Ultrasonic Sensor – ToughSonic REMOTE 50

ultrasonic liquid level sensor ToughSonic remote 50

Maximum Range 50 feet (15.2 Meters)

The ToughSonic REMOTE 50 is a remote liquid level sensor with a maximum range of 50 feet (15.2 meters). This digital sensor is designed for accuracyUltrasonic sensor stainless steel housing and long-term durability in remote monitoring applications. With a stainless steel housing, full epoxy potting and IP68 rating, it operates in the harshest climates. It comes equipped with Senix Lightning Guard, a system that protects both power and communications circuits from repeated electrical transients of up to 7 kilovolts.  The ToughSonic REMOTE 50 uses up to 20% less energy than the ToughSonic 50. It is fully configurable with SenixVIEW software. This sensor is mounted on bridges, piers and tanks all over the world in mission-critical remote level monitoring applications.
