BARKSDALE FEATURED PRODUCT

ELECTRONIC DIFFERENTIAL PRESSURE SWITCH

BDS3000 is an electronic differential pressure switch was built for filtration systems applications with differential pressure ranges that vary up to 500 psid and with a maximum common pressure of 2,500 psi.

Transmitter functionality is offered via supplying analogue output signals 0 to 10V DC and 4 to 20mA, and is field selectable if needed. The full scale output can be adjusted to as low as 25% of FSO during installation enabling more flexibility, reducing the need to stock multiple pressure ranges.

BDS3000 with IO-Link combines Barksdale’s core strength of technical product expertise and customization capabilities with the forward looking communication protocol of IO-Link, supporting Industry 4.0, one of the key visions in the global industrial market.
