Siemens releases head-mounted temperature transmitters

ATLANTA, October 23, 2006 – Sitrans TH devices from Siemens Energy & Automation, Inc. represent a new generation of compact, digital headmounted temperature transmitters. The new Sitrans TH devices are compact in design, which enables them to be installed in the sensor connection head.With accurate and secure transfer of the process temperatures, the new Sitrans TH devices are suitable for diverse measuring applications in the process industry, from chemicals and pharmaceuticals, to food and beverages, to power generation.The Sitrans TH 300 transmitter can communicate via Hart or Profibus PA and has galvanic isolation for thermocouple applications, while the Sitrans TH 200 and Sitrans TH 100 units are designed for stand-alone applications. The TH 100 transmitter can be used for simple applications requiring galvanic isolation using 100 Ohm RTD sensors.The new Sitrans TH temperature transmitters convert measured process temperatures to analog 4 to 20 ma output signals, or to digitally transmittable data via the Hart protocol. The Sitrans TH 300 transmitters are configured using PC with the Simatic-PDM system software or with a conventional standard HART communicator. The Siprom-T software tool is used for the stand-alone devices.The Sitrans TH 300 instrument has built-in characteristics for all commonly used temperature sensors and is applicable for most measurement applications. For special applications, a custom curve with up to 30 measured points can be specified using the characterization function. At startup, simulation functions carry out a system integrity test before the sensor elements are installed and connected with the transmitter. During operation, detailed self-test routines and monitoring functions indicate all deviations from standard operation. Additionally, a two-color indicator shows a green light for normal operation and a blinking red light in the event of a fault, such as a measured value outside the permissible range or a transmitter/sensor fault.About SiemensSiemens Energy & Automation, Inc. is one of Siemens’ operating companies in the U.S. Headquartered in the Atlanta suburb of Alpharetta, Ga., Siemens Energy & Automation manufactures and markets one of the world’s broadest ranges of electrical and electronic products, systems and services to industrial and construction market customers.
