Through the precise water content measurement with the robust humimeter BLO You can use the online evaluation device to optimally control your boiler and dryer, so that the efficiency of the system is significantly improved and costly errors are avoided.

Applications

For the determination of water content of wood chips and other materials with external sensors.

• Material-specific external sensors (wood chips & universal)
• Can be used flexibly depending on the requirements of the system
• Ready calibrated system
• Easy to mount
• Analog output for water content & temperature 4-20mA
• Lifetime Support

Range

The Humimeter BLO is equipped with two different external sensors depending on the requirements of the material or the system:

• The wood chip sensor is ideally suited for installation in screw conveyors, feed channels or bunkers. A wood chip sensor with a compression structure was specially developed for installation in places with low contact pressure and is suitable for light, loose wood chips.
• The universal moisture sensor offers an exact measurement for over 30 types of material, such as wood chips, pellets, sawdust, etc.

By separating the sensor part and measuring system, the sensor can be installed in an area that is difficult to access. That Humimeter BLO The measuring system can also be used in a very high temperature range (up to 70°C). It can be easily integrated into existing systems. Specially adapted sensors are available for different installation requirements. The optional PC software, in connection with the Ethernet interface, enables the storage, evaluation and export of the measurement data.

The following requirements are met

• Measuring device based on the requirements of the VDI standard 4206 sheet 4
• Material characteristics in accordance with EN ISO 16559 requirements
• Measuring device adjusted after calibration to the reference method EN ISO 18134-2

Please order the appropriate sensor separately.

Benefits

• Ready calibrated system (standard sensor)
• Material-specific sensors
• Up to 32 material types can be selected and expanded in the respective national language
• Additional display of the measured material temperature
• 2 analogue outputs 4 – 20 mA for water content and temperature
• Optional: 2 relay outputs for water content
• Optional: PCL interface including software
• Increase in efficiency of your boiler by up to 5%

Handling and measurement process

The water content and temperature are shown on an illuminated LCL display on the evaluation unit of the humimeter BLO Online system for moisture measurement. The connection to a control system is optionally possible via 4-20mA analog output with RS232, RS485, relay and other digital bus systems.

Since the online system has already been calibrated, it can be put into operation without great effort.
