PRODUCT DESCRIPTION
ALLEN BRADLEY 837-A2AX620 - RTD Temperature Sensor
This ALLEN BRADLEY 837 series Resistance Temperature Detector (RTD) sensor provides precise temperature measurement for industrial process control and monitoring applications. Utilizing a Pt100 sensing element in a 3-wire configuration, it delivers accurate and repeatable temperature data to programmable logic controllers (PLCs) and distributed control systems (DCS). Engineered for robust performance in demanding environments, it is suitable for machinery, fluid systems, and environmental monitoring.
