Each tong torque system consists of a tension load cell that converts line pull into a hydraulic pressure signal, which it sends to a pressure-sensing gauge through an interconnecting Hydraulic Hose. Each system also includes mounting hardware. Features: 1) Systems designed and build for the rugged requirements of the oil filled 2) Load Cell's are designed to ensure a long service life with minimum maintenance 3) 6"Fluid filled gauge has years of proven reliability and ease of maintenance 4) Target pointer on gauge helps operator maintain accurate torque We are also a proud member of the China Pressure Gauge Association.With many years experience,our company specialized in the YK series of Mud Pump Pressure gauges and other oilfield related instruments. we have a strong network that allows us the ability to design and customize.
