Product Details & Industry Applications
The MHD-47 Wireline Measuring Head is a precision tool designed to provide accurate measurement of both line tension and line payout in wireline operations. Ruggedly engineered for oilfield environments, this measuring head is an essential component for wireline service companies, logging contractors, and production teams that demand dependable cable measurement under the toughest conditions.
Constructed with a combination of aluminium and stainless steel, the MHD-47 delivers exceptional durability while keeping the frame lightweight enough for ease of handling. Its heavy-duty rollers are fitted with grease fittings for smooth operation, reducing wear and extending service life even in harsh drilling and logging environments. Strong clamping springs ensure positive line tracking and minimize slippage, making every measurement more reliable.
The system supports a wide range of wireline sizes, from 0.081″ up to 5/16″ diameter, and can be configured for either top-mount or bottom-mount installation depending on your rig requirements. A hinged mounting shaft allows for quick installation and adjustment in the field, reducing downtime and improving operator efficiency. Operators can also benefit from the dual counter option—mechanical or digital—ensuring that both line tension and payout length are captured with accuracy.
Built to withstand temperature extremes ranging from –30 °F to 140 °F (–35 °C to +60 °C), the MHD-47 Wireline Measuring Head is tested and proven for dependable use in oilfield conditions worldwide.
