商品説明

OMEGA’s LVCN1700 ultrasonic level sensor provides level detection up to 8 m (26.2') with 3 programmable relays for level switch or level control functions, and is configured via the integral pushbutton display module. Each relay can be configured on a single set-point (high level alarm or low level alarm) or latched on two set points for automatic fill or empty in simplex (one pump or valve), duplex (two pumps) or triplex (three pumps) level control modes with selectable time delay and fail-safe logic. The embedded level controller can lower cost by replacing external control hardware. This non-contact liquid level sensor is ideally suited for corrosive, sticky or dirty liquids, and is broadly selected for pump lift station, sump and day tank level applications
