1. Touchscreen Color Paperless Recorder Temperature Measurement System for Cement Rotary Kiln Shell

   The color paperless recorder system measures and displays the temperature of the entire kiln at a rate of 36 scans per second. The continuously rotating surface of the kiln lining allows for evaluation of the reflective layer material's condition at all times. Even if a brick falls, the hot spot can be located during one rotation of the kiln. The color paperless recorder system automatically alarms for the high-temperature limit of a hot spot. The temperature profile of the rotary kiln shell indicates the internal heating status of the kiln, allowing for heater adjustments. Optional software features include tire slip monitoring and fan control.

   Application Advantages: Continuous monitoring of the entire surface; determination of the entire kiln shell temperature within one rotation; data optimization; scheduling of maintenance time; elimination of safety hazards; and avoidance of costly downtime.

2. Application of Color Paperless Recorders in Refractory Material Plants

   Temperature measurement and control are crucial in refractory material production; the quality of kiln temperature control directly impacts product quality. Especially in tunnel kilns, characterized by numerous temperature measurement points and long continuous operating times, poor temperature parameter control can lead to significant economic losses for production enterprises. Therefore, selecting appropriate temperature measurement methods is crucial for ensuring the normal operation of the kiln. Traditional temperature measurement methods for tunnel kilns are twofold: one is thermocouple measurement, which offers high accuracy and can be connected to paperless recorders or control systems for closed-loop control. Its disadvantages include short lifespan, especially in high-temperature kilns above 1300℃ where thermocouple consumption is extremely high, and the equipment is expensive, resulting in high operating costs. The second method is an optical pyrometer, which measures temperature based on the color of light emitted by the object being measured. Because it does not directly contact the high-temperature zone, it has a long lifespan, but its measurement accuracy is lower and susceptible to human error, leading to poor reliability. Applying infrared thermometers can effectively overcome these shortcomings.

   Color paperless recorders offer high measurement accuracy and, like thermocouples, output electrical signals for automatic recording and control. They also boast advantages such as long lifespan, simple operation, and low human error. Therefore, infrared thermometers are ideal temperature measuring instruments for high-temperature tunnel kilns. Infrared thermometers are commonly used in tunnel kiln applications, employing either single-point or multi-point switching temperature measurement schemes depending on user requirements. These are described below:

   • Single-point temperature measurement system: Each measurement point uses a single probe and an instrument box. The measurement unit acquires the temperature data. The 4-20mA analog signal output from each unit's instrument box is then connected to a multi-point recorder or control actuator. Data communication with computers, printers, and other devices is also possible via RS-232. This system typically uses high-precision, high-functionality instruments for its measurement units.
   • Switching temperature measurement system: This system connects the infrared probe signals installed at each measurement point to a single thermometer for signal processing. It outputs a 1-5V temperature signal corresponding to each measurement point for recording by a multi-point recorder. Temperature data can also be directly input into a computer via RS-232 for analysis and processing. Alternatively, the data can be printed directly from the instrument.

   Of the two solutions above, the single-point temperature measurement system, because each temperature measurement point has an independent temperature measurement and signal processing system, outputs real-time continuous analog and digital signals with fast response speed. It can be used as a real-time control signal for the control actuator to achieve closed-loop control. The multi-point switching temperature measurement system, while its output analog signal is also continuous, has a certain lag compared to the real-time temperature value. Therefore, it can only be used for data acquisition and recording, and is not suitable as a control signal. Its advantage is its better cost-effectiveness, reducing equipment costs in applications with less stringent requirements. In other refractory kilns, such as downdraft kilns and prism kilns, where there are fewer temperature measurement points, the single-point temperature measurement solution is more commonly used. Handheld infrared thermometers are also used, but these instruments can only perform intermittent sampling of kiln temperature, and each measurement and recording requires manual operation, making automatic continuous measurement impossible.

3. Color Paperless Temperature Recorders for Food Hygiene and Safety

   Monitoring temperature is crucial for ensuring food quality and safety, which is why professional food suppliers rely on paperless temperature recorders. These easy-to-use tools measure surface temperature without contact, preventing cross-contamination and damage to food. As a reliable and time-saving tool, paperless temperature recorders can complete temperature measurements in half a second. By providing rapid measurements of food surface temperatures, infrared thermometers can provide vital information about hazardous conditions, especially important considering that bacteria typically grow on food surfaces.

   For most critical equipment, non-contact thermometers provide instantaneous temperature readings. Raytek infrared thermometers can diagnose pipe leaks, supply and return gas temperatures, pipe artifacts, and other heat-related problems.

   Technicians can quickly and effectively obtain temperature data for the following applications:

   • Room temperature balance: Scanning walls to obtain unbalanced temperatures.
   • Piping Operation: Scanning the pipe surface reveals temperature spikes and locations of adiabatic differences.
   • Steam Distribution System: Diagnoses expansion or steam blockage from a safe distance.
   • Boiler Performance: Tests boiler performance by checking pipe temperatures.
