May 13, 2015 - PIL releases P43 long range ultrasonic sensors with a range up to 6000 millimeters—nearly 10 ft.
Applications include object recognition for fluid levels, distance measuring for trucks and loading ramps, level sensing in dusty conditions, barrier monitoring as well as a variety of other industrial and manufacturing applications.
The P43 ultrasonic sensors provide a range from 250 mm to up to 6000 mm. M12, M18 and M30 dimensions are available - with or without thread or cubic housing. Highly accurate, it provides a small sound cone shape, two integrated internal LED’s for echo justification, and analog internal sensors – no need for digital translation and no loss of accuracy. The P43 provides a standard analog 0-10V / 4-20mA output and two switching outputs. In addition to these fixed settings, the P43 series can be programmed via Teach-In for various other custom settings.
Ultrasonic sensors use an ultrasonic transducer to send and receive sound waves. Specially coded ultrasonic signals are transmitted in a set pattern. After being reflected from the object to be measured, the signals are received by the sensor and decoded. The recorded time of flight is temperature compensated and converted to distance data. Ultrasonic distance sensors are often used in harsh, industrial environments because they are independent of the material and the color of the object to be measured and are not affected by light, dust and fog.
They function very precisely and linearly with background suppression.
