Temperature Sensor NM140 Series

Product Overview

The NM140 is a temperature transmitter with a wide measurement range. It utilizes thermocouples or PT100 thermal resistors for temperature measurement. The signal is processed by the rear processing circuit and converted into a standard industrial electrical signal for output. The all-metal housing design allows this series of products to be used in various industrial occasions. HART output is optional. The electronic head part can be rotated, enabling users to adjust the cable outlet direction as required.
