Long range ultraSonic sensors.

P43 ultrasonic sensors from PIL, measure distances. Applications include object recognition for agriculture and fluid levels, distance measuring for trucks and loading ramps, level sensing in dusty conditions, parking lot detection/barrier monitoring as well as a variety of other industrial and manufacturing applications.

These ultrasonic sensors provides the industry’s greatest 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.

“The new PIL P43 Ultrasonic sensors are an excellent solution for a variety of applications where highly accurate distance sensing is critical,” explains Dr. Heimann, CEO of PIL.  “We are very excited to provide the industry with the first long range Ultrasonic sensor that can provide accurate results at a distance of up to 6000 mm.”

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.

A variety of PIL ultrasonic sensors were previously introduced to the US market and were known under different names and brands. An up to date cross-reference list can be found at the website of their partner H+K Inc.
