Product Details & Industry Applications
The DD Series Digital Dial Weight Indicator is a hybrid measurement solution that combines the clarity of an analog dial with the accuracy of a digital display. With its “Posi-Drive” analog pointer and backlit LCD, operators can quickly glance at weight data while still having access to precise digital readouts. This dual system makes the DD Series ideal for industries that require both fast visual checks and reliable data logging.
Available in multiple dial face sizes (6″, 8″, 10″, 12″, and 16″), the DD adapts to different environments and mounting requirements. It supports both traditional load cell mV inputs and 4-20 mA loop signals, allowing seamless integration into new or existing systems. Optional encoder inputs expand functionality further, enabling depth or speed monitoring in operations that need synchronized weight and motion data.
Durability is built in — the DD Series Digital Dial Weight Indicator operates from -20°F to 140°F (-10°C to +60°C) and is designed for use in dusty, cold, hot, or low-light environments. Field calibration is simple and quick, giving operators the flexibility to adjust settings without sending equipment back to the factory. With rapid sampling rates, the system responds instantly to changes in load, helping prevent overloading or unsafe operating conditions.

Industry Applications
The DD Series Digital Dial Weight Indicator serves a wide range of industries beyond wireline:
- Oil & gas rigs — monitor loads and ensure safe tool deployment and retrieval.
- Industrial lifting & hoisting — track weight in cranes, winches, and lifting systems.
- Wireline operations — monitor line tension and weight during downhole logging or interventions.
- Manufacturing & testing — use in labs or facilities requiring both analog and digital precision.
- Field service operations — deploy in mobile or off-grid environments thanks to its rugged design.
Frequently Asked Questions
Does the DD Series only work in wireline applications?
No — while it is widely used in oilfield and wireline work, its design makes it equally useful for industrial, lifting, and testing applications.
How do I choose the right dial size?
Smaller dials (6″-8″) are best for close-range installations, while larger dials (10″-16″) improve readability at a distance.
Can the DD connect to modern logging or control systems?
Yes. It includes RS-232 output (and optional dual ports) for integration with computers, controllers, or remote displays.
Is calibration complicated?
No — the unit supports field calibration, so you can adjust it on-site without downtime.
Why Choose the DD Series Digital Dial Weight Indicator?
For operations that require both visual clarity and digital accuracy, the DD Series delivers. Its hybrid dial + LCD design, flexible inputs, rugged construction, and fast response time make it an ideal solution for industries as diverse as drilling, manufacturing, lifting, and testing. With adaptability across multiple environments and applications, the DD Series provides reliable weight measurement wherever it’s needed.
