Multi-Point Level Controllers
Multi-pont level controllers, like continuous controllers, monitor level along the length of a probe. Rather than transmitting a continuous signal, they may be calibrated to activate relays at various switch points along the length of the probe. The Princo L2720 and L2740 models may be programmed for as many as 4 independent switch points, or for 2 independent switch points and one zone. Zone operation may be in either pump up mode or pump down mode, All independent points may be set for fail-safe high or fail-safe low. |
