Libratherm offers Microprocessor based Humidity and Temperature Controller Model HTC-3003, which has same features as the Model HTC-3000, except that it has 3 digit display for simultaneous indication of both temperature and %RH value.
The controller accepts input from the standard (Pt-100) temperature sensor and from the capacitive type RH sensor or temperature/humidity transmitter. The process values and set values are displayed simultaneously in the range 0.0-99.90oC and 0.0 – 99.90% RH respectively on 4 independent 3 digit 7-segment Red LED displays,
Since the controllers are basically designed for the stability chambers, the accurate control of temperature and humidity is achieved by operating the air heater and the boiler heater in the PID control action. and the compressor is operated in ON/OFF action with time delay facility. Since the compressors are not required to be ON at certain level of temperature, the user selectable mode is provided to program the compressor operation in AUTO, Continuous ON or Continuous OFF mode.
The controllers are ready with the serial communication port RS 232 / RS 485 for interfacing to the computer for data logging and storage.
Specially designed window based E-Chamber Software does the on line data logging and plot the online / offline graph on the PC and also allows user to enter the set points and control parameters through PC and the controller. (i.e. bi-directional communication). Two level Pass Word protected (operator & supervisory) for unauthorized alteration of the set parameters and stored data is also provided.
