説明
The WPCK89 digital output pressure transmitter represents the next generation of pressure sensing technology. It is designed with a focus on high precision and reliability, making it an ideal choice for various applications. The transmitter features a wide voltage range, allowing it to operate under different power supply conditions, and has a low power consumption design. During operation, it consumes less than 2mA of current, and the standby current is as low as 1uA, which is highly energy-efficient.
The multi-level protection design of the WPCK89 enhances its anti-interference ability, enabling it to function stably in environments with electromagnetic interference or other disturbances. The standard IIC bus, with a maximum speed of 400K and a collection rate of 50 times/second, uses a standard IIC communication protocol. This makes it particularly suitable for integration with computer control systems, facilitating seamless data transfer and control.
The pressure seat of the WPCK89 is crafted from a single piece integrated structure of either 316L stainless steel or 17-4PH stainless steel. This design gives it high overload performance and a pressure interface without welds, silicone oil, or other organic substances, resulting in excellent sealing. The use of glass micro melting technology to firmly sinter the sensitive components of the sensor onto the pressure seat significantly improves the sensor’s resistance to high temperatures and vibrations. This ensures the long-term stability, reliability, and durability of the transmitter even in harsh industrial environments where extreme temperatures, vibrations, and other challenging conditions may be present.
During the standard purification production process, all parameters of the WPCK89 are strictly controlled. The entire product undergoes rigorous testing and aging screening of components, semi-finished products, and finished products. This meticulous quality control process guarantees the stable and reliable performance of the transmitter.
The WPCK89 digital output pressure transmitter can be applied in a wide range of fields where accurate pressure measurement is required. Its high precision, reliability, and digital signal output make it suitable for use in industrial automation systems, process control, environmental monitoring, and other applications where integration with computer control systems is necessary. Additionally, its ability to withstand harsh environments makes it a viable option for use in industries such as oil and gas, chemical processing, and manufacturing.
