LN-P Carlson Piezometer is designed for revealing the water pressure inside the hydraulic constructions or rocks. At the same time, it also can measure the temperature of the installed point.
Robust construction
Provide long-term reliability and stability
Suitable for MCU and remote monitoring

LN-J Carlson Jointmeter

more

LN-J Carlson Jointmeter is designed to measure movement and the opening or closing of peripheral joint in concrete face rockfill dam. It also can be used to measure movement with rock and concrete masses or at rock-concrete interfaces. The gage can be adapted for measuring the bedrock deformation by modification. At the same time, it can measure the temperature of the installed point.

LN-R Carlson Rebar Strain Meter

more

LN-R Carlson Rebar Strain Meter is intended to monitor the stress or reinforcing steel or the anchor bar in the concrete or other constructions. It can also measure the temperature of the setting place. Robust construction
Long-term reliability and stability
Provide multiple standard products with different over water pressure types

LN-S Carlson Strain Meter

more

LN-S Carlson Strain Gauge is designed for direct embedment in dams and concrete structures or attached to a surface with mounts to reveal internal deformations. The main purpose of the strain meter is to indirectly determine stress. It can also measure the temperature of the installing place Robust construction
Long-term reliability and stability
Provide multiple standard products with different over water pressure types

LN-AC Carlson Load Cell

more

LN-AC Load Cell consists of a cylinder of high-strength alloy steel with multiple carlson strain gages located symmetrically around the circumference of the cell . It is used to measure the load of the anchorage cable, the rock anchorage bar, the anchorage pin and the vaulted backet, or other heave load for a long time. It can also measure the temperature of the setting place.
