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
