Description LED single-loop pressure level controller temperature controller
Using advanced microprocessor for intelligent control, it is suitable for the display and control of various physical quantity detection signals such as temperature, humidity, pressure, liquid level, instantaneous flow, speed, etc., and can perform high-precision linearity on various nonlinear input signals. Correction measurement.
Using the latest jumper-free technology, the input port has single-channel and universal signal input functions, and a variety of input signals (various thermocouples, thermal resistance, standard voltage/standard current can be realized by simply selecting the instrument menu) signal), increasing the versatility and reliability of the instrument.
High-brightness LED digital display and high-resolution light bar display (proportional display) make the measurement/control value display clearer and more intuitive.
The input and output circuits are all optically isolated, with strong anti-interference ability. With serial communication interface, it can carry out two-way communication with various devices with serial interface to form a network control system.
With a variety of standard external dimensions, it can be applied to various measurement and control occasions. The whole machine adopts a snap-in structure, which makes the installation very easy
