SITRANS TH200 and SITRANS TH300 transmitters are suitable for all industrial sectors. Their compact design allows installation in connection heads of type B (DIN 43729) or larger. Universal input stage supports:

• Resistance thermometers
• Thermocouples
• Resistance-type transmitters/potentiometers
• DC voltage sources

The measurement signal from resistance-type transmitters (two-wire, three-wire or four-wire connection) or thermocouples is converted to digital format, processed by microcontroller, corrected according to sensor characteristics, and transmitted through electrical isolation. The processed value is converted to 4-20 mA output current. Parameters are configured via PC with coupling module (SIPROM T modem or HART modem) or HART communicator for SITRANS TH300 models.
