Yujie HJ-2825/1M Flow Measurement Transducer
Features & Applications
The Yujie HJ-2825/1M is a professional ultrasonic flow measurement transducer operating at 1.0 MHz with 0.25 MHz bandwidth for precise liquid flow detection. With 1500 pF static capacitance and an 8° beam angle, this transducer delivers wider coverage compared to the HJ-2112/1M while maintaining excellent sensitivity (-35 dB minimum).
Engineered for challenging industrial environments, it operates reliably from -20°C to 80°C and withstands pressures up to 1.8 MPa. Perfect for industrial flow monitoring, process control systems, water management applications, and manufacturing fluid control where accurate flow rate detection is critical. The wider beam angle makes it ideal for installations requiring greater measurement flexibility.
