Description
The WPCK03 diffused silicon pressure transmitter is a sophisticated device that starts with a high-precision imported diffused silicon pressure-sensitive chip. This chip, packaged using a mature production process, serves as the signal measuring element. It is then integrated with a highly reliable signal processing circuit and a wide temperature compensation mechanism. This combination allows the transmitter to maintain accurate measurements across a broad temperature range.
To ensure quality and performance, the product undergoes rigorous testing and screening of components, semi-finished products, and finished products. As a result, it can maintain a high precision standard signal output even at different temperatures. The WPCK03 offers excellent reliability, flexibility, and diversity, making it a popular choice for pressure measurement and monitoring in various industries such as water affairs, IoT, chemical, and petroleum.
With its multiple output methods, including I²C (for pressure and temperature), 4-20mA, 0.5-4.5V, and others, the transmitter can meet the different technical requirements of customers in various applications. Moreover, the company can customize pressure transmitters with different appearances and functions according to customer needs, providing more reliable and tailored solutions.
