Instruments for pressure measurement by WIKA
The manufacture of measuring instruments for pressure measurement has a long tradition with WIKA. We have now been producing mechanical pressure gauges for over 60 years. Today we are recognised in the market as leaders worldwide in the fields of temperature measurement, pressure measurement and calibration technology. Worldwide, approximately 600 million WIKA measuring instruments are in use.
WIKA offers a wide portfolio of instruments for pressure measurement:
How does electronic pressure measurement work?
In electronic pressure measurement, the pressure is measured by a sensor which receives the pressure to be measured, or the change in pressure, and converts it into an electrical signal. The electrical signal is then a measure of the magnitude of the applied pressure or the pressure change. WIKA offers you measuring instruments with all the sensors you would normally expect in the electronic pressure measurement market: Metal thin-film and piezoresistive. WIKA develops and manufactures these themselves.
How does mechatronic pressure measurement work?
For system control and monitoring using mechatronic pressure measurement, mechanical measuring instruments are combined with electrical output signals and/or switch contacts. The electrical output signal enables modern electronic measured value registration. Electrical circuits can be opened and closed using switch contacts. Thus, plants cannot only be monitored, but also directly controlled as set measured value limits are crossed. Mechanical pressure switches complete the WIKA portfolio.
How does mechanical pressure measurement work?
In mechanical pressure measurement, measuring instruments are used with pressure elements that deform elastically under the influence of a pressure which is positive or negative in relation to atmospheric pressure (ambient pressure). In contrast to measuring instruments using electronic pressure measurement technology, they do not require any power supply for operation. Alongside their simple operation, their advantage lies in their marked robustness. WIKA offers you mechanical pressure measuring instruments with scale ranges from 0 ... 0.5 mbar up to 0 ... 7,000 bar (0 ... 0.007 psi up to 0 ... 101,526.4 psi)

Why must the differential pressure in model 7 differential pressure gauges with bourdon tubes not be allowed to be less than 1/6 of the full scale value?
For model 7 differential pressure gauges, the static pressure is the same as the full scale value over 270 degrees of rotation. With an expected differential pressure of 15 psi (1 bar) at a static pressure of 145 psi (10 bar), the two hands would o ...

What is the difference between a standard pressure gauge and a safety pattern version?
A safety version (code S3 per EN 837) has an additional solid baffle wall welded between the dial and the measuring system. In addition, the case has a back wall that can blow out completely. The window is typically made of laminated safety glass. ...
