History

Barksdale Inc. was founded in the United States as a manufacturer of pressure switches for the oil and gas industry. The company expanded its product line to include level switches and temperature switches and grew into an international supplier of switching components. After integration into the Duriron Group and later Parker Hannifin, the brand remained active as Barksdale GmbH in Germany.

Frequently Asked Questions

What switch pressure range do Barksdale pressure switches have?
Barksdale supplies pressure switches for ranges from -1 bar (vacuum) to 700 bar. The switch pressure range is adjustable within the range of the model. Select the model with the range that encompasses your working pressure.
Are Barksdale switches ATEX-certified?
Yes, the Barksdale series D1S, D2T, and UDS are ATEX II 2G certified for zone 1 applications with Ex d (explosion-proof) housing. For zone 2, simpler models with Ex nA protection are available.
What is the adjustment function of a Barksdale switch?
Barksdale pressure switches are adjustable via an external set screw or internal adjustment knob. The adjustment range is typically 50-80% of the total range. Check the hysteresis (dead band) when setting.
Can I use a Barksdale pressure switch for steam?
Yes, Barksdale supplies pressure switches in stainless steel with high-temperature seals for use with steam up to 200°C. When ordering, specify that the application is steam for the correct material specification.
Are Barksdale pressure switches interchangeable with other brands?
Barksdale switches follow standard process connections (G1/4, G1/2, NPT) and in many cases are interchangeable with switches from other manufacturers. Check switch pressure, hysteresis, and electrical contact rating.
