Welcome to Cangzhou Dean Safety&Special Tools Co., Ltd – a trusted manufacturer established in 2001 with an annual export value exceeding US$100 million. We are pleased to introduce our Ball Tip Sounding Rod with 4-20mA Output, 0-5m Range, Stainless Steel Probe for Level Sensing. This innovative instrument combines rugged construction with precise electronic output, making it an ideal solution for continuous level monitoring in tanks, wells, and reservoirs. Designed for long-term reliability, the stainless steel probe withstands harsh environments while delivering a standard 4-20mA signal for seamless integration with PLCs, SCADA systems, and remote displays. Whether you are measuring water, wastewater, or other compatible liquids, our sounding rod offers accurate readings with minimal maintenance.
As a manufacturer with extensive experience exporting to over 20 global markets including North America, Europe, Southeast Asia, and the Middle East, we understand the importance of quality and consistency. Our ball tip design eliminates clogging and ensures stable contact with the liquid surface, while the 4-20mA output provides real-time level data unaffected by distance. Below, we detail the key features and technical specifications that set this product apart.
Key Features & Benefits
- Stainless Steel Probe: Made of 304 or 316L stainless steel for corrosion resistance and durability in water and chemical applications.
- Ball Tip Design: Prevents sediment accumulation and ensures accurate level detection even in turbulent or dirty liquids.
- 4-20mA Output: Industry-standard analog signal enables easy connection to most controllers and data loggers without signal conversion.
- 0-5 Meter Measurement Range: Covers common tank depths; custom ranges up to 10 meters available upon request.
- High Accuracy: Optional ±0.5% full scale accuracy for demanding applications (specify when ordering).
- Flexible Cable Options: Standard polyurethane or PTFE-jacketed cable with customizable length; optional vented cable for submersible use.
- Wide Operating Temperature: -20°C to +80°C suitable for most indoor and outdoor environments.
- Low Maintenance: No moving parts, simple installation, and long service life reduce total cost of ownership.

The ball tip sounding rod is particularly effective in applications where floating debris or viscous liquids might otherwise cause false readings. Its rigid stainless steel construction allows for direct immersion, and the 4-20mA output can be transmitted over long distances without signal degradation. For tanks with limited access, the rod can be installed through a 2-inch (or larger) opening, making retrofitting straightforward.

Frequently Asked Questions
-
What liquids can the sounding rod measure?
It is compatible with water, wastewater, light oils, and many chemical solutions. For highly corrosive media, we recommend the 316L stainless steel version. Please consult our sales team for specific chemical compatibility. -
Can the 4-20mA output be directly connected to a PLC?
Yes, the standard 4-20mA signal is compatible with most PLC analog input modules, as well as data loggers and panel meters. No additional converter is needed. -
Is the probe submersible?
The standard model is designed for immersion up to 5 meters. With the optional IP68-rated cable and sealing, it can be used in submersible applications. We do not recommend constant submersion beyond 10 meters without consultation. -
How accurate is the level measurement?
Standard accuracy is ±1% of full scale. An optional ±0.5% FS accuracy upgrade is available for applications requiring higher precision. -
Can the cable length be customized?
Absolutely. We offer cable lengths from 2 meters to 20 meters. For longer distances, please inquire about signal boosting options. -
What is the minimum tank depth required?
The dead zone (minimum measurable level) is approximately 10 cm from the probe tip. For very shallow tanks, a modified design may be required. -
Does the ball tip require regular cleaning?
The ball tip is self-cleaning in most applications. However, in sticky or heavily fouled liquids, periodic manual cleaning may improve accuracy. Maintenance intervals depend on the specific medium. -
Do you provide international shipping?
Yes, we ship worldwide from Tianjin, Shanghai, or Ningbo ports. Our logistics partners ensure safe and timely delivery to over 20 major market regions.
For more information or to place an order, please contact our sales team. We are committed to providing high-quality level sensing solutions that meet your exact requirements.
