Engineering Heritage of WIKA Alexander Wiegand (German Metrology Standards Since 1946)

The German industrial instrumentation group WIKA Alexander Wiegand SE & Co. KG was founded in 1946 by engineer Alexander Wiegand and Philipp Kachel in Klingenberg am Main (Bavaria, Germany).

Over more than 78 years of continuous engineering innovation, the family-owned enterprise has grown into a global market leader in pressure, temperature, level, flow, and force measurement as well as reference calibration technology.

Today, more than 11200 employees across 43 operating subsidiaries deliver over 50 million quality instruments annually, while the worldwide installed base of active WIKA instrumentation exceeds 500 million units.

The flagship manufacturing and R&D headquarters in Klingenberg alongside production plants in Germany, Switzerland, the USA, and Asia operate under certified ISO 9001 quality management, ISO 14001 environmental standards, and ISO 50001 energy management systems.

In-house accredited DKD/DAkkS calibration laboratories guarantee metrological traceability to national standards, while instruments carry ATEX and IECEx hazardous-area approvals, SIL2 and SIL3 functional safety ratings per IEC 61508, and 3-A and EHEDG hygienic certifications.

Design Advantages of 232.50 Bourdon Gauges, 432.50 Diaphragm Gauges, and 990 Seals

Flagship mechanical Bourdon tube pressure gauges series 232.50 and 233.50 per EN 837-1 are constructed entirely of corrosion-resistant 316L austenitic stainless steel with laser-welded measuring cells and process sockets.

Covering scale ranges from 0.6 to 1600 bar in 63, 100, and 160 mm nominal dial sizes with accuracy classes 0.6 and 1.0, these instruments resist acidic vapors and sour gas hydrogen sulfide environments.

In Solidfront safety versions 232.30 and 233.30 per EN 837-1 S3, a solid welded steel baffle wall separates the sensing tube from the dial face while the blow-out back releases pressure rearward upon tube rupture.

For ultra-low pressure measurements down to 2.5 mbar, differential pressure monitoring up to 100 bar, and service with crystallizing or viscous media, WIKA manufactures capsule gauges 632.50, diaphragm gauges 432.50 and PG43SA, and differential gauges 732.51 and DPGS40.

In severe chemical processes with media temperatures up to +400 deg C and pressures up to 600 bar, instruments are vacuum-fitted with diaphragm seals series 990.27, 990.34, and 990.22 featuring diaphragms in Hastelloy C276, Monel 400, titanium, tantalum, or PTFE linings.

Electronic Pressure Sensors A-10, S-20, Process Transmitters IPT-20, and PSD-4 Switches

Across industrial factory automation and process plants, WIKA electronic pressure transmitters series A-10 and S-20, intrinsically safe transmitters IS-3, and intelligent process transmitters IPT-20 and CPT-20 cover measuring ranges from 0.05 to 4000 bar.

Depending on the target pressure span, instruments utilize thin-film polysilicon strain sensors on stainless diaphragms, piezoresistive cells, or capacitive ceramic elements achieving reference accuracy down to 0.05%.

Standardized 4-20 mA, 0-10 V analog outputs and digital HART 7, Profibus PA, and Foundation Fieldbus protocols ensure seamless integration into DCS and PLC systems.

For local digital indication and discrete circuit switching on hydraulic power packs, pumps, and machine tools, electronic pressure switches PSD-4 and PSD-4-ECO cover ranges from -1 to 1000 bar with a bright 14-segment LED display, dual-axis rotation of 335 and 300 degrees, PNP/NPN transistor

outputs, and IO-Link 1.1 communication. In refinery safety shutdown loops, plants rely on PGS23 switchGAUGE instruments with 831 inductive contacts and rugged explosion-proof mechanical switches PCA, PCS, and PXS rated up to 600 bar.
