By pressure indicator, we mean an instrument for the measurement of pressure in gases and liquids. Here, we differentiate between mechanical (pressure gauges), electronic and mechatronic pressure indicators. WIKA has over 60 years experience in the manufacture of pressure indicators. Benefit from our know-how and find the right pressure indicator for your measuring requirement:

Electronic pressure indicator

The basis for an electronic pressure indicator is formed by the pressure sensor. It converts the measurement parameter of pressure into an electronic signal. The advantage of electronic pressure indicator lies in the excellent dynamic performance and the low material stress. This gives them a high load resistance and long-term stability. They are available in very small sizes.

WIKA develops and produces all leading sensor technologies: Ceramic thick film, metal thin film and piezoresistive.

Mechatronic pressure indicator

Electronic assemblies or components are integrated into a mechanical pressure indicator. The measured pressure is displayed locally, however, in addition, the pressure indicator offers an electrical signal or includes an electrical switching function. With these instruments, the measured value can also be read reliably on site if the power supply fails or the measuring signal is disrupted.

With the combination of mechanical pressure indicators with different signals and switches, this results in a comprehensive range of mechatronic pressure indicators. For our pressure indicators we use the latest sensor technologies, tested millions of times over in automotive applications. They work without any kind of mechanical contact, consequently they are wear-resistant, and there's absolutely no influence on the pressure indicator.

Mechanical pressure indicator

Because of their robustness and simple handling, indicating pressure indicators are widely used. Their elastic pressure elements deform under the influence of pressure. The measuring system is made from a capsule element, diaphragm element or Bourdon tube. The measuring systems are made from copper alloys, alloyed steels or, if required for specific measuring tasks, from special materials. WIKA manufactures mechanical pressure indicators with scale ranges from 0 … 0.007 psi up to 0 … 100,000 psi with indication accuracies of up to 0.1 %. For pressure measurement with high dynamic pressure loads or vibration, you will find mechanical pressure indicators with liquid filling in the WIKA portfolio. Through their damping, they are optimally protected against destruction.

Diaphragm seals

Even for the most demanding measuring requirements, you'll find the right solution with WIKA. Diaphragm seals enable pressure measurement with harsh conditions such as, for example, corrosive, highly viscous or fibrous media, very high temperatures, awkwardly placed measuring points, hygienic regulations or also toxic media or media harmful to the environment.
