Hydraulic Load Cell
Model 4500-RT-HYDLO FEATURES
• Rugged construction • Compact size • Easy to install and read • Direct load measure-

ment with pressure gauge drift— suitable for long-term measurements quired able transducer. This optional feature suits situations where access to the cell is difficult. The HYDLO can accommodate small inclinations in loading. Larger misalignments should be compensated with the use of spherical seats.

• Negli gible

• No maintenance re-

Description
The Roctest model HYDLO consists of a sealed cell composed of two plates welded together around the periphery, and filled with de-aired oil. The cell is directly connected to a pressure gauge. The load applied to the cell induces an oil pressure variation, which is sensed by the gauge. The compact size of the HYDLO eases installation and allows for quick and simple readings. Two configurations of HYDLO are available. To monitor a tensile load, a hollow centre cell enables the passage of an anchor through the cell. To monitor a compressive load, a solid centre cell is used. With both of these configurations, remote pressure reading is available by connecting the cell with flexible tubing to a remote vibrating wire, electrical 420 mA, or hydraulic pressure

• Remote reading avail• Not affected by eccentric loading

APPLICATIONS
The HYDLO Hydraulic Load Cell is designed for direct measurement of loads in tiebacks, foundation anchors, rockbolts, struts or tunnel supports.
