Spray Sensor & Semiconductor

Spray Pattern Sensor

The Spray Pattern Measurement System is a first-of-its-kind large, high-speed sensor mat designed to visualize and characterize accumulated fluid deposition information for spray processes and is able to identify where a sprayed fluid or gas actually land.

The Spray Pattern Measurement System was designed for manufacturing, process engineers and researchers who are working with spray and/or coating processes involving very fine mists and who need to understand specific spray patterns as part of a manufacturing or coating process to control the quality of the finished product. 

Many spray process requirements are met only through “trial and error”, meaning numerous adjustments to achieve a desired result.  PPS’s Spray Pattern Measurement System addresses this problem by digitizing, visualizing, and quantifying fluid deposition patterns that enable real-time feedback and electronic records for comparison and analysis, providing new levels of insight into spray and coating processes.

Features:

• High resolution array sensor images the amount of fluid deposited over an area and provides instantaneous feedback for quick adjustments or analysis.  

• Ability to measure fluid deposition even for applications in which pressure is infinitesimal.

• Waterproofed Sensor Mat capable of providing valuable data under any spray process conditions. This data shortens development time and helps improve the quality and cost of products and processes.

• High performance capacitive sensing technology saves time and improves results by significantly reducing recalibration and repeated tests allowing developers to resolve problems and answer questions faster.

• High speed USB 2.0 interface provides latency-free results.

• Chameleon Visualization Software provides intuitive, easy to use, high-quality visualization and easy access to data for analysis and export to other applications.  

Automotive

Application

• Impact pressure testing of water sprayed when cars drive over puddles

Customer:

• Multinational automotive manufacturer

Challenge:

• Past solution used several single elements sensors placed in various locations and on engine components, making it difficult to determine the peak water pressure

• The sensor height (20mm) was disruptive to the water flow.

Solution:

• PPS Spray Pressure Sensor System

Benefits:

• Informs designers and engineers on the optimum location of water sensitive parts such as the radiator, suspension and exhaust tubes for successful long-term operation

• High resolution array where thousands of points could be measured

• PPS’ Spray Pressure Sensor was extremely thin and did not interfere with the experiment.

CONSUMER PRODUCTS

Application

• Capture moisture spray patterns for consumer hand sprayers

Customer:

• One of the largest consumer goods companies in the world

Challenge:

• Moisture pressures are so low that it is difficult to measure.

• In some situations, there simply isn’t enough pressure to measure, even when using a highly sensitive membrane-type sensor.

Solution:

• PPS Spray Pattern Sensor 

Benefits:

• Enables the assessment of spray distribution for the light mist emitted by hand sprayers.

• Quantify how much fluid is deposited on the sensor and in what pattern.

• Designers can quickly and efficiently improve product designs to achieve optimal results
