PControl - ewidencja czasu pracy, pomiar temperatury

Product description

REM-81 is microprocessor (temperature and humidity) controller designed for professional dryers of tobacco or other farming products. It can be used in modern dryers using oil or gas fuels.
REM-81 has many control  functions to secure appropriate drying process and excellent  quality of final product.
User can set drying program in detail, controlling temperature and humidity changes, burner, fan and throttle operation.
Every drying program  is divided  into steps  (max.  10 per  program).  Those steps specify  temperature, temperature difference speed and air  humidity based on psychrometric difference  (difference between temperature  measured   with   2   thermometers:   dry   (T1)   and   wet   (T2).  ΔT=T1-T2   or   other   humidity
transducer)
Typical   programs   consist   of   5   basic   steps:   yellowing   (2   steps),   leaf   blade   drying,   vein   drying,   and  humidification. Controller allows to configure and modify up to 10 programs.
Some programs have defined step durations,  when others are set  for 999h and allow user  to  terminate  program steps according to leaves state. This gives flexibility and helps to achieve best quality product.
During automatic operation controller carries out all program steps. User’s role is to watch drying leaves and manually adjust some program steps.
Controller can also be set to fixed set-point operation. In this mode user has to enter control parameters in the right moments of drying process and control fan and humidification manually. User can watch process duration.
Optionally REM-81 controller can be equipped with RS485 or  infrared communication  interface  to allow computer connection.
Front panel parts: 4 control buttons, 4-digit display, 5 LEDs
