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.
