Sitrans TW

Order No: 7NG3242-…..

SITRANS TW is a consistent further development of the hundred thousand times proven SITRANS T for the 4wire system in the mounting rail housing. Its many new functions set new standards in temperature transmitters. Its diagnostic and simulation functions provide the necessary clarity during commissioning and operation. Its HART®-interface makes the SITRANS TW easily adaptable to any measuring job with SIMATIC PDM.

Physical values can be preset with the simulation function. This enables testing of the complete signal path right as far as the control system without the need for tools. The drag pointer functions measure the system’s process variable minimum and maximum.

All SITRANS TW control room devices are available in non-intrinsically safe versions and intrinsically safe versions for applications under extreme conditions.

Benefits:

• Explosion protection [EEx ia] or [EEx ib] for measurements with sensors in the hazardous area
• Temperature-linear characteristic for all temperature sensors
• Temperature-linear characteristic can be selected for all temperature
  sensors
• Diagnostic functions
• Slave pointer functions

Application

The SITRANS TW transmitter is a four-wire rail-mounted device with a universal input circuit for connection to the following sensors and signal sources:

• Resistance thermometer
• Thermocouples
• Resistance-based sensors/potentiometers
• mV sensors
• As special version:
  • V sources
  • Current sources

The 4-wire rail-mounted SITRANS TW transmitter wire is designed for control room installation. It must not be mounted in potentially explosive atmospheres.

All SITRANS TW control room devices are available in a non-intrinsically safe version as well as in an intrinsically safe version for use with the most stringent requirements.
