Technical Features
- Moisture content sensor for comparative measurement of moisture in wood materials
- Two hanger bolts are screwed into the wood surface and connected via measuring lines to the measuring electronics in the damp-proof sensor housing.
- The sensor housing with the integrated temperature sensor is also fixed in position on the wood surface. Plug-in ALMEMO® connecting cable.
- This device is designed for stationary installation and long term monitoring e.g. of wooden parts of buildings, roof structures (with laminated beams).
- Data logger operation in sleep mode (intermittent mode) is required in order to protect the wood from salinization or drying out.
- The material‘s moisture content is measured indirectly by determining its electrical conductivity, which is moisture dependent.
- It is also temperature-dependent. However, the displayed moisture value is automatically temperature-compensated by means of an integrated temperature sensor.
- The ALMEMO® device acquires the material’s moisture content based on the linearization curve stored in the ALMEMO® plug.
- This measuring operation can be performed using any current ALMEMO® device (version 6 and above).
