Pressure sensor

Pressure sensors by WIKA

A pressure sensor converts the physical quantity 'pressure' into an industry-standard signal. It offers a standardised interface and frequently is also referred to as a pressure transmitter or process transmitter.

What different types of pressure sensor are available from WIKA?

You can have a WIKA pressure sensor in numerous variants: Around 176 measuring ranges are available from 25 mbar to 15,000 bar in the main international units, as gauge pressure, absolute pressure and vacuum, but also as +/- ranges. We have over 14 output signals in our portfolio, including a number of current and voltage signals, and RS-232 and bus signals. Different connectors and various cables can be selected from the 18 electrical connections. In a selection of 34 pressure connections, you'll be able to find internationally established thread types and also flush connections. Furthermore, an infinite number of options complete our broad spectrum of pressure sensors. Among these, you will find various accuracies, pressure-spike damping, designs for special media and special ambient conditions, and much more.

How does one select the right pressure sensor?

You can find the appropriate pressure sensor yourself from the categories below.

We are happy to advise you in your customer-specific selection and can examine individual solutions for you.

Which pressure sensors are suitable for industrial applications?

In the WIKA portfolio you will find a selection of pressure sensors for general industrial applications. These are available in numerous internationally established designs:

  • numerous gauge, absolute and vacuum measuring ranges
  • accuracies of up to 0.125 % BFSL
  • standard signals for current and voltage, e.g. 4 … 20 mA and 0 … 10 V
  • various plug and cable versions
  • all internationally established pressure connections

The model A-10 is the most-used pressure sensor in industrial applications. The S-20 premium pressure sensor has been designed for critical, high-level and harsh operating conditions. In high quantities, the O-10 offers the optimal solution.

WIKA pressure sensors with special features

Which pressure sensor is suitable for high pressure and which for low pressure?

With highly dynamic pressures to 15,000 bar, the model HP-2 is used, while the A-10 pressure sensor is suitable for the smallest of measuring ranges to 0 ... 50 mbar.

Which pressure sensors are suitable for the highest accuracy?

For the highest accuracy applications, the P-30 pressure sensor offers an accuracy of down to 0.05 % (full scale).

Which WIKA pressure sensors have digital output signals?

  • USB interface: Pressure sensor P-30
  • Switching output: Pressure switch PSD-4

Can pressure transmitters work without a power supply?

No. Because pressure transmitters communicate via digital bus signals, they require DC voltage. However, mechanical pressure switches do not require a power supply.

FAQ

How can I protect a liquid-filled gauge when the media’s temperature is above boiling (212°F/100°C)?

Use a pressure gauge siphon, diaphragm seal, or capillary line. These are all accessories that cool the media’s temperature before reaching the gauge, or separate the media from the instrument.
