Built in alarm indicator Liquid Level Switches
from Arjay Engineering
Reliable level alarm and control of liquids and solids. As a liquid or solid rises or lowers around the probe, the capacitance field changes. This is monitored and used to control the two on-board relays. Each relay includes full differential control to allow the relay to activate and de-activate... [See More]

from ABB Measurement & Analytics
The resonant frequency is continuously monitored for changes created by a wet or dry sensor and an alarm is provided via relay. The RS85 should be used when the application requires optional process connections, exotic materials of construction, coatings, finishes or adjustable time delay and... [See More]

from Time Mark Corporation
The Model 409 is a compact, socket-mount device for level control of conductive liquids. The internal relay is energized when operating power is applied. When the liquid level reaches the probe, the relay de-energizes. When the level drops below the probe, the relay will reset. A fixed, two-second... [See More]
