Universal Temperature Transmitter NM121 Series

Product Overview

The NM121 is a temperature transmitter with a wide measurement range. It uses a thermocouple or PT100 thermal resistor for temperature measurement, and the signal is processed by the rear processing circuit and converted into a standard industrial electrical signal output. The all-metal housing design enables this series of products to be used in various industrial occasions. HART output is optional. Users can choose to install an LED or LCD digital display according to their requirements.
