Ultrasonic Sensor – ToughSonic REMOTE 30

Ultrasonic liquid level sensor ToughSonic remote 30

 Maximum Range 30 feet (9.1 Meters)

The ToughSonic REMOTE 30 is a remote liquid level sensor with a maximum measurement range of 30 feet (9.1 meters).  This digital sensor is designed for accuracy and long-termultrasonic sensor stainless steel housing durability in remote monitoring applications.  With a stainless steel housing, full epoxy potting and NEMA-6P and IP68 ratings, it operates in the harshest climates.  It comes equipped with Senix Lightening Guard, a system that protects both power and communications circuits from repeated electrical transients of up to 7 kilovolts. The ToughSonic REMOTE 30 uses up to 20% less energy than the ToughSonic 30. It is fully configurable using SenixVIEW software.  This sensor is mounted on bridges, piers and tanks all over the world in critical remote level monitoring applications.
