are blind temperature controllers with deviation
meter and without deviation meter respectively.
They are most rudged, reliable, economical and
widely accepted solution for Plastic moulding,
Laminating, Heat sealing &
Pharmaceutical machines. They are useful in many
other temperature applications like ovens, furnaces,
plants, Foundry etc.....
Thermocouple break protection.
On/Off or proportional
Attractive dial for setting
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.
: 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.
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.

2000D is with -20°C to +20°C deviation indicator
showing deviation between set and process temperature.
