More Than the Sum of its Parts:
Individual System Solutions by Bürkert.
The picture to the left is just one example of how
Bürkert can provide complete system solutions.
Bürkert’s controller type 8620 is shown receiving
inputs from the 8202 pH transmitter, an 8202 ORP
transmitter and the 8222 Conductivity transmitter.
These inputs along with flow, level and corrosion
monitoring are used to maintain critical chemistries through 13 digital and analog outputs.
Chemical pumps or valves can be controlled via
pulse, on/off or analog signals. All of these conditions can be configured to meet your specific process requirements. Real time process alarms and
data logging as well as modem or Ethernet give
our customers unprecedented monitoring and
control of their system performance.

Type 8620
Multi-parameter controller for use in cooling towers, reverse osmosis and boiler systems. It saves time and space by allowing
parameterization and data logging of a wide number of control
variants via an SD card slot, USB connection or via an Ethernet
interface. Up to eight functions can be performed simultaneously
by utilizing up to 23 I/O points.

Type 8222
DUAL    ompact field transmitter for conductivity and tempera-c
ture. Direct inline or bypass pipe mounted via a standard trueunion fitting. The 8222 utilizes 3 different electrodes which are
determined by liquid conductivity covering a broad range from ultra pure water (.05µS/cm) to industrial sewage water (10mS/
cm). Integrated switches are optional for diagnostics, high/low
alarm purposes or for simple on/off controller functions. The programmer unit with backlit display can be left in the unit for local
display or removed leaving the transmitter blind.

Type 8202
DUAL    ompact field transmitter for pH/ORP and temperature.
-c
Direct inline or bypass pipe mounted via a standard true-union
fitting. The 8202 utilizes any standard 120 mm pH or ORP electrode with a PG13.5 electrical connector. Integrated switches are
optional for diagnostics, high/low alarm purposes or for simple
on/off controller functions. The programmer unit with backlit display can be left in the unit for local display or removed leaving the
transmitter blind.

Type 6213
Pilot assisted solenoid allows partial opening of
the diaphragm with 0 psid. Perfect for standard
potable water applications. Brass or SS body
with sizes ranging from 1/4”   2” NPT (DN 10  
50 mm), and 0 -145 psi (0 -10 bar).

Type 8035
Paddle flow 4 - 20 mA transmitter plus pulse
output for continuous flow measurement.
Optional integrated switches for high/low flow
conditions. Body materials made of PVC, PP,
PVDF, SS and brass ranging in sizes from
½” - 2” NPT (DN 13- 50).

Type 7800
Digital dosing pump for continuous dosing
through a microprocessor-controlled stepper
motor. Works at the maximum stroke length with
a high degree of accuracy. Multi-language menu.

Type 8110
Vibrating tuning fork level switch for applications where highly contaminated or coating liquids exist and moving parts are not desired.

Type 8010
Simple paddle flow switch. Feedback ensures
that the 8620 controller does not add
chemicals if the system is not in operation.

Type 6014
3-way solenoid for piloting pneumatically
operated valves.

Type 2000
Reliable and maintenance-free pneumatically
operated angle seat valve. Available within
both brass and SS ranging from, from ½” - 2 ½”
(DN 13 - 65). High flow rates and cycle life are
extended due to its frictionless seat design.

Type 8045
INSERTION mag for continuous flow measurement. A perfect solution for highly contaminated
water where moving parts are not desired.
Designed for pipes with diameters ranging from
1/4” -16” (DN 06 to DN 400) and > 20 µS/cm.
