Mode of operation

a0011584

Sampling steps with a peristaltic pump

Sampling takes place in three steps:

1. Purge/rinse

The peristaltic pump runs in reverse and forces liquid back to the sampling point.

2. Intake

The peristaltic pump runs forward and draws in liquid. Once the liquid detection system detects the

sample, the pump is controlled by the flow and the specified sample volume is calculated automatically.

3. Purge

The pump runs in reverse again and forces the liquid back to the sampling point.

One advantage this system offers for obtaining a representative sample is the possibility of rinsing the suction

line several times:

Liquid is initially drawn in until the liquid detection system reacts, then the pump switches and forces the liquid

back to the sampling point. This process can be repeated a maximum of three times. The sample is then taken

as described.

The pump rollers deform the tubing, thereby causing a negative pressure and the suction effect.

The liquid detection system is based on a pressure sensor which detects the difference between a pipe that is

filled and not filled.

Thanks to a patented process for automatically detecting the suction height, the user does not have to enter

the suction height or suction line length. The self-calibrating software guarantees that the sample volume

remains constant.

a. Flow curve

b. Time proportional sampling:

Constant time constant volume (CTCV)

A constant sampling volume is taken at steady intervals.

c. Flow proportional sampling:

Variable time constant volume (VTCV)

A constant sampling volume is taken at variable intervals.

d. Flow proportional sampling/time override:

Constant time variable volume (CTVV)

A variable sampling volume is taken at steady intervals.

e. Event-controlled sampling:

Sampling is triggered by an event.

Single and multiple samples can also be grouped in a program in

addition to the sampling methods listed. Furthermore, the software

allows interval sampling, switchover and event functions. The latter

permit up to 24 subprograms to be active simultaneously for a

variety of applications.

A sampling table makes it possible for users to program the bottle

assignment, time interval and sample volume.

Signals for external control can be connected via analog input and

binary input in the standard version of the product. Customized

text is entered to ensure the correct assignment of the inputs in the

memory.

Sample distribution CSF22 offers a range of bottle combinations and distribution versions. The sequencial version can be changed

or replaced easily without the need for special tools. In addition, the software makes it possible to configure

individual bottles and bottle groups as well as assign them to change based on a programmed event.

Note!

The composite version can not be upgraded to sequencial.

Bottle groups and distribution version depending on the order version:

Sample preservation The sample bottles are located in the sample compartment made of stainless steel.

All parts that transport liquid can be removed and cleaned easily without the need for additional tools.
