WSG series intelligent temperature & humidity controllers
Summary&application:
WSG series intelligent temperature & humidity controllers are composed of two parts including display control instruments and sensors. The meter is extensively applied in electric power, building, petrifaction, agriculture and so on industries. It can take real-time measurement and fault alarm of the temperature & humidity of the measured environment. It can control the temperature & humidity of the measured environment within the specified range, to guarantee the safety and reliable operation of the devices by controlling external heaters and fans.
The meter conforms to country standard GB/T 13639《analog input digital indicators for industrial process measurement and control systems use》, JB/T 8386.1~2《analog input digital indicating controllers for industrial process measurement and control systems use》
1. Main functions and characteristics:
◆Adopting SCM data analysis control, analog and digital multiple filtering technique, it is characterized with high accuracy and strong anti-interference ability.
◆Digital tube display, small volume, complete function, beautiful appearance, button setting, easy operation, convenient installation and connection.
◆It has perfect self-checking and protection functions, displaying the indications when error occurs and closing the control.
◆It can monitor the temperature & humidity of the environment, with temperature rise/drop optional, cooling or dehumidifying through automatically starting the load to heat, to control the temperature & humidity of the environment within the required range.
