Product Details & Industry Applications
The FHE-G Wireline Tension Monitoring Assembly offers oilfield and wireline operators a precision-engineered tool for monitoring line tension in environmental extremes and demanding field conditions. Designed for versatility, it features a wireline load cell and a compact wheel (sheave) assembly that installs easily into existing wireline setups. Sheaves are interchangeable to accommodate different line sizes (0.092″ up to 0.375″) without needing to disconnect the entire tool. Dual or single sheave configurations allow custom setups based on application, whether measuring single lines or grouped tensions.
An ultra-sensitive load cell responsive to even the smallest shifts in load makes this assembly ideal for operations where tension must be precisely tracked—such as logging, formation testing, or intervention. With a safe overload capacity of 100% and rated accuracy of ±0.25%, the FHE-G provides stable and reliable measurements. Operating over a wide temperature range (-40°F to 140°F, or -40°C to 60°C), it holds up in harsh climates, offshore rigs, desert environs, and cold-weather work. Compact and designed for ruggedness, yet sensitive enough for subtle variations, this assembly bridges the gap between durability and precision.
Key Benefits
- Interchangeable sheaves (0.092″-0.375″) for flexibility across line sizes.
- Ultra-sensitive load cell with ±0.25% accuracy for precise tension monitoring.
- Dual or single sheave configurations to match wireline system needs.
- Withstands extreme temperatures from -40°F to 140°F.
- Safe overload of 100% for durability under stress.
- Compact wheel assembly that allows line changes without full tool removal.
- Excellent performance even in severe climates and field conditions.
Industry Applications
The FHE-G Wireline Tension Monitoring Assembly serves a broad spectrum of oilfield and wireline industries. Typical use cases include:
- Wireline logging & formation evaluation — ensures stable tension during deployment and retrieval of logging tools.
- Service/supply vessels & intervention rigs — useful where constant changes in line size or load require adaptable sheave assemblies.
- Maintenance & safety-monitoring — monitoring tension to avoid slack, overstrain, or dangerous line behavior.
- Offshore platforms & extreme climate operations — rugged design allows functionality in corrosive, hot, cold, or humid environments.
- Calibration & testing labs — for accurate measurements during calibration and quality assurance of wireline gear.
Frequently Asked Questions
What line sizes are supported by FHE-G?
Sheaves are available to fit wireline diameters from 0.092″ up to 0.375″, and they are interchangeable to suit your specific configuration.
How accurate is the tension monitoring?
Rated with ±0.25% accuracy, making the FHE-G highly reliable for sensitive monitoring where even small load changes matter.
Can the assembly handle severe environmental conditions?
Yes. Designed to operate from -40°F to 140°F (-40°C to 60°C), resistant to climatic stress and rugged field use.
What happens if the load surpasses the rated capacity?
The assembly supports a safe overload of 100%, helping protect components during unexpected tension peaks.
Is re-routing or changing line sizes difficult?
No. The compact wheel/sheave assembly and interchangeable sheaves allow you to change lines without disconnecting the full tool.
Why Choose the FHE-G Wireline Tension Monitoring Assembly?
For oilfield professionals who need precise, adaptable tension tracking, the FHE-G Assembly is a well-rounded solution. It combines flexibility (in sheave sizes and line configurations), sensitivity (with ultra-accurate load cell measurement), and durability (with high overload tolerance and wide operating temperature range). Whether you’re deploying line over variable terrain, working offshore, or operating in extreme weather, FHE-G delivers trustworthy tension data to improve safety, reduce wear, and optimize performance.
