The WIKA programme covers the following product lines for various fields of application.
WIKA product lines
Electronic pressure measurementWIKA offers a complete range of electronic pressure measuring instruments: pressure sensors, pressure switches, pressure transmitters and process transmitters for the measurement of gauge, absolute and differential pressure. Our pressure measuring instruments are available in the measuring ranges 0 ... 0.6 mbar to 0 ... 15,000 bar. These instruments come supplied with standardised current or voltage output signals (also intrinsically safe per ATEX or with flameproof enclosure), interfaces and protocols for various field buses. Whether ceramic thick film, metal thin film or piezoresistive, WIKA is the leading manufacturer worldwide that develops and produces the full range of today’s leading sensor technologies.
Mechatronic pressure measurementAs a result of the almost unlimited options for different combinations of mechanical and electrical connections, an extraordinary range of instrument variants is possible. Various digital and analogue output signals are also available for these measuring instruments.For our measuring instruments we use latest sensors, tested in automotive applications millions of times over. They work without any kind of mechanical contact, consequently they are wear-resistant, and there's absolutely no influence on the mechanics.
Mechanical pressure measurementIndicating pressure gauges for over-, absolute and differential pressure with Bourdon tube, diaphragm or capsule pressure elements have been proven millions of times over. These instruments cover scale ranges from 0 … 0.5 mbar to 0 … 7,000 bar and indication accuracies of up to 0.1 %.
Diaphragm sealsWIKA diaphragm seals, mounted with pressure gauges, pressure transducers, pressure transmitters etc., are recognised and valued internationally for the most difficult of measuring tasks. The measuring instruments can thus be used at extreme temperatures (-130 ... +400 °C), and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media. The optimal diaphragm seal designs, materials and filling media are available for each application.
Electrical temperature measurementOur range of products includes thermocouples, resistance thermometers (also with on-site display), temperature switches as well as analogue and digital temperature transmitters for all industrial applications. Measuring ranges from -200 ... +1,700 °C are covered.
Mechatronic temperature measurementAs a result of the integration of switch contacts and output signals into our mechanical temperature measuring instruments, we can offer a wide variety of combined instruments. With switch con-tacts the pointer position triggers a change-over. Electrical output signals are realised via an additional, independent sensor circuit (resistance thermometer or thermocouple).
Mechanical temperature measurementThe mechanical temperature measuring instruments work on the bimetal, expansion or gas actuation principle and cover scale ranges from -200 … +700 °C. All thermometers are suited for operation in a thermowell if necessary.
Level measurementWIKA has a comprehensive range of level measuring instruments available for temperatures up to 450 °C, densities from 400 kg/m³ and pressure ranges up to 500 bar. This includes standard instruments and customised products.
Flow measurementOur portfolio for primary flow elements includes orifice plates, meter runs, flow nozzles, Venturi tubes, pitot tubes and restriction orifices. With our extensive product range we are in a position to cover almost all industrial applications. Customised solutions can be developed to meet your specific needs.
Calibration technologyWIKA offers a broad product range of calibration instruments for the physical units of measurement for pressure and temperature, and for electrical measurands. A multitude of specific patents ensure unmatched performance characteristics with many of our calibration instruments. The range of services comprises the calibration of pressure and temperature measuring instruments in our accredited DKD/DAkkS calibration laboratories and a mobile service to calibrate your instruments on site.

Bypass level indicators
How does the bypass level indicator work?In a communicating bypass chamber mounted to the side of a vessel a float moves with the level of the medium to be measured.The magnetic field of the radial-symmetric magnetic system activates the magnetic display attached to the outside of the bypass chamber as well as the switching and measuring elements.
Sight glass level indicators
How does the sight glass level indicator work? ■ Direct level indication without power supply ■ Transparent sight glass level indicator ■ Reflex sight glass level indicator ■ Refraction principle with mica shields
Magnetostrictive level sensors
How does magnetostrictive level measurement work?These level sensors are used as measured value pick-ups for the continuous recording of liquid levels, and are based on determining the position of a magnetic float according to the magnetostrictive principle.The measuring process is triggered by a current impulse. This current produces a circular magnetic field along a wire made of magnetostrictive material which is held under tension inside the probe tube. At the point being measured (liquid level) there is a float with permanent magnets acting as a position transducer. The superposition of these two magnetic fields triggers a mechanical wave in the wire. This is converted into an electrical signal at the end of the wire in the sensor housing by a piezoceramic pick-up. The measured propagation delay enables the origination point of the mechanical wave, and thus the float position, to be determined with high accuracy.
Level sensors with reed chain
How does level measurement with reed chain technology work?These level sensors work on the float principle with magnetic transmission.The float's magnetic system in the guide tube actuates a resistance measuring chain that corresponds to a 3-wire potentiometer circuit.The measurement voltage generated by this is proportional to the fill level and finely stepped as a result of the contact separation of the measuring chain and is thus virtually continuous. Resolutions between 3 and 18 mm are available depending on the requirements.

Optoelectronic switches
How does the optoelectronic switch work?The optoelectronic switch contains an infrared LED and a light receiver within a glass prism. The light from this LED is directed into the glass prism which forms the tip of the sensor. So long as the tip does not come into contact with the liquid to be measured, the light is reflected within the prism to the receiver. When the liquid rises within the vessel and surrounds the tip, the light beam is refracted by the prism in the liquid, so that the receiver is no longer or only weakly reached by the light. The switch then outputs this change as a modified switching signal
Hydrostatic level sensors
How does hydrostatic level measurement work?Hydrostatic level sensors are a special type of pressure sensor used for level measurements in tanks, wells, shafts and bore holes. Special low-pressure sensors enable the level to be measured by a side attachment at the tank. In deep shafts and wells, a submersible pressure transmitter (also called level probe) in IP68 version is immersed directly in the medium and positioned as close as possible to the bottom. Both as side attachment and immersed application, the hydrostatic pressure sensor measures the hydrostatic pressure of the liquid column above it and is directly proportional to the filling height. The hydrostatic pressure depeding on the gravitational constant and medium density thus enables a direct conclusion regarding the changing level, i.e. the height of the liquid column above it.
Guided wave radar
How does guided wave radar technology work?The model LSD-4 sends microwave pulses from the sensor element to the surface of the liquid in the tank.When the surface of the liquid is reached, the electromagnetic waves are reflected back to the sensor. The time interval that the wave requires from leaving the sensor element till it returns is directly proportional to the level.If the microwave is coupled to a rod/cable probe and not radiating freely, then one generally talks about the 'guided microwave' or 'guided wave radar' method of measurement.
Float switches
How does the magnetic float switch work?A float with a built-in magnetic system moves, with the level of the medium to be measured, on a guide tube which has one or more reed contacts built into it. The magnet actuates the contacts at the pre-set switching heights and thus allows individual levels to be monitored. The simple and proven operation principle is suitable for a very wide range of applications.It works independently of foaming, conductivity, dielectric, pressure, vacuum, temperature, vapours, condensation, bubble formation, boiling effects and vibrations.
