説明
The WPCK08 piezoresistive liquid level transmitter is a specialized product designed to meet the unique requirements of liquid level measurement and control in potentially hazardous environments. Its stainless steel corrugated hose design serves as a safeguard for the cables, ensuring their longevity and reliability even in challenging conditions. The dedicated amplification and adjustment circuit is a key component that enables the transmitter to effectively deal with corrosive liquid media and accurately measure the liquid level in open tanks. This circuit also provides the flexibility of multiple output signals, making it easier to integrate with different systems.
The split input structure of the WPCK08 is another notable feature. The liquid input utilizes an OEM pressure sensor with isolation, which guarantees high precision and excellent stability in measurements. The external explosion-proof junction box or instrument housing houses the circuit output part, equipped with built-in wiring terminals for straightforward and rapid operation. With various installation methods available, such as input type, plug-in thread, and flat flange, the transmitter can be conveniently installed according to different application scenarios. The front-end sensor’s IP68 protection level further enhances its durability by providing excellent protection against dust and water immersion.
The WPCK08 explosion-proof liquid level transmitter boasts a small size and light weight, making it easy to install and transport. Its good long-term stability ensures consistent performance over time, reducing the need for frequent maintenance. Manufactured in strict accordance with the ISO9001 international quality assurance system, the product meets high-quality standards. It is suitable for measuring various liquid media that are compatible with stainless steel and finds applications in a wide range of industries, including petroleum, chemical medicine, metallurgy, power plants, mines, industrial sewage treatment, urban water supply and drainage, and hydrological exploration.
Moreover, the WPCK08 complies with GB 3836.1-2010 and GB 3836.4-2010 standards, carrying the explosion-proof label Ex db IIC T6 Gb. This makes it suitable for general explosive gas environment conditions and gives users confidence in its safety and reliability. It has also been reviewed and qualified by the National Quality Supervision, Inspection and Testing Center for Explosion proof Electrical Products, further validating its quality and performance.
