Schaller Humimeter Project Development Moisture and Temperature Measurements

Project development
Schaller moisture meters

It is important to know the humidity or moisture content of your products and furthermore control these parameters for plant or process optimisation. Omni Sensors and Transmitters together with Schaller Messtechnik can help you with this.

We will develop the best solution for your problem, produce the necessary components and integrate them in your present or planed process and plant.
We work in close collaboration with you by analysing your problem, development and start up, and supervise your running process or plant.

Thermometry

In many applications it is necessary to know temperature profiles and variation. Omni sensors and Transmitters together with Schaller can help you with a one-off special solution or a more complex monitoring and control system.

Analysis of different interior insulation systems.

The University of Technology in Graz is working on a project analysing different interior insulation systems. These systems are used when legal requirements don’t permit exterior insulation. As the dew point is located deep inside the brickwork, water condenses on the roof beams. Roof beams can become completely rotten due to the high moisture level and resulting fungal decay, this may lead to the total collapse of the roof. Materials under test were installed in 5 test areas in two rooms (one directly above another) The aim of this 3-year project is the analysis and development of connections between problematic construction elements such as roof beams, reveals, inserted ceilings and walls, as well as the product neutral evaluation of environmentally benign building materials. The entire measurement instrumentation for this purpose is provided by humimeter Schaller GmbH. Specially developed in-wall air humidity and temperature transmitters serve as sensors that stand out for their flat construction. In addition the moisture of the wooden beams is determined by humimeter BLW moisture meters, in order to rapidly detect any developing damp areas The complete sensor system converges to a control box, which is linked to a computer for data recording via diverse interfaces.

Temperature control of a pumpkin seed dryer

Schaller has developed a full automatic temperature monitoring system for a new pumpkin seed dryer with 10 drying chambers. Two temperatures are recorded within each chamber, the first is the temperature of the deepest layer of the product, the measurement device is integrated into the floor of the chamber. The second temperature is measured with an IR-probe slanted from above. An additional portable unit affixes within any chamber to generate a more detailed temperature profile.

For optimal process control a fluid flow probe, a temperature probe and an air moisture probe are installed to analyse incoming air. Data from all probes were analysed and visualised on a central SPS. The SPS connects via ethernet with a computer over a 100m distance. This computer collects and archives all data. It is possible to both control the process out of the office and analyse the data later to further optimise the drying process.
