Not the same: temperature range and temperature limit
Temperature range and temperature limit for pressure sensors ? will there be a difference? My intuitive answer would be: Yes! The initial term describes a section and the second its border. On second glance, however, I must conclude that both words ultimately express the same thing in relation to temperatures: Range and limit are defined […]
Worldwide use of Ex instruments and Ex pressure sensors due to international IECEx approval
Pressure sensors and electronic devices may only be used in hazardous areas if they have been tested and approved by a recognised authority in terms of their explosion protection features. So far, ไดอะแฟรม was mostly carried out by a national institution which, after successful testing, issued a national declaration of conformity.Having to obtain a national […]
Electronic pressure sensor/pressure transmitter or mechanical pressure indicator?
For some years now, it has been possible to increasingly automate production processes, and by doing to to achieve substantial cost reductions in some cases. This raises the question: does it still make sense to use mechanical pressure measuring instruments?The answer to this question is obvious and simple: yes. Both electronic pressure sensors and mechanical […]
Pressure monitoring in the pharmaceutical industry with a universal instrument
Pressure monitoring in the pharmaceutical industry is a demanding task with a wide variety of requirements. However, a corresponding diversification in instrumentation does not have to be an inevitable consequence. This is demonstrated by the use of a universal process transmitter from WIKA in the production of API (“active pharmaceutical ingredients”).Such active pharmaceutical ingredients form […]
Angular connector form A leaking/ loss of IP ingress protection
What are the rules that must be observed when assembling the angular connector EN 175301-803 A, to ensure that the IP rating is maintained, that is, connector and device remain really leak-tight? Unfortunately, a lot of things can go wrong when using the angular connector EN 175301-803 A (better known as valve connector, big DIN, […]
What is the dissipation loss for a pressure transmitter?
The term ?dissipation loss? can be found in the data sheet for a pressure sensor or pressure transmitter. One needs this specification to become able to protect the pressure sensor from overheating.If a pressure sensor is operated in a hot environment, it can be necessary to limit its electrical energy. If one neglects this aspect, […]
Selection criteria for pressure gauges: type of pressure
Within the selection criteria for pressure gauge s, type of pressure takes top priority. The measurement of gauge pressure, in fact, reliably fulfils the purpose with the majority of processes. However, for diaphragm seal in industry, pressure gauges for absolute or differential pressure come into consideration. This article presents the differences between the three types […]
Investments in India strengthen market position
With investments in India, WIKA has strengthened its position on the subcontinent. However, their purpose is not solely from the regional market ? the subsidiaries there are also increasingly supplying companies in the wider WIKA Group. diaphragm seal in GhaziabadIn Ghaziabad near New Delhi, WIKA has generated a state-of-the-art and highly efficient production facility (photo […]
Natural gas: On-site calibration optimised at the metering skid
On-site calibration of measuring instruments is frequently very time-consuming and expensive. This is also true for applications with several measurands. One of these of this may be the metering skid, something for the custody transfer measurement of the amount of natural gas transferred. A global player in the industry from Saudi Arabia has now significantly […]
The challenges of installing pressure sensors on air compressors
Pressure measurement is an integral part of the monitoring process that measures how economically an air compressor is running at all times. diaphragm seal rising cost of energy means that each unit within a factory must always be running at optimal performance, and for air compressors that means increasing or decreasing the compressor load to […]
