ABB TTH200/TTH300 Head-Mount Temperature Transmitter
Product Description
Abbb Hart, Profibuspa Foundation Fieldbus Tth300 Head-Mount Temperature Transmitter
Head-mount temperature transmitter TTH300
The TTH300 is a two - channel temperature transmitter with HART, PROFIBUS PA, or FOUNDATION Fieldbus in two - wire technology. It has extensive functions and diagnostic options for all applications. It meets the highest requirements of temperature measurement with two sensor inputs, supporting sensor redundancy and sensor drift monitoring. The transmitter follows NAMUR recommendations such as NE 89 and NE 107. An LCD indicator with operating buttons can be connected as an option. It has various sensor error - calibration possibilities and offers accurate output signals. With global approvals for explosion protection, it is suitable for use in hazardous environments.
