Level Control Relays & Conductive Probes
|
|
Rhomberg level control relays are primarily used in conjunction with conductive level probes (refer to Rhomberg CP-3C level probes) for controlling the level of a liquid between a high and a low level, for filling or draining applications. These units normally control pumps. (Available in 11-pin plug-in or DIN rail format)
