Barksdale BLS3000 Electronic Dual Level Switch

Barksdale's BLS3000 Electronic Dual Level Switches combine three discrete components (dual level switch, pressure transducer, and digital level gauge) into one compact package. The BPS300 is available in three configurations:  1) dual switch points, 2) dual switch points with analog output (4-20 mA or 0-10 V), or 3) single switch with analog output.  Setpoints and deadband are easily adjusted using a user-friendly menu where hysteresis can be set up to 125% of its measuring range. Analog transducer outputs are scalable from 25% to 100% of the full adjustable range. The BLS3000 offers an easy to read 4-digit 14-segment LED angled display which is rotatable to 320°.  The BLS3000 is an ideal solution for applications requiring precision level control, flexibility and extremely long life.General Specifications*Sensor element:Reed switchMaterials:Wetted parts:    Stem (Fitting, Tube):    Float:    Seals:    Electronic housing:Stainless steel 316TiNBR (BUNA-N) foamFKM, EPDM or NBR (BUNA-N)Stainless steel 316Ti, PBT, elastomerOperating elements:3 easy-response push-buttonsEnclosure rating:Type 1 / Type 4X (IP65) / Type 6 (IP67)Protection class:IIIElectrical connection:Plug M12 x 1, 4-pin / 5-pin / 8-pin (depending on Output selection)Process connection:See Product Configurator for process connection optionsFloat BN17:Density medium:Depth of immersion:min. 0.02 lb/in³ (0.60 g/cm³)0.59” ± 0.07” (15 ± 2 mm) (water)0.74” ± 0.07” (19 ± 2 mm) (oil 0.75)Ø0.70”, height 0.98” (Ø17.8 mm, height 25 mm)Dimensions enclosure:1.6 Ø x 4.5 inches (41 x 110 mm)For 1/2" NPT (without M12 connector or probe).Contact factory for other sizes.Weight:Approx. 0.77 lb (350 g) (for G1/2” size and 250 mm L0, for exact weight, contact factory)Total lenght (L0):9.8" (250 mm), 14.6" (370 mm), 16.1" (410 mm), others on request up to 39.4” (1000 mm)Accuracy:± 1 digit (without turbulence) including temperature influence and repeatabilityResolution:1/5" (5 mm)Max. pressure:43.5 psi (3 bar)Temperature range:Medium:Ambient/Operating:Storage:-13 °F to +176 °F (-25 °C... +80 °C)-4 °F to +158 °F (-20 °C… + 70 °C)-22 °F to +176 °F (-30 °C… + 80 °C)Power supply:15 to 28 V DC,reversed polarity protected (SELV, PELV)Power consumption:Approx. 50 mA (without load)Approx. 80 mA (Output Code 6)Digital display:4-digit 14-segment LED display, red, digit height 0.35 inches (9 mm)Error display:LED RED and alphanumeric displayAnalog output:Current output:Load:Scanning rate:Voltage output:Rating:Adjustment range:4-20 mAmax.
