Interruptores de Nivel
Level switches Minimelder, Minimelder-R and Maximelder-R
Designed to signal minimum or maximum levels of water, heating oil EL, L, M, oil/water mixtures and neutral, non-viscous and nonadhesive liquids in tanks.
Mini-/Maximelder consists of a control unit and a height-adjustable float probe. The Minimelder probe is suspended in the lower part of the tank and generates an alarm signal when the liquid level drops below the probe. The Maximelder probe is mounted in the upper part of the tank and generates an alarm when the liquid reaches the probe. The switching level is adjustable. When these levels are reached, the units generate visual and audible alarms.
Minimelder Generates an alarm signal when the level falls below the minimum level. Cost-effective solution for building automation applications. System owners are alerted to a low fuel oil level in time. Minimelder-R Similar to Minimelder, but with a relay (normally open contact) for transmission of the signal to external alarms or for connection to telecommunication or building control systems. For professional applications.
Maximelder-R Generates an alarm when the level reaches the maximum set liquid level. In all other respects similar to Minimelder-R.
