1Intelligent temperature and humidity digital display controllerOverview

This series of products adopts surface packaging modular technology, greatly improving the anti-interference ability of the instrument. It has functions such as display, control, transmission, communication, and universal signal input. It is suitable for displaying and controlling various physical quantity detection signals such as temperature, humidity, pressure, liquid level, instantaneous flow rate, and speed, and can perform high-precision linear correction on various nonlinear input signals. It can be widely used in fields such as electricity, metallurgy, chemical industry, petrochemicals, paper printing and dyeing, brewing, tobacco, aerospace bases, etc.

By adopting jumper free technology, the input port has universal signal input function. By changing the internal parameters, it is possible to easily switch between multiple input signals (various thermocouples, thermal resistors, remote pressure, mV, standard voltage/current signals). The circuit board has been optimized in design and continuously improved in production process, reducing temperature drift and enhancing anti-interference performance to ensure the stability and reliability of the product during long-term operation. Using high brightness LED digital display and high-resolution light column display (proportional display) to display measurement/control values

Show more clearly and intuitively.

All output circuits adopt optoelectronic isolation, with strong anti-interference ability. It can be equipped with a serial communication interface and can communicate bidirectionally with various devices with serial interfaces to form a network control system. It has multiple standard external dimensions and can be applied to various measurement and control scenarios. The whole machine adopts a snap in structure, which is very easy to install.
