BDS3000 now with IO-Link option! 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.

The large 14 segment LED angled display is aesthetically pleasing and allows clear readability of the process pressure from multiple viewing angles. Mounting holes are built-in, making it easier to install in various orientations to fit your system needs. Even if the unit must be mounted upside down, the internal software is capable of rotating its display 180°. Plus, the 320° rotatable electrical connection and display housing makes installing the unit very simple, helping reduce installation costs allowing for versatility of installation method and location. Robust EMI protection allows for stable output in today’s factories where EMF and high powered walkie-talkies and VFD’s are present. Additionally, the IP67 class rated housing makes this unit suitable for the wettest of environments, and even full submersion.

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.
