Point Level Controllers
Point level controllers, also referred to as switches, are commonly used as high or low level alarms for virtually any process material. Princo point level controllers all work by activating two sets of type C dry relay contacts which may be set for fail-safe high of fail-safe low action. Typically, conductive materials will be "tip-sensitive", whereas non-conductive materials - powders, oils, hydrocarbons, etc. - will need to be calibrated for a switch point several inches from the tip of the probe. |
