Series of industrial parameter display screens
1 Product Introduction
Series of large industrial display screens are mainly used in control rooms, workshops and other occasions. They are used for some important production data that people are more concerned about, such as power generation, product output, temperature, liquid level, flow consumption. The instantaneous cumulative amount of parameters such as coal volume is dynamically displayed in a large dot matrix or simulation graphics and has an alarm function, allowing the operator to clearly observe the actual value and status of the parameter from a distant location. This product adopts computer-controlled light-emitting screen display technology, using high-brightness light-emitting units and industrial-grade high-quality imported devices with built-in high-efficiency and high-power switching regulated power supply. The outer casing is carefully designed using high-quality aluminum alloy profiles or stainless steel. It has a flexible, clear and eye-catching display mode. Intuitive performance, stable and reliable features.
Two product features
Intuitive digital display accurately displays various parameters such as measured value accumulation value and set value
Strong alarm function The display can schematically display and issue an alarm when the measured value is low or exceeds the upper limit, etc. Signal, color change alarm can be realized
Simple operation function, range setting, alarm value setting and time calibration are realized by wireless remote control.
The installation methods include hoisting, embedding, wall-mounted, plate-top fixing, etc.
The time adjustment function clock can be adjusted through the communication interface. It can automatically convert between big and small months and leap years, has a built-in 100-year calendar, is not afraid of power outages, and has a continuous operation function.
The signal input is acceptable. When there are multiple signal inputs, each channel is equipped with an isolator to avoid instability caused by mutual interference between channels. The signal sent by the system can be accepted through the communication interface.
Due to the built-in microprocessor, the digital operation function can realize various functions such as square root calculation, nonlinear correction of the sensor, etc.
The time display can also display the number of safe production days (automatic accumulation).
The installation methods include hoisting, embedding, wall-mounted, ceiling fixing and other methods.
Three technical indicators
Working conditions ambient temperature ℃ relative humidity
Power supply voltage/
Analog measurement level/converter is bit, resolution is/high measurement accuracy
Alarm output relay contact type or non-inductive load.
The display channel or other standard signals can be measured at the same time, and the display range can be set arbitrarily by the remote control. When the number of measurement channels is greater than the number of channels, you can use the programmable inspection instrument produced by our company, which accepts various input signals (thermocouple, thermal resistance, etc. can be selected arbitrarily), and the display range can be set arbitrarily on the meter. The communication interface of the meter sends the measurement data to the industrial parameter display to realize the measurement and display of multi-channel parameters.
The data sent by the system can be accepted through the interface communication protocol), and the parameter display color and decimal point position can be set. The display screen is set according to the order content format
Five-terminal wiring
Note that the terminal is an analog input (~) terminal, which can be increased or decreased according to the actual number of input channels. It is a power supply and alarm terminal. When there is no alarm, there is no Alarm terminal. It is the communication interface.
