Choosing the Right Hardware for Testing in Harsh Environments

Testing in rugged applications often includes testing in extreme temperature ranges, which can add constraints to hardware. Cold-start engine testing, for example, uses a test cell that can drop to -40 °C and requires continuous data acquisition such as temperature, pressure, and other various measurements. Placing hardware that is not built to withstand this range into harsh environments can cause components within the hardware to work incorrectly and result in incorrect data or damage to the hardware.

Measurement Terminal

The EL3751 EtherCAT terminal from Beckhoff Automation (Savage, MN) provides measurement as part of a standard I/O system. It acquires data at 10,000 samples per second and provides measurement accuracy of ±0.01% for most interfaces at 25 °C, and 24-bit resolution. Parameterization options are available for the analog input, which supports measurement functions U, I, R, DMS (strain gauge), and RTD. Optionally, measured data can be transmitted to higher-level automation devices with oversampling. The integrated distributed clocks ensure synchronized sampling across the EtherCAT system. Available measurements include voltage, current, resistance, electrical resistance, RTD, strain gauge/load cell, and potentiometer. For Free Info Visit http://info.hotims.com/61064-400

Digital Measurement

Siemens (Munich, Germany) offers Flender Gearlog digital measurement technology for gears that captures values relating to rotational speed, torque, temperature, and vibration using special sensors that record important physical variables. The aim is to compare operational load spectra with the fatigue strength of individual gear unit components over time to match up the gear unit and the working machine for the long term. The system adds up these readings in parallel with machine capacity utilization. The measurement results are logged, saved, and digitally depicted in compressed form. Operators are able to visualize the results at any time or read them out in the form of a dataset. The measurements enable conclusions to be drawn about the applied load and loading capacity of gears, and can be used to identify possible sources of damage, capacity reserves, and overloading in the measured gear.

Bit Error Rate Tester

Keysight Technologies (Santa Rosa, CA) introduced the M8040A bit error rate tester (BERT) for testing PAM-4 and NRZ devices that operate up to 64 GBaud. Engineers in validation labs and R&D who characterize receivers on the physical layer for the next generation of data center interconnects can use the device for test setups and repeatable results. The pattern generator module provides built-in deemphasis, jitter injection, and an optional second channel. Users can select PAM-4 and NRZ in the user interface, eliminating the need for external combiners, cabling, and de-skew to provide PAM-4 signals. For best signal quality, remote heads reduce the distance to the device under test. For Free Info Visit http://info.hotims.com/61064-402

Friction Tester

Paul N. Gardner Co. (Pompano Beach, FL) offers a compact CFT friction tester that provides detailed information of the slip characteristics of packaging material. Surface slip is a key factor when printing, erecting, or filling packaging materials on an automatic line. The CFT measures both static and dynamic coefficients of friction. A sample of 2.5 × 2.5" with a weight acting over the entire surface area is moved over another sample at a given speed. Static and dynamic coefficients of friction (COF) are automatically calculated and displayed on-screen. Features include graphical representation of forces during test, and pre-loaded ISO/ASTM/TAPPI test methods. For Free Info Visit http://info.hotims.com/61064-404
