The microprocessor-based technological meter-regulator is designed to measure and control temperature and other non-electrical quantities (frequency, pressure, level, etc.), converted into electrical signals of strength, DC voltage and active resistance to DC. ИРТ 1730D / M (D / А) are used as part of technological process control systems in various industries and at NPP facilities. The device displays digital values of the measured parameter and setpoints, and also has a three-color scale indication.
