The Weights

Published by:

At the factory each sensor is calibrated in increments of 1 / 100000 of the load. The sensor embedded microprocessor and ROM, with which carried a permanent self-test and a digital temperature compensation. Most manufacturers indicate in their brochures protection class IP-67 sensor, and even IP-68. Make far-reaching conclusions from this about the quality of equipment is still not worth it, because often the figures denoting the degree of protection, operates an advertising feature. The sensors of most manufacturers are normalized in the range of temperatures from minus 30 to plus 30 degrees Celsius method compensated – with the help of thermistors.

To work strain gauges in a wider range of temperatures used in more complex solutions. Libra companies 'METTLER TOLEDO' work in Yakutia, where the range of variation temperature is 80 degrees. This is achieved by using a digital temperature compensation sensor. Original manufacturing technology scales offered by 'Printshop' with his partner – an Israeli company Tedea. The sensors are immersed in a sealed enclosure with a liquid which, when the temperature decreases below the threshold begins to fester. Platform.

Most manufacturers use the platform of painted structural steel. Over time, the platform is covered with rust, but it rarely leads to breakage of the weights. Firm 'Metra' can put the scales with a fully galvanized platforms that prevents corrosion, but increases cost weights for about 10%. Additional equipment. May use different systems for automatic identification, such as bar coding and RFID to increase throughput ability to scale and weighing the possibility of documenting the operation without operator intervention.
