(K3MA-L)
Application
• The K3MA-L monitors the temperature of an industrial furnace.
• The internal temperature of the furnace is measured with a thermocouple E52-
PR.
(The temperature range to be measured by E52-PR is 0-1,400 °C.)
• The unit of indicated values by the K3MA-L is "°C".
• When the internal temperature of the furnace reaches 1000 °C or lower than 800
°C, comparative output 1 is turned ON.
