电接点双金属温度计 WZPK-474S
中文介绍
电接点双金属温度计 WZPK-474S 是一款高精度、高可靠性的温度测量仪表。它采用先进的双金属片原理,通过两种不同膨胀系数的金属片焊接在一起,当温度变化时,金属片会发生弯曲变形,从而带动指针转动,实现温度的准确测量。该温度计具有测量范围广、精度高、稳定性好等特点,可广泛应用于工业生产、化工、电力、食品加工、制药等多个领域。
WZPK-474S 采用坚固耐用的外壳设计,能够有效抵御恶劣环境的影响,如高温、低温、潮湿、粉尘等,确保温度计在各种复杂工况下都能稳定运行。其电接点功能可实现温度的自动控制和报警,当温度达到预设值时,电接点会自动接通或断开电路,从而实现对设备的保护或对工艺过程的自动控制,大大提高了工作效率和安全性。
此外,WZPK-474S 的读数清晰,刻度精准,操作简单方便,易于安装和维护。无论是现场操作人员还是技术人员,都能快速上手使用。其良好的性价比也使其在市场上具有较高的竞争力,能够满足不同用户的需求。
English Introduction
The WZPK-474S bimetallic thermometer with electric contact is a high-precision and highly reliable temperature measuring instrument. It operates on the principle of bimetallic strips, where two metal strips with different coefficients of expansion are welded together. When the temperature changes, the metal strip bends, causing the pointer to move and accurately measure the temperature. This thermometer features a wide measuring range, high precision, and excellent stability, making it suitable for various applications such as industrial production, chemical processing, power generation, food processing, and pharmaceuticals.
The WZPK-474S is designed with a robust casing that can withstand harsh environmental conditions, including high and low temperatures, humidity, and dust. This ensures stable operation under complex working conditions. Its electric contact function enables automatic temperature control and alarms. When the temperature reaches a preset value, the electric contact will automatically close or open the circuit, protecting equipment or controlling the process automatically, thereby enhancing work efficiency and safety.
Moreover, the WZPK-474S has a clear reading, precise scale, and is easy to operate, install, and maintain. Both on-site operators and technicians can quickly get started with its use. Its good cost-performance ratio also gives it a high competitive edge in the market, meeting the needs of different users.
