Moisture measuring instruments - Import export

The key to the successful optimisation of compressed-air systems is data. The METPOINT® range of measurement equipment with sensor technology and monitoring provides the data base for the evaluation and assurance of the compressed-air quality and for the identification of hidden cost drivers. Our measurement equipment can also be employed for the extension of plants and for the early elimination of malfunctions. With our sensor technology, you can capture residual oil content, residual humidity, volume flow and pressure – constantly, faultlessly and with exemplary precision. Our Monitoring and Data Logging makes all the relevant data accessible to you and your employees at a glance, ensuring the safety of your processes and the quality of your products. In this way you can take your energy management and quality control requirements to the next level of success.

The traversable straddle gauges are used for offline measurement. They are placed onto the roll and moved manually, thereby measuring the form of the rolls from crown edge to crown edge. They are characterised by a high measurement point density of 1 mm and a high repetition accuracy of ± 2 µm. With the evaluation software optimised over decades together with our customers for this application, curves can be pivoted and superimposed, centered and smoothed. The scope of supply also includes a panel PC.

The gauges from the VSL Series measure the form, diameter, roundness and eccentricity of the rolls during the grinding process with very high precision. Form, radial run-out and eccentricity are measures with a precision of ± 1 µm. If an interface is available, they communicate online with the controller of the roll grinding machine and thus enable even more cost-effective use of the grinding machine. With the appropriate configuration, they measure the height and lateral alignment of the roll in the grinding machine before grinding, often enabling the set-up time to be significantly reduced. Vollmer produces the automatic roll measuring gauges for both bench-mounted machines where the roll is moved along the grinding wheel and for support machines where the grinding wheel is moved along the rotating roll. Vollmer supplies the systems for a broad spectrum of roll diameters.

The AQUATRAC Station is a residual moisture meter that can be used both in the laboratory and in production without qualified personnel. The measurement is chemical-free and water-selective by means of capacitive dew point determination. The device is browser-based, so that complete access to all functions is possible via Chrome, IE, Firefox, etc. via network, smartphone, tablet or PC. A freely configurable material database and user-based user database with rights assignment that can be configured in small steps make working with the station simple. A Precisa scale can be coupled via USB to transfer the sample weight, and an optional label printer and signal light are available. Variable, freely combinable abort criteria for a measurement are the measuring time, the gradient H2O/min and a maximum moisture content. This makes the instrument flexible, highly precise and easy to operate both in production and in the laboratory.

The AQUATRAC-V is a residual moisture meter that can be used in the laboratory as well as in production without qualified personnel. The Measurement is reliable, water-selective and safe using a reagent the calcium hydride. The water released from the sample reacts with the calcium hydride to form hydrogen, which is measured by increasing the pressure in the system and gives a measure of the water content of the sample. This measuring principle is listed in ISO 15512:2019, "Plastics - Determination of water content" as method e.). The same standard also contains the Karl-Fischer measuring principle. The measuring instrument has a robust construction and is designed for use without qualified personnel in production and laboratory. This makes the AQUATRAC-V the world's only standard-compliant water-selective measuring instrument for use in production.
