English Introduction
The WZP2-230B thermoresistor is a high-performance temperature measurement sensor widely used for temperature monitoring in power plants and other industrial applications. This product features a dual platinum thermoresistor design, capable of providing temperature data to two sets of display, recording, or control instruments simultaneously, meeting the needs of multiple devices for temperature measurement. Its temperature measurement range is from -200℃ to 500℃, which can meet the temperature measurement requirements in various complex environments of power plants.
The temperature-sensing element of the WZP2-230B thermoresistor is made of a platinum wire winding, which has good linear characteristics and high measurement accuracy. With a Pt100 scale, the allowable deviation of the B-grade precision is ±(0.3℃+0.005|t|), which can meet the requirements of power plants and other industrial scenarios for temperature measurement accuracy. The product adopts a waterproof junction box design, and the protection tube is made of stainless steel, which has good corrosion resistance and mechanical strength, and can effectively resist humidity and corrosion in the power plant environment.
In addition, the WZP2-230B thermoresistor is easy to assemble and replace, and the spring-loaded temperature-sensing element design makes it have good anti-vibration performance, which can work stably in environments with large vibrations such as power plants. Its fast thermal response time allows it to quickly respond to temperature changes and provide accurate temperature information to equipment in a timely manner.
