ELEMENT Controller Selection Considerations


By reviewing the features of each ELEMENT unit in the table below, the proper device can be easily identiifed based on the parameters desired. When selecting a unit, please keep in mind not only the functionality required for the current application, but also performance features that might be needed in the future. Table 1. illustrates the three ELEMENT controllers intended for on/off control & position indication (open/close). Table 2. provides an overview for the four ELEMENT controllers that provide valve positioning and, in the case of the Type 8693, PID process control. Use the tables below to select the most appropriate ELEMENT controller.

These are general recommendations, PAW BioScience & Burkert do not assume any liability whatsoever arriving from the use or mis-use of ELEMENT products. The user assumes all risks and responsibility.
