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.
