Ultrasonic sensors have a range up to 6,000mm

PIL announces the availability of its new P43 ultrasonic sensors to measure distances. 

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

The PIL P43 ultrasonic sensors provides the industry’s greatest range  – from 250mm to up to 6,000mm. 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 LEDs for echo justification, and analog internal sensors – no need for digital translation and no loss of accuracy.

The P43 provides a standard analogue 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 colour 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.
