Selection parameters as per Application of Ultrasonic Sensors

Slides:- 

This tutorial is About basic Selection parameters to consider while selecting any Ultrasonic Sensor. 

Not Specific to any type ( Like Level, fork etc )

Above are Basic Common Quick Point consideration while selection of any Ultrasonic Sensor.

 

PNP output is the Signal Which Give ( + V) Output to PLC or Controller.

NPN Output is the Signal Which Give ( -  or 0 V) to PLC or Controller.

Sensor Selection must be done in Basis of PLC or Controller Input, if PLC or Controller require PNP input Signal than PNP output Sensor must be selected and Vice versa.

We must Know the Response time of Sensor required before Selection. Means,

If we have ultrasonic Senor operating at 400Hz that Means.

response time = ((1/400)/2)= 1.25ms. 

1.25 ms can also be said as total processing time sensor required to generate Result.

Means if any object is passing in front of ultrasonic Sensor, and time gap between two objects must be greater that this response time i.e 1.25ms.

otherwise Sensor would not be able to detect object.

Communication - IO Link Communication is used between Sensor , actuators & Controllers. usually th operating range is 20m.

HART Protocol is a wireless communication Protocol.

Protection class - IP and NEMA rating is Mostly Used protection class.

IP rating is mostly used in Europe and Asia. While NEMA rating is used in US.
