Rail-mount, two-wire temperature transmitters

Designed to be DIN-rail mounted the two-wire, loop-powered temperature transmitters need no additional power supply.

The Sitrans TR200 and the Sitrans TR300 are two-wire temperature transmitters designed for rail mounting. When connected in the 4-20 mA loop, these devices need no additional power supply. The Sitrans TR200 temperature transmitter is configured using a PC, and the Sitrans TR300 transmitter can be configured using a HART interface. Both devices feature a diagnostics LED that indicates the function status, which quickly detects open or short circuits so they can be corrected. This feature is useful when dealing with a large number of measuring points. The temperature transmitters support all standard RTDs and thermocouples, as well as resistance and voltage inputs. The DIN-rail mounting system means that the transmitters can be set up and maintained in a central location away from harsh environmental conditions.
