Repair Swiss Danqing digital display meter

1、 Brand Overview: Danqing (usually referred to as "Danqing Electronics" or related companies) is a local instrument manufacturer in China, mainly focusing on the research and development, production, and sales of industrial process control display instruments

sale. Its products occupy a place in the domestic market with high cost-effectiveness, good stability, and strong practicality, and are widely used in various industrial sites. 2、 The core advantages of Danqing digital display are reflected in the following aspects: clear display: using high brightness LED or LCD display screen, the numbers are large and clear, making it easy to observe from a distance. Practical function: Multiple input signals: compatible with almost all industrial sensor signals, such as voltage, current (4-20mA), thermocouple (K, S, E, J, etc.), heat

Resistance (Pt100, Cu50), resistance, frequency, etc. Adjustable display range: The input signal can be linearly matched to actual physical quantities (such as temperature, pressure, flow rate, liquid level, etc.) through internal parameter settings. Alarm function: usually equipped with 1-4 relay alarm outputs, and can set alarm modes such as upper limit, lower limit, upper and lower limit. Transmission output: Some models can convert display values into standard 4-20mA or 0-10V signal outputs for use by other devices. Communication function: Many models support RS-485 communication interface, and with Modbus RTU and other protocols, can communicate with PLC, DCS, and other systems

Connect the machine or configuration software to achieve remote data collection and monitoring. Easy installation: Universal size: using internationally recognized panel openings

The dimensions (such as 48mm × 48mm, 72mm × 72mm, 96mm × 96mm, etc.) are convenient for installation on the control cabinet panel. Shallow depth: The instrument body is thinner, saving space inside the control cabinet. Strong anti-interference ability: Designed for the complex electromagnetic environment of industrial sites, it has good anti-interference performance to ensure stable and reliable readings. High cost-effectiveness: Compared to some international brands such as Omron and Siemens, Danqing watches meet basic industrial needs

Under the premise of seeking, the price is more competitive. 3、 The main product types of Danqing digital display meters have a rich product line, which can be mainly divided into the following categories: universal digital display meters; basic functions: the most basic data display and alarm output. Applicable: In various situations where sensor signals need to be converted into intuitive readings. PID control type regulator: Core function: Built in PID control algorithm based on display, can automatically adjust according to the deviation between the set value and the measured value

Output control (such as controlling heaters, cooling valves, etc.) to achieve precise temperature control. Applicable: Electric furnaces, ovens, injection molding machines, packaging machines, and other equipment that require constant temperature control. Multi channel inspection instrument: Core function: One instrument can display multiple input signals (such as 6, 12, 24, etc.) alternately, with high cost-effectiveness. Applicable: Systems that require simultaneous monitoring of temperature or pressure at multiple locations, such as temperature and humidity monitoring in computer rooms, multi-point temperature measurement in workshops, etc. Flow accumulator: Core function: specifically designed for flow measurement, it can receive frequency or current signals from flow meters, perform temperature and pressure compensation, accumulate flow calculation, etc. Applicable: Trade settlement or process measurement of steam, gas, and liquid. Energy meter/power meter: Core function: measure and display power parameters such as voltage, current, power, power factor, and electrical energy. Applicable: Distribution cabinets, power monitoring systems. 4、 Typical application areas: Danqing digital display meters cover almost all industrial scenarios that require data monitoring and control: the heat treatment industry: temperature control and display of electric furnaces, melting furnaces, and heat treatment lines. Plastic and rubber industry: temperature control for injection molding machines, extruders, and vulcanizers. Food and pharmaceutical industry: temperature monitoring of sterilization cabinets, fermentation tanks, and drying rooms. **HVAC (Heating, Ventilation, and Air Conditioning): Temperature and pressure monitoring of air conditioning units and chiller units. Water treatment industry: monitoring of pump pressure, liquid level, and flow rate. Temperature control and display of mechanical equipment packaging machines, printing machines, and textile machinery. Laboratory equipment: supporting instruments for ovens and test chambers. 5、 Clear requirements for selection and use: Firstly, determine what needs to be measured (temperature, pressure, etc.), what sensors to use, and whether control or communication functions are required. Confirm key parameters: Input signal type: must match the sensor output signal. Instrument size: Select according to the opening size of the control cabinet panel. Power supply: Commonly used are AC/DC 85-265V wide voltage or DC 24V. Additional functions: Do you need alarm output, transmission output, and communication interface. Correct installation and wiring: Strictly follow the instructions, separate the strong and weak signal wires to avoid interference. Parameter settings: Proper parameter settings must be made before use, including input signal type and range

Range, alarm values, etc. This is the key to ensuring the normal operation of the instrument. After sales service: Choose legitimate channels for purchase to ensure technical support and product warranty
