3.4 Temperature Monitoring/Control with Multi-level Output

Advantages of Using the K3HB-H
• The temperature inside the furnace can be monitored and multi-
level judgment outputs can be used to perform control outputs
according to the temperature inside the furnace.
• The temperature inside the furnace is detected using an E52-
PR@C Thermocouple.
• The temperature range of the E52-PR@C is 0 to 1,400ºC.
• The temperature is displayed in @@@.@ ºC on the K3HB-HTA.
(Can display temperature in increments as small as 0.1ºC.)
• The furnace temperature can be displayed using the 20-section
display on the position meter (provides a full-scale level display).
• Comparative output HH turns ON when the furnace is 1,000ºC or
higher. Comparative output H turns ON while the furnace is
between 800ºC and 1,000ºC. Comparative output LL turns ON
when the furnace is 200ºC or lower. Comparative output L turns
ON while the furnace is between 200.1ºC and 500ºC.
• The standby sequence function disables the comparative output
from the time the K3HB-HTA starts until the measurement value
reaches the PASS range.
