Fields of application for pressure sensors 3 – Absolute pressure sensors: why is it necessary to use absolute pressure sensors or pressure transmitters
Electronic pressure sensors usually measure the change in pressure through the deformation of a diaphragm. If this diaphragm is exposed to the process pressure on one side and “vented” on the other side (and thus exposed to the ambient pressure), the deformation is reduced (because it is counterbalanced) by exactly this ambient pressure. Therefore, the […]
What do dead bands mean with a float switch?
Float switches with reed contacts enable both reliable and economical level measurement. Accordingly, digital pressure gauge are used in a wide variety of applications. As with all level sensors using the float principle, users must pay attention to the dead bands when configuring the float switches. What is this design-related variable all about?A float switch, […]
WIKA Poland?s calling ? and each is coming
WIKA Poland can look back on 100 years of company history. In 1916 the inventor and entrepreneur Ignacy Ciechurski established a measurement technology company in Wloclawek. Because the staff has played an excellent role in the business?s success, the subsidiary wanted to thank them for their commitment and organized a grand family picnic. More than […]
What does maximum operating pressure or working pressure mean with pressure sensors?
Our customers like to talk about a maximum operating pressure or working pressure. Unfortunately, these two terms are not defined for pressure sensors, which means that a definitive answer cannot be given. All we can assume is that, by maximum operating pressure or working pressure, the maximum pressure that can occur under normal operating/working conditions […]
Switch with ?CCC Ex? for the Chinese market
CCC ? without proof of China Compulsory Certification, many industrial goods are denied access to the ?Middle Kingdom?. Since 1st October 2020, this compulsory marking in addition has extended to products with explosion protection. Therefore, เกจวัดแรงดัน that fall under the provisions have the corresponding certificate ? ?CCC Ex?. This includes switches such as mechanical pressure […]
Hiking against dementia
Dementia is one of the main causes of disability in later life, with over 850,000 people currently diagnosed with the disease in the UK. A team of twelve from WIKA UK took part in a 25-kilometre march organised by the Alzheimer’s Society with the motto “United we trek against dementia”.Starting in Richmond, Surrey, the trek […]
Traceability
Measuring instruments for pressure and temperature are employed in almost all regions of industrial manufacturing. Due to continuous mechanical, chemical and thermal loading, these instruments age and will therefore not guarantee the correctness of the measured values over the course of time. Through timely calibration, however, the alteration of the measured value could be determined.Along […]
Obamania in front of the WIKA booth
The United States was the partner country of the HANNOVER MESSE 2016. For pressure gauge octa , a president of the United States inaugurated the world’s largest industrial fair. Elke Knobling (Marketing Services), organiser of WIKA’s participations in fairs, describes the impact which Barack Obama’s visit had on the WIKA booth:Shortly before the trade fair […]
SIL-certified: Functional safety with mechanical switches
Mechanical pressure and temperature switches perform sensitive tasks in safety-relevant applications, e.g. monitoring limit values. Their functional safety must be guaranteed accordingly. That is always the case if the instruments fulfil the requirements of the corresponding safety integrity level (SIL) in accordance with the IEC 61508 standard. WIKA switches have been issued SIL approval because […]
What advantages does a cable box have for submersible pressure sensors?
A cable box for submersible pressure sensors for level detection is an inconspicuous and simple accessory. With its help, the installation costs for certain measuring locations can be significantly reduced.Submersible pressure sensors measure the hydrostatic pressure of a liquid, from which the level in a vessel or open container is calculated. The pressure sensors, therefore, […]
