DIN Rail Mounting, thumbwheel switch setting and
low cost Temperature Controller.
Working:
Temperature
required is to be set on high resolution attractive
dial. Instrumentation amplifiers linearises external
variable (t/c or Pt-100) & set point temperature.
Error amplifiers compare set and actual temperature
and gives command to relay driving circuit. Control
action of relay can be On-Off or Time proportionating
depending on heat inertia of the system.
On-Off Control
: In this type relay is on upto the set temperature
& cuts of at the set Point. System temperature
will come down & again relay will go on at
temperature 2°C below the set point. Same
function is repeated.
Time Proportionating
Control : In this type relay will be On &
Off is band of ±2°C of set point. On
& Off time will adjust as per the heat requirement
of the system. Of course total time cycle will
be of 15 seconds. We also offer band & cycle
time as per the application.
