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.
