Chiller Temperature Controller : A special action for -50.0ºC to 50.0ºC range having independent setting for tember as well as delay time (time m for which Comres- sor has to rest before restarting) Hysteresis is also settable between 0.2ºC to 9.9ºC. The delay time is helpful in increasing the working life of the compressor. This is also available for two compressors ( independnet temperatures and the settings) and three compressors.Temperature Controller with Soak : For heat treatment apipilication addiptional time setting time setting is available to maintain the temperature of the furnace or ovan for the desired set time (0.999min) after the temperature has reached the set value.BOD Controllers : For controller of ovan temperature below or above m ambient temperature. The heating or cooling realy will turn on depending on whether wt temperature is above or below the ambjent temperature. Second sensior for sensing ambient temperature is provided. Both relays have independent hysteresis sellings (by keyboard).Temperature Controller With : The facilitynis used in heat treatment or settable rate of rise of temp material testing equipments .Rate of rise is settable by keyboard from 0 to 10ºC/minProfile Temperature Controller : This is useful in obtaining variable temperature profile in an ovan or furnace for heat curing application. The time and temperature data can be led by the keyboard, control action can be on/off or time propotional. this is also useful for testing purpose in Laboratory (Calibration Bath).PID Temperature Controller (Proportional, Integral & Derivative) : This is useful for precise control of temper ature in an ovan, furnce, plastic machinery etc. when job requires high heating during initial period & low heating when temperature stabilizes. Derivative action overcomes sudden changes in temperature due to load changes, integral action corrects the accumulated error.Derivative time constent and intergal time constant have to be set suitable for the machine whose temperaturemis to be controlled, initially, trial and error methodmis required to select these parameters, but once they are set the action gives better control of temperature.Relay output for control of contractor or pulse output for control of SSR is provided. Optionally 0 - 10V output can also be provided for control of SCR firing units.Controller with Analog Input : This is useful in application where transducers are used (i.e. load cell, flow sensor, pressure sensor etc.) The signal can be ) -10V or 4-20m A D.C. Like in other controllers, single set point and two point models are available. These relays can also be used as alternative settings, Calibration through key board is possible.
