1.      Tính năng kỹ thuật:

-          Diagnostic feedback provided to the master device: bottle number, sample number, response code/message, sampler battery voltage

-          The installation of a bottle position encoder enables verification of arm position before sampling and then moving the arm if it is not centered above the correct bottle

-          Multiple bottle configurations possible: 1, 2, 3, 4, 6, 8, 12, 24

-          Auto deploy that automatically sets the purge and vacuum times based on hose length

-          Repeatable volume collection via metering chamber

-          Selectable internal or external power via three-way power switch

-          One control cable for all control types

-          An optional water present sensor detects the presence of water at the mouth of the sampler intake hose to ensure a sample is available

• Large pump: 0 to 40°C
• Standard pump: 0 to 50°C

-          Operating voltage: nominal 12 Vdc; maximum 16 Vdc; minimum 10.8 Vdc

Controller:

-          Sampler triggering methods:

• SDI-12 Master Device
• Modbus RTU Master
• Campbell Scientific PakBus® datalogger
• Pulse trigger (1 to 10,000 pulses)
• Time-based sampling (stand alone)

-          RS-485 communication: Can return sampler status when triggering samples via pulse or time-based control

-          Backup power source: Internal lithium battery to maintain program settings and information in case of power failure

-          Bottle position encoder: Verifies arm position and moves to correct bottle if it is out of position

-          Multi-purpose button: Service sampler, collect manual sample, and auto deploy

-          Auto deploy: Automatically sets the purge and vacuum times based on hose length (between 25 to 100 ft)

-          Sampler status/feedback (available after every sample): Bottle number, sample number, response code, sampler battery voltage

Vacuum System:

-          Pinch Valve: Fixed – normally open

-          Purge Cycle: Adjustable from 1 to 800 s; 280 s for SDI-12

-          Suction Cycle: Variable (until liquid contacts level electrode in metering chamber or adjusts automatically to two times the purge time)

-          Metering Chamber Cover: Nylon (standard); Teflon (option)

-          Volume Control Tube: 316 stainless steel

-          Metering Chamber Level Electrode: 316 stainless steel

-          Intake Hose: Ordered as a common accessory. Campbell Scientific offers PVC hose with 25 ft and user-specified lengths. Intake end can have a lead sinker or stainless-steel strainer. Sampler end can have a clamp or quick connect termination.

-          Discharge Hose Material: Latex (standard); options include Teflon lined, silicon

Horizontal Velocity:

-          Refer to the "PVS5120 Intake Velocity versus Hose Length at Sea Level" plot in the Related Documents section.
