Pressure Temperature Transmitter STT650 SmartLine DIN Rail High accuracy – 0.1 Deg C for RTD 4-20mA dc
Introduction
Part of the SmartLine® family of products, the STT650 is a DIN Rail mounted high performance Temperature transmitter offering high measurement accuracy, stability and reliability over a wide range of process and ambient temperatures. SmartLine easily meets the most demanding needs for temperature measurement applications.
Description
The SmartLine Temperature transmitter is designed and manufactured to deliver very high performance. The total accuracy level of the transmitter including the ambient temperature effect in, harsh industrial environments, allows the STT650 to replace virtually any competitive transmitter available today.
