STT650 DIN rail mounted temperature transmitters offer high measurement accuracy, stability and reliability over a wide range of process and ambient temperatures.When you need high-accuracy temperature measurement in a panel / control cabinet. For applications with tight space constraints, since it’s DIN-rail mountable. In systems where noise / electrical interference is a concern (because of its galvanic isolation and surge robustness).
Their compact designs, along with dual channel options, help accommodate multiple temperature measurements on a panel, thus lowering both costs and inventory. Designed to deliver very high performance, the SmartLine STT650 easily meets the most demanding needs for temperature measurement, allowing it to replace virtually any transmitter available today. If you want cost-efficient redundancy: the dual-channel model helps reduce component count. When using common industrial protocols: HART, Fieldbus, or Profibus.
