Jiwei Introduces Advanced NAMUR Output Tuning Fork Liquid Level Switch

Jiwei has introduced a new model of tuning fork liquid level switch—the NAMUR output Tuning Fork Liquid Level Switch. This innovative product is designed to meet the needs of customers looking to update or replace their existing NAMUR output Fork Level Switches previously imported from Europe. Until now, no Chinese manufacturer supplied NAMUR output Fork Level Switches, making Jiwei’s launch a significant development that fills this market gap and provides a more convenient and cost-effective option for customers.

Key Features and Benefits of Jiwei NAMUR Output Tuning Fork Liquid Level Switch

Similar to the 4-20mA two-wire output, the NAMUR output is also a two-wire system, but it operates with a smaller current and lower power consumption. Both NAMUR and 4-20mA output instruments can be used in Intrinsic Safety explosion protection areas, with power supplied through a safety barrier.

• Safety Considerations: Although the NAMUR output switch can replace the 4-20mA two-wire output switch, the signal output specifications differ. The 4-20mA output operates at 10-36V and 8mA/16mA, while the NAMUR output operates at 8.2V, with current output equal to or lower than 1.2mA and equal to or higher than 2.1mA.
• Power Efficiency: The NAMUR output switch’s lower power consumption and small current supply make its design and interference resistance more complex than the 4-20mA output switch.
• Cost Considerations: Due to these complexities, the NAMUR output tuning fork liquid level switch is more expensive in terms of instrument configuration and safety barrier requirements compared to the 4-20mA two-wire output switch.

Performance and Competitiveness

Jiwei’s NAMUR output Tuning Fork Liquid Level Switch offers competitive performance, matching the safety, stability, and interference resistance of European imports. This new product exemplifies Jiwei’s commitment to innovation and customer-centric solutions.

Conclusion

Jiwei’s launch of the NAMUR output Tuning Fork Liquid Level Switch represents a significant advancement in level measurement technology in China. By providing a reliable and cost-effective alternative to imported switches, Jiwei continues to support its customers with high-quality and innovative products.
