Digital Temperature Indicator / Controller employ the latest advance in electronics .This compact unit provides a clear
easy to read digital display with LED Digits measuring 10mm high 7 segment LED Display .
Principle of operation :- The sensor input is amplified by a low drift amplifier .This signal is fed to an Anolog to Digital
converter .The ADC displays the scaled temperature value on an LED display and compares it with the temperature set points
ON/OFF Control action The required temperature (set point ) is set on the digital display by turning the SET temperature
potentiometer ,with the set push button switch pressed . As long as the process temperature is below the set point the relay
is ON .When the temperature is reached to set temperature the relay is put OFF .This normally switches off the heating system
.As temperature drops the relay is swiched ON again
Applications It finds applications in the field of Petrochemicals,Fertilisers,Power stations, Sugar,Paper,Paint ,Chemical
,Glass and Metal industries .
