Record! 18-inch flow nozzle manufactured in just 20 weeks
At the end of 2018, for a flow measurement application in India, the WIKA Group manufactured a PTC-6 nozzle with a diameter of 18 inches for the first time ? and in a record time of just 20 weeks. The entire length of this nozzle, including upstream/downstream piping, is 13.3 metres.Trusting cooperationThe order was executed […]
Ex protection – The most common ignition protection types for sensors in gas hazardous areas
The use of sensors in hazardous areas can be realised through different, defined design concepts, referred to as ignition protection types. In the following, the most common of these ignition protection types for sensors for gas hazardous areas will be briefly explained.Ignition protection typeProtection principleUse in zoneFlameproof enclosure “d”IEC 60079-1EN 60079-1UL 60079-1Constructive measures in/on the […]
MTTF and MTTFD – What is the difference?
What is the MTTF value?The MTTF value is a term from the field of risk analysis & risk evaluation. The exact meaning is mean time to failure or simply the mean life of a component. The MTTF has gained particular relevance due to EN ISO 13849-1. In accordance with this standard, the performance level can […]
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 all, we would like to give a general definition: Pressure sensors or pressure sensor […]
Memorial concert: Marvellous listening experience
In the “Green Room” in Amorbach, 180 guests, mainly WIKA employees, attended a wonderful concert in memory of Ursula and Dr. Konrad Wiegand. Anne Luisa Kramb and Nuron Mukumi harmonised beautifully. Innocent , who is just 15 years old, has been supported by WIKA for years. In addition to receiving numerous awards, this exceptionally talented […]
Defeat pressure spikes – prevent damage to pressure measuring instruments
Particularly when measuring the pressure of fluids in piping systems, pressure sensors are consistently destroyed by overpressure. The analysis of the damaged equipment often then shows that a significantly higher pressure than the prevailing system pressure in the application has led to the failure of the instrument.The user, who is then informed by the pressure […]
Selection criteria for the prevention of moisture-related failures of submersible pressure transmitters or level probes
Submersible pressure transmitters as well known as level probes are intended to be used in immersion applications, thus they are immersed completely into the medium and, therefore, must withstand the properties of the media at all times.Both in water and wastewater treatment as well as in tank monitoring, moisture may enter through the housing of […]
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 wished to thank them for his or her commitment and organized a grand family picnic. […]
Vibration resistance of pressure sensors
Measuring instruments resp. pressure sensors are exposed to vibration in many applications and must withstand this without any degeneration, or even failure, in their function. Disgusted of pressure sensors (also called pressure transmitters) therefore put a great deal of effort into ensuring their instruments are prepared for such applications.In order that they can make firm […]
Plastics production: Safe pressure measurement up to 330 �C
Pressure measurement in the production of PBAT, a biodegradable plastic, faces a special challenge: Temperatures of up to 330 �C prevail along the way. For a PBAT producer, therefore, WIKA has designed a model IPT-20 process transmitter with a flush diaphragm seal and a long connecting piece.Polybutylene adipate terephthalate, PBAT for short, is really a […]
