3-2 Monitoring the Internal Pressure of a Tank
(K3MA-J)
Application
• The K3MA-J monitors the internal pressure of a tank.
• The internal pressure of the tank is measured with a pressure sensor E8AA-M10.
(When the pressure is 0-980 kPa, current of 4-20 mA is generated.)
• The unit of indicated values by the K3MA-J is "kPa", and the values are indi-
cated to one tenth’s.
• When the internal pressure of the tank reaches 550 kPa, comparative output 1 is
turned ON.
• When the internal pressure of the tank decreases to 100 kPa, comparative output
2 is turned ON.
