For over 30 years we've been providing solutions for automotive manufacturing, factory automation, performance research & functional testing. We offer a diverse selection of sensors, as well as integrated solutions for focused applications.


Manufacturing Automation

Partners in Producing the Cars of Today 

The days are long gone when Quality is left to chance, your process is only as good as the measurements you take and the evaluations you make. For the last 25+ years A-Tech has been partnering with industry leading manufacturers and OEM's, helping in producing better cars with greater efficiency.

It was not so long ago when visual inspection was done with calipers and a human eye and part handing was done by a human with gloves. The demands on the modern manufacturing environment is constantly evolving and that means accuracy, precision & speed are in heavy demand. A-Tech constantly scours the globe for the best technologies, then applies them as solutions to meet the ever growing challenges.

Quality control is paramount & cycle time is key. In most cases, no two applications are exactly the same, and a low cost solution that gives you versatile, near instant evaluation & serialized data collection is a fundamental requirement.  

A-Tech has been involved in the wide range of activities that supports the Automotive and Specialty Vehicle industries. This includes Passenger Vehicles, Motorcycles, Electric Bicycles, Light and Heavy Duty Trucks, Buses, Construction Equipment, Timber Harvesting Equipment, Mining and Agricultural Machinery, Recreational Vehicles and Military Vehicles.

Along with a world class portfolio of sensors, amplifiers & process meters we have Integrated Solutions for:


 Compact, Rugged Nutrunners & Servo Presses with Integrated Control and Data Collection for modern manufacturing processes

The Servo Press Tool is a space-saving design and minimum mounting footprint that allows for multiple press operations, in close proximity to each other. Force ranges start at 2000 N ( 450 lbs) and go up to 200,000 N ( 45000 lbs) and tool strokes from 100 mm up to 400 mm. Special models for High Speed, Force Holding, Dimensional Gauging, ... are also available.

The diverse control capability can be optimized to reduce cycle time, improving productivity, improve your product quality, reduce the scrap assemblies, reduce the operating and Maintenance costs and reduce the impact on the environment.

The Servo Press Controller performs monitoring of operation counts, thermal loading and travel distances to maintain the Tool’s endurance. Alarm conditions insure operation within the designed performance criteria. This eliminates excessive force conditions, thermal stress, etc., providing the process with a high reliability, minimum down time and optimized cycle time.

The Electric Nut Runners feature an electromagnetic motor coupled to a planetary gear pack, then through a custom designed torque sensor. Virtually all electric motors have built in encoders, allowing them to control based on displacement and speed. They are available in Torque Ranges from 2 Nm up to 255 Nm.

Electrical Vehicles: High Voltage Components

Reliable Equipment for High Voltage Applications

Electrification is becoming increasingly prevalent in many different vehicle classes and types, and powertrain and vehicle component technology is developing enormously. This is particularly true of batteries, which continue to improve in terms of ­efficiency, size, charging time and capacity.

In order to increase vehicle performance, there is a clear trend toward higher voltages that can exceed 1000 V systems.

Electric and hybrid vehicle with high-voltage components can be tested for functionality, safety and reliability during development and the manufacturing process.

 

E-Mobility electrical measurement testing in the development, production and testing of high voltage components for the electrical vehicle (EV), as well as in onboard measurement, energy storage and the charging process.

  • HIL – Hardware in the Loop Simulation
  • EOL  – End-of-Line testing
  • Stress Screening

Many components have to be tested under load, thus highly dynamic processes. stress screening, etc. during development. The effects of voltage peaks due to abrupt load changes or coupling capacitances requires high voltages capability during testing in development, in-vehicle testing and production validation.

For these demanding testing tasks, Knick provides a comprehensive range of high-pre­cision isolation transducers for measuring currents and voltages in high-voltage circuits. In addition to the high-isolation the Knick devices offer high-speed and high-precision.

Knick brings these features and specifications to a wide-range of standard products, but also is capable of providing engineered custom solutions, specific to unique applications.

New Batteries and Battery Management Systems require extensive testing and validation , that includes investigations of charging and discharging cycles at different temperatures. These tests are carried out in specially protected climatic chambers and require extensive instrumentation.

A detailed analysis of the battery and its cells, temperatures and cell voltages have to be measured in many places. 100’s of measurement points with high common-mode level of the battery of up to 800 V, a highly isolated measurements required for safe testing.

On the Battery Test Stand, 20 x imc CANSAS-HISO8 measurement modules are used. Each module provides 8 highly-isolated inputs for measuring cell voltages or temperatures (thermocouples and PT100) at up to 800 V voltage levels simultaneously.

  • Sensor-break detection for thermocouples
  • Monitoring of measurement values according to min and max values (comparative operations)
  • Monitoring of implausible measurement value change by monitoring rise/fall (differentiation: result for rise/fall speed too high)
  • Monitoring if measurement values no longer change (differentiation: long-term average value and short-term mean value equal to zero)
  • Power failure with backup in ring buffer
  • Deactivation of test stand components possible
