Configuration
The communication capability over the HART protocol V 5.9 of the SITRANS TF with an integrated SITRANS TH300 permits parameterization using a PC or HART communicator (hand-held communicator). The SIMATIC PDM makes it easy.
For the SITRANS TF with integrated programmable SITRANS TH200, parameters assign with the PC. Available for this purpose are a special modem and the software tool SIPROM T.
Mode of operation
Mode of operation of SITRANS TF as temperature transmitter
The sensor signal, whether resistance thermometer, thermocouple element or Ω or mV signal, is amplified and linearized. Sensor and output side are electrically isolated. An internal cold junction integrate for measurements with thermocouples.
The device outputs a temperature-linear direct current from 4 to 20 mA. As well as the analog transmission of measured values from 4 to 20 mA, the HART version also supports digital communication for online diagnostics, measured value transmission and configuration.
SITRANS TF automatically detects when a sensor should be interrupted or is indicating a short-circuit. The practical test terminals allow direct measurement of 4 to 20 mA signals over an ammeter without interrupting the output current loop.
