Announcement capable of verifying high-precision temperature changes of 0.1℃
Real-time monitoring is possible via mobile devices.

Metis (CEO Park Ki-hyun) has built a business portfolio centered on the core areas of Index Units, Bake Units, and Robot Controllers for semiconductor front-end process equipment, as well as the production of Photo Full Lines (OEM production) for LCD equipment. Metis recently garnered significant attention by launching models developed through focused research on CC-Link and Auto Padlock.

Metis recently announced the MT99DK4 temperature sensor. The MT99DK4 was released as an NTC type designed to prevent electrical wiring fires caused by overcurrent in distribution panels.

In particular, since it can measure temperature simultaneously using a 3-channel NTC sensor, it can be used to measure the temperatures of circuit breakers and various parts within a distribution board. Furthermore, it enables high-precision temperature monitoring with a 0.1℃ change, and is equipped with a limit temperature setting function and individual monitoring capabilities for all three channels; if the temperature rises above the set level, a buzzer or alarm is activated. Notably, it supports Ethernet communication, offering the advantage of real-time temperature monitoring via an application.

The MT99DK4 operates at a rated voltage of DC 24V (80% of the rated voltage) and has a rated current ranging from a minimum of 20 mA to a maximum of 100 mA, typically consuming 50 mA. The temperature measurement range is 0–100°C, and with a temperature variation range of 0.1°C, it enables high-precision temperature monitoring. It supports 1-channel and 3-channel (optional) temperature sensor configurations and provides sampling every 1 second. It supports a total of two relay control outputs, including A contact and B contact, and the DAC current output is 4~20mA, and for the 3-channel model, Ethernet output is possible.
