DESCRIPTION :
The TC-403B Bargraph Indicator is a part of TC series
intelligent Microcontroller based Indicator instrument for
realization of economic solution of process control problem
It show process in and with bargraph to replace conventional
analog indicating instrument all the parameters are
programmable through front keypad. It is mostly used in:
* Primary & auxiliary temperature & data monitoring of
boiler.
* Iron & steel industries for soaking pits oxygen plate,
smelter plant.
* Sugar industry for Pan alternation, dailer automation.
* Chemical & petrochemical industry.
