Foil strain gages
Vishay Precision Group has released of a series of high-resistance miniature foil strain gages in an array of configurations including linear, half-bridge, full-bridge and shear patterns. These miniature strain gages are ideal in applications that can benefit from their small size and higher resistance. The new strain gages feature a modified-Karma alloy with gold-coated or copper-coated solder tabs, and an epoxy overcoat for grid encapsulation.
With increased resistance values, miniature strain gages are preferred when low power consumption is crucial, as in battery-powered devices such as electronic torque wrenches and testing equipment, and for applications such as wireless telemetry on rotating components. In addition, if the application demands the highest possible bridge output to improve its signal-to-noise ratio, the higher gage resistances will permit increased bridge excitation voltages.
CAS DataLoggers have partnered with dataTaker in developing the Series 3 dataTaker DT85 intelligent universal input data logger for machine monitoring applications. This automated solution measures physical value at high accuracy while connecting to a large number of inputs. The Series 3 DT85 data logger also features a communications suite, which makes it ideal for remote monitoring and real-time data acquisitions.
The data logger can store up to 10 million data points in user-defined memory and features independent control of schedule size and mode to log only as long as needed.
Meder Electronic has released the LI series of reed relays, an ultra-miniature relay ideal for use in high-voltage applications, including cable and in-circuit test equipment, high-voltage test equipment, photovoltaic application change-over switches, as well as the emerging electric vehicles market.
The updated LI series has been designed for high-voltage applications. The mechanical design features a new base plate that provides a stable relay structure and improves the electrical isolation between pins. The new base plate also prevents resin from wicking up the connection pins, improving the pins’ solderability. The resin filling process has a fully automated dispensing process that ensures consistent, high quality and uniform fill.
The product’s laser marking and date code are applied only after 100% final inspection.
Gigahertz-Optik has developed a cost effective measurement system consisting of the BTS256-LED tester and LPS-20-1500 LED power supply with S-BTS256 software to assist with single pulse light emitting diode (LED) binning. Both meter, power supply and control software work in tandem to drive and measure the test LED in single pulse mode and record the results.
The BTS256-LED tester is a compact measurement device designed for high accuracy measurement of luminous flux, spectral and color data of single assembled and unassembled LEDs in the visible spectrum. The BTS256’s bi-technology light sensor offers a fine photometric response photodiode for accurate wide dynamic range flux detection. Along with the integral detector, a compact low-stray light spectrometer is installed for spectral color measurements.
The LPS-20-1500 is a microprocessor-based current and voltage source designed for the operation of LEDs and other semiconductor light sources requiring low noise. The S-BTS256-LED software supplied supports the setup of the measurement device and source and the synchronized measurement.
Cerro Wire has announced its large print Max Print wire labeling system. Max Print enables contractors to easily identify the wire manufacturer and size, and view the sequential footage in large print.
With Max Print, gage size is printed 300% larger than standard labeling. This makes it easier and quicker to read gage size, which reduces errors and aids in the inspection process. It is ideal for use in warehouses and job sites where lighting is an issue.
Max Print is used in conjunction with Cerrowire’s True Sequential Footage, a sequentially printed cable reel that provides accurate wire length with each cut. True Sequential Footage prevents the need to carry excess cable inventory, providing precision length, accurate footage and cost control.
Koslow Scientific has released a portable instrument for passivation testing and validation of stainless steel equipment used in processing and transporting pharmaceuticals and food. The Passi-Flash 3036 resembles an oversized pen, works with all grades of stainless steel and is designed for single-handed operation.
The instrument tests steel’s passivity, producing an immediate pass or fail signal and displaying the measurement in millivolts. It features built-in memory to store readings, which can be downloaded to a spreadsheet, data file or other digital document. Stored readings are automatically date and time stamped.
