1Intelligent digital display measurement and control instrumentOverview

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

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.
