Variohm EuroSensor is part of the USA-based World Magnetics family of products (e.g. the trusted Dietz and Design Flex brands) and represent the company  exclusively in the UK and Europe. Offering quality aerospace pressure switches,  Variohm EuroSensor Value Engineered Products (VEP) designs and manufactures aerospace-class pressure, vacuum and differential pressure switches. These are ideal for air and compatible fluids.   Many in this industrial sector view VEP’s products as being characterised by their exceptional precision, durability, reliability and long working life. Component durability and longevity are necessary in view of today’s shrinking defence budgets and increasing modernisation and MRO contracts.

With five product series designs covering low, mid-range and high-pressure switching from 0.01 to 3,000 PSI, VEP’s extensive list of field-proven application areas include:
– air speed and airflow detection,
– landing gear and brake safety systems,
– rudder control assist and
– other demanding precision pressure switching tasks where accuracy, stability and repeatability are primary requirements.

Developed for harsh aerospace environments, each of VEP’s five product series cover pressure, vacuum or differential switching with wide flexibility in mechanical and electrical options.

For example, VEP’s 490 series has field adjustable pressure ranges from 3.0 to 3,000 PSI in a lightweight gold-plated aluminium housing with a dual-spring and stainless steel piston design that maximises accuracy and stability, allowing high proof pressure to 4500 PSI.

Designed to meet FAA’s 15-minute flame test requirement, the 490 has an altitude range from -1000 to 50,000 feet and, like all other product series available, offers SPDT switching at 5 Amps-resistive from a 30 V DC supply.

Other VEP models cover low-pressure and medium-pressure switching – the 654 series covers a 0.1 to 6 PSI setpoint range whilst the 648 series range is 40 to 500 PSI. High temperature versions, shock, and vibration resistant models, aluminium and optional stainless-steel housings and a selection of seal materials fulfil durability requirements throughout the complete range. As well as field adjustable set-points, factory-set and tamper-proof models are available. SPDT and DPDT switching and comprehensive pressure port and electrical interfacing options ensure that applications are fully met without compromise, although a custom design service is also offered.

From its UK and German sales office locations, Variohm EuroSensor provides complete technical support across VEP’s comprehensive product range. Product datasheets are available for download on the Variohm website. As a designer and manufacturer of its own range of sensors as well as a distribution partner for several other leading sensor component suppliers.

Variohm EuroSensor provides complete sales and application support across its comprehensive range of sensor technologies for position, force, pressure, load, and temperature measurement in industry, construction, agriculture, motorsports, research and more.
