Posted by:

Real-time perception data that enables safe and reliable operation for autonomous driving and advanced vehicle safety at highway speeds.

IDC can test powerful sensors that deliver the range, accuracy and resolution needed for advanced autonomous vehicles.

The unit is a small compact LiDAR that is optimized for usage across a variety of applications, including automotive, mapping, robotics, security and so many more applications…it needs testing and IDC has the application knowledge.

LiDAR: The Use of Light Detection and Ranging Technology

Posted by:

LiDAR, short for light detection and ranging, is a remote sensing technology that uses light in the form of a pulsed laser to measure ranges (distances) to a target. A LiDAR sensor fires off beams of laser light and then measures how long it takes for the light to return to the sensor.

                Unsurpassed leak testing speed

At InterTech Dev Co. we strive to be world-class in testing this lighting technology and with that role comes the responsibility to be uniquely familiar with newer applications and to help our partners understand the true value in them e.g. Autonomous vehicles use LiDAR for obstacle detection and avoidance to navigate safely through environments, using rotating laser beams.

Our Testing expertise includes  testing LiDAR parts:

• M1075-01y Low Pressure Mass Flow Leak Detector.
• Audit Fixturing for quality control on LiDAR Test Parts.

The Challenge

• Smart Phones
• Medical Wearables & disposables
• Cameras for AV applications
• Radar/Lidar Enclosures
• And more…

These and similar electronics-based products can only be reliable if and when they are able to withstand dirt and water. Specifically, these electronics-based components must all meet or exceed IP67 ingress ratings.

That means they must be totally protected against dust and protected against the ingress of water in a harmful quantity after immersion in 1 meter of water for up to 30 minutes. Without proper IP 67 testing of sealed enclosure integrity, the lifespan and performance of a fast growing array of consumer and industrial electronics components cannot be assured.

InterTech M1075 – for unsurpassed leak testing speed and accuracy - using Mass Flow, Pressure Decay & Differential Pressure Testing

The Solution

An InterTech M1075 leak detector is used for fast and accurate testing to meet IP67 requirements. InterTech test technology automatically compensates for external changes such as temperature, and a unique test-centric design assures gage accuracy.

Mass flow leak testing with the InterTech M1075 is non-destructive, clean and easily handles specifications of 0.5 sccm at pressure of 0.2 to 0.3 bar with fast test times. Because it effectively checks for gross leaks prior to fine leak testing absolute reliability is ensured.

For example, a battery enclosure and valve are leak tested for IP 67 compliance at a rate of 120 parts per hour. In another application, Electronic Control Modules are tested in a two-step process – first for gross leakage, followed by a fine leakage test to 0.6 sccm limit and 10% Gage R&R.

LiDAR, short for light detection and ranging – a remote sensing technology that uses light in the form of a pulsed laser to measure ranges (distances) to a target.

Technology is also known as LIDAR, LiDAR, and LADAR.

IDC Testing expertise includes:

• M1075-01y Low Pressure Mass Flow Leak Detector.
• Manually operated audit fixture for quality control on LiDAR Test Part.

Autonomous vehicles use LiDAR for obstacle detection and avoidance to navigate safely through environments, using rotating laser beams.

Non-destructive fast IP67 leak testing

Posted by:

It is often confusing for an engineer to know what type of rating they need to look for when they desire to have a “waterproof” enclosure as there is a big difference between waterproof, water resistant, and other descriptive but not specific labels / requirements.

The Ingress Protections (IP) rating system is published by the International Electrotechnical Commission (IEC).

Users of InterTech’s test instrumentation get the competitive advantages of streamlined leak testing for various user product types with quickest response times, fast recovery from gross leaks (transducer saturation), testing that is independent of variations in supply pressure, and constant cycling from ambient pressure to test pressure, among other benefits.

How can soft super-flexible medical products be leak tested accurately and quickly?

Posted by:

It’s a given that manufacturers of medical devices and products are more than ever called upon to find new ways to help support homecare ; advanced wound care products that create negative pressure environments to accelerate healing are good examples.

These innovative specialty dressings deliver a vacuum at the wound site that helps draw wound edges together and in doing so removing infectious materials, reducing edema and promoting the type of tissue growth that closes the wound.

M1075 Leak Test Instrumentation

To function properly, these dressings need to conform to the wound bed and maintain negative (vacuum) pressures.
How to test these products is a big ask in a manufacturing environment given the production and quality requirements required.
