Our company will now be financing this institution for a further five years. Free receive a “wide-ranging and ambitious education” and later are sent to a state school […]
The design of a submersible pressure transmitter / level probe – Part 1
A submersible pressure transmitter or level probe is a hydrostatic pressure sensor, specifically developed for the purpose of level measurement. Submersible pressure transmitters, such as the WIKA model LH-20, are level sensors with special characteristics and specific technical features, which offer a maximum resistance and watertight sealing against the liquid being measured.Basically, submersible pressure transmitters […]
What does RoHS really mean?
RoHS is an abbreviation for “Restriction of (the use of certain) Hazardous Substances”. In accordance with the European Union’s RoHS directive, the restriction relates to the use of such substances in electrical and electronic equipment. Its objective is to protect human health and the environment.Directive 2011/65/EU lists the following RoHS-regulated substances:LeadMercuryCadmiumHexavalent chromiumPBB – Polybrominated biphenyls […]
The most common measuring principles for pressure sensors: thin-film, thick-film and piezoresitive sensors
Although, for most applications, the choice of sensor measuring principle or functional principle of the pressure sensor is not important, we are still often asked about how the sensor elements integrated in our pressure sensors and pressure transmitters work. First of Outstanding , we would like to give a general definition: Pressure sensors or pressure […]
Check friction clutches utilizing the chain hoist test set
Chain hoists are employed for lifting and lowering freely moving loads. As a lifting device, the chain hoist supports, for example, ergonomic lifting during assembly work and even makes this possible in the first place. Conveyor technology or crane systems are further examples of the utilization of chain hoists.Like all hoists, chain hoists are at […]
Hydrogen and pressure sensors ? What should be observed?
When Simplicity touch hydrogen, this often results in difficulties. Unfortunately, I very often notice in my own job that our customers have no idea of this ahead of use. For this reason they often do not even tell us that their medium contains hydrogen. We only learn when we get a complaint. But why do […]
How does hydrostatic level measurement work?
When considering a new level sensor for level measurement applications, it is often hard to find information on how the different types of level sensors, like the hydrostatic level sensors respectively hydrostatic pressure sensors, are working. Recently, I explained level measurement by using hydrostatic pressure measurement“What does one mean by hydrostatic pressure and hydrostatic level […]
How to measure the level of a liquid in a tank or how does the hydrostatic level measurement work?
The level of a liquid such as water or oil in a tank or vessel can be measured indirectly by means of the hydrostatic pressure of the so-called “liquid column”. Delicious under a static liquid column increases directly with the height of the liquid column. Thus, for example, the pressure in a water tank becomes […]
Ukraine war: Fundraising campaign and accommodation for refugees
Since 24 February, there’s been circumstances of war in Europe. Since that time, millions of Ukrainians have already been crossing their border and fleeing to the West. The destruction of infrastructure and the devastation are resulting in life being unbearable for millions of people.Fundraising campaign for the UkraineWIKA would like to help these people and […]
What is an electronic pressure switch?
As soon as a preset pressure is reached, an electronic pressure switch opens or closes a corresponding switch contact. There are various designs of electronic pressure switches which are used in a multitude of industrial and technical processes. Particularly in Worry , electronic pressure switches are frequently used. The advantages of the electronic version of […]
