SENTRY Isolok SAB is a pneumatic automatic sampler that takes representative samples at a fixed volume and repeatably from pressurized or unpressurized pipelines. The piston-type sampler takes product from the line into a fixed-volume space (annulus) and discharges it. It is used on lines carrying thick liquids and slurries such as bauxite mud and resin bead slurry.

A typical SAB configuration includes a 25 cc sample volume, 316 stainless steel body, nickel tungsten carbide bushing, polyurethane piston seals and flanged hub connection. It is installed with a pneumatic air set (4-way 24 VDC solenoid, filter, regulator, gauge) and an SBC PLC controller.

Isolok SAB features

  • 316 stainless steel body; bore lining nickel tungsten carbide bushing
  • 25 cc fixed sample volume (annulus); piston outer seal polyurethane
  • Discharge outlet 1" male NPT; 70 mm vented bottle adapter
  • Air set: 4-way 24 VDC solenoid, filter, regulator, gauge
  • SBC PLC-based controller: NEMA 4X, 230 VAC / 50 Hz, CE marked
  • Sealing gaskets, O-rings and piston sets as spare parts
