Q & A
BLS2000 Electronic Dual Level Switch with Brass Tube Q & A
+ What is the Barksdale Electronic Dual Level Switch with Brass?
The Electronic Dual Level Switch (Brass) is a level sensing instrument that uses an electronic sensing principle and a brass tube/fitting design. It can detect two discrete levels (switch points) and provides analog output.
+ What density of media can it measure?
It is capable of reliably measuring media with density less than 0.6 g/cm³.
+ What are the available resolutions and lengths?
Resolutions of 8 mm or 12 mm are available. The total length (L0) can range from 250 mm to 3000 mm (custom lengths also possible).
+ How many switch points does it support?
It supports a maximum of two switch points (i.e. two independently configurable levels)
+ What analog outputs are supported?
Two analog output options are available: 4–20 mA or 0–10 V
