The CWSL0040100 Contact Wireline Weight Indicator System is a hydraulic weight measurement system supplied with a load cell and 100 ft hydraulic hose. It is designed to provide a direct indication of wireline tension/load during wireline operations.
 
The system shown is configured for an 8.00 in indicator with a 4,000 lb / 100 ft hose setup, as identified on the supplied product image. Hydraulic wireline weight indicator systems commonly use a load cell to transmit hydraulic pressure to the indicator gauge, allowing the operator to monitor line tension without requiring an external power source.
