Specification of pH Controller

Description

Widely used in plating, wastewater treatment, water treatment and swimming pools, the BL7916 provides convenient installation, ease of use and maximum reliability.

  • Easy Installation: Designed with mounting holes built into the base and front-facing controls and pump assemblies
  • Proportional Dosing: Slows the stroke rate as the measured value approaches the user selected point, avoiding overdosage
  • Rugged Construction: Rugged, fiber-reinforced polypropylene IP55 rated casing; parts with chemical contact made of PVDF, FPM/FKM and PTFE
  • Isolated Recorder Output: To enhance troubleshooting and the ability to record data while monitoring the application
  • Simple Pump Action: A positive displacement solenoid with few moving parts with no rotating parts, gears or cams to drastically reduce mechanical failures
  • Auxiliary Dosing Contacts: Allows the user to attach a mixer or priming pump that is activated only when the pump is dosing

Chemical Dosing Pump Specifications:

  • Alarm Relay Set Point: 1 isolated, 2A, max. 240V, resistive load, 1,000,000 strokes
  • Dosing Control: proportional, acid or base, user selectable
  • Analog Ouput Signal: 4-20 mA (isolated)
  • Dosing Terminals: 1 isolated, 2A, max. 240V, resistive load, 1,000,000 strokes
  • Over Current Protection: 250V fuse
