A single unit for the measurement of flow, pH, temperature and conductivity
19 April 2011
Burkert’s type 8619 multiCELL transmitter/controller is designed to cut processing costs in water treatment and hygienic processing applications, providing one device for the direct connection of a wide range of sensors to measure parameters such as flow rate, pH, ORP, temperature and conductivity.
The multiCELL multichannel transmitter/controller fits a standard ¼ DIN cutout to provide an IP65 fascia. This versatile analysis measuring system is suited to use in a wide range of applications including water treatment, foodstuffs and pharmaceuticals. It comprises a fully-featured basic modular unit equipped with a large backlit display, softkey controls, two digital and frequency inputs, direct connections for various sensor types and two digital and analogue outputs that drive solenoid valves, control valves and actuators, such as dosing pumps.
The functionality included in the basic unit can be expanded through the addition of hardware and software modules. Depending on signal requirements, up to six pre-configured I/O boards can be added, and software packages can be installed for further enhancements of the transmitter functions. In addition, the multiCELL can also be configured as a multipoint data logger with data storage on SD cards.
The advantage of this modular expansion facility is that multiCELL users pay only for the features that they actually require. Moreover, since the multiCELL provides a single transmitter across a wide range of applications, inventory and training costs are both minimised.
The multi-channel multiCELL is suited to use in a range of applications in ‘water treatment’. These include: cooling towers; drinking water monitoring; the production and monitoring of ultra pure water; verifying the water quality in desalination processes of reverse osmosis plants, using pH, conductivity and flow sensors and in bio reactors, where pH, ORP and temperature measurements and control are requested.
In the area of hygienic processing, it can be used for CIP applications that require direct connection of pH, ORP and temperature sensors, as well as analogue outputs for process monitoring. In this, and in all applications for which the multiCELL is designed, the built-in menu navigation remains transparent, intuitive and tolerant to operators’ mistakes despite the substantial functionality of the device – with values only accepted after following a confirmation input.
