Preface With the rapid development of the national economy, a large number of high-grade highways and railways have been built in recent years. Cement concrete components occupy an important position in bridge construction. Factors affecting the strength performance of cement components include: 1. Mineral composition of cement; 2. Additives; 3. Mineral admixtures; 4. Water content; 5. Cement concrete curing. The gradual setting and hardening of concrete after pouring is mainly due to the action of cement hydration. Hydration requires appropriate temperature and humidity conditions. Therefore, to ensure suitable hardening conditions and continuous strength growth, concrete must be cured. The purpose of concrete curing is twofold: first, to create various conditions for full cement hydration and accelerate concrete hardening; second, to prevent abnormal shrinkage, cracking, and other damage caused by exposure to sunlight, wind, and cold after concrete molding. Temperature monitoring plays a crucial role in the cement concrete curing process. This article introduces a multi-point wireless temperature monitoring system suitable for use in the cement curing room of a beam factory. System Composition: ☆ The JCJ100TW temperature sensor is encapsulated in a stainless steel metal shell and sealed with insulating and thermally conductive material inside. The products are characterized by their compact size, high sensitivity, wide variety, waterproof and shockproof design, and can be widely used for various types of temperature measurement, including ambient temperature, gas temperature, liquid temperature, object surface temperature, and freezing/refrigeration temperature.

Nominal Pressure: Atmospheric Pressure ☆ The JCJ500B intelligent temperature monitoring instrument adopts advanced hardware and software design, and can generally monitor 1 to 16 channels of temperature measurement signals. It can receive voltage, current, or other signals. The instrument can set various functions such as input signal, measurement range, alarm value, alarm hysteresis, error calibration, communication, and printing through internal parameter settings. The instrument can perform cyclic monitoring of various physical quantities such as temperature, humidity, pressure, liquid level, and flow rate. The JCJ500B intelligent temperature monitoring instrument can be used as a data acquisition device, and up to 100 instruments can be connected to work together. Through the supporting software or by the user developing a feature-rich data monitoring system according to the communication protocol, it can be used to monitor various physical quantities such as temperature, humidity, pressure, liquid level, and flow rate. Basic Parameters: Operating Power Supply: 90～265VAC (switching power supply) or 24VDC±10% Input Signal: Standard Current 0～10mA, 4～20mA, 0～20mA Standard Voltage 0～5V, 1～5V, 0～10V Thermocouples K, S, B, T, E, J, N, WRE Resistance Temperature Detectors Pt100, Pt1000, Cu50, Cu100 Measurement Accuracy: 0.2%FS±1 digit Display Range: -1999～9999 Display Method: Dual-row 4-digit LED display; upper row displays the measured value (0.8 inch), lower row displays the channel number (0.56 inch); LEDs indicate the alarm status of each channel (illuminated indicates alarm status). Temperature Compensation: Automatic compensation for cold junction temperature from 0 to 50℃. Alarm prompts for instrument range exceeding limits or input signal disconnection. Communication Baud Rate: 300–9600bps (internal freely settable). Communication Address: 0–99.
