High-Precision Pressure Measurement and Control: An Integrated Solution for Industrial Challenges

In modern industrial automation systems, pressure is not only an important process parameter but also a critical signal for safety interlocking and energy-saving control. Traditional pressure instruments often suffer from scattered functions and low integration, resulting in complex wiring, long commissioning cycles, and high maintenance costs. Nexisense YK-102 integrates measurement, display, transmission, and control functions into one compact unit. With a high-precision sensor and intelligent algorithms at its core, it provides system integrators and engineering contractors with a compact, stable, and easy-to-integrate pressure control solution.

Three Core Advantages

• Integrated Measurement and Control: Simultaneously achieves pressure acquisition, real-time display, analog output, and relay control, reducing instrument quantity and simplifying system architecture.

• High Precision and Wide Adaptability: Accuracy selectable up to 0.1%FS, supporting ranges from -100KPa to 10MPa, suitable for water, oil, and gas media.

• Flexible Communication and Strong Protection: Standard 4-20mA output and RS485 Modbus interface with IP65 protection, suitable for complex industrial environments.

Product Overview

Nexisense YK-102 Digital Pressure Transmitter Controller is a fully electronic intelligent digital pressure measurement and control product. It uses a high-performance imported pressure sensor from the United States, featuring a front-end oil-filled piezoresistive design with an isolation diaphragm. Through high-precision, low-temperature drift amplification circuits and an A/D converter, the pressure signal is converted into a digital signal processed by a microprocessor, achieving dual switching output control and analog output.

The product is easy to operate, flexible to configure, safe, and reliable. It is widely used in hydropower, water supply, petroleum, chemical, machinery, and hydraulic industries for precise pressure measurement, display, and control. As a key member of Nexisense industrial instruments, it ensures long-term stable operation with a robust housing and comprehensive protection circuits, making it an ideal solution for digital pressure management in industrial processes.
