商品説明

The LVCN700 Series has been discontinued. Please see the LVCN210 Series as a possible alternative or contact our Flow Engineering department.

The LVCN700 Series general purpose ultrasonic switch provides non-contact level detection from up to 8 m (26') away, and has 3 relay outputs. Each relay can be configured on a single setpoint alarm, 2 latched setpoints for automatic fill or empty including lead-lag, or 2 independent setpoints for out-of-bounds alarms. In addition, relays 1 and 2 can be interlocked for relay alternation or duplex operation. The switch is well suited for a broad range of corrosive, waste and slurry-type media, and is broadly selected for atmospheric day tank, pump lift station and waste sump applications.
