Temperature And Humidity Controllers For Dehumidifier DHU, Accuracy -1, Temperature Range 0-600 Deg C

Incorporates a microcontroller design design. Elegant appearance, User-friendly design and small-scale in size. Highly accurate and sturdy in operation. User programmable settingsdual display for simultaneous indication of t and rh. Field proven algorithm, Tested successfully for hvac control applicationsdescription libratherm offers pid controller model dth, 966, Dhu for controlling temperature t and relative humidity rh for the ahu and other similar hvac applications. For the proper functioning of the air handling unit, It is essential to oversee the t and rh of the air being supplied to the room or the hall. The t and rh values are to be when contrasted with the desired set values and derived from the error between the process values and set values the functioning of the hot/cold water valves/damper actuators, Heaters, Are controlled to preserve the t and rh aloft in the atmosphere flow. This model dth, 966, Dhu accepts inputs from standard t, Rh sensor or transmitter as given in the table below . The instrument simultaneously displays the temperature within the spectrum, 40. 0 to 60. 0oc and relative humidity in the variety of 0. 0 to 100. 0% rh. The pid outputs are offered in controlling temperature and %rh available in of 4, 20ma and /or among the structure of dc pulses. Common or individual elevated and ground-level alarm output for temperature and humidity may be supplied as per user s requirement. To accommodate unique dhu control application, The 3 way valve can function by 4, 20ma proportional pid in direct action to oversee the temperature and for the dc, Controlling rh pulse output is available, Which serves to control ac or dc operated solenoid valves or to control the heating for evaporation of moisture using libratherm make, Single or three phase thyristor control. Rs485 serial port can be found in interfacing to dcs or plc.
