Temperature Transmitters

The Sitrans TH320/420 and TR320/420 WirelessHART (Highway Addressable Remote Transducer Protocol) temperature transmitters from Siemens, Erlangen, Germany, are available for a range of sensor types suitable for mounting in sensor heads and rail mounting. The devices provide reliable results even under extreme conditions up to -50 °C. The use of the Callendar-van Dusen method or 60-point curve ensures measuring accuracy. Deviations can be detected and monitored through the drift detection with dual-channel transmitters. Electronic device descriptions (EDD, DTM, and FDI) allow the transmitters to be used in all current distributed control systems.

Signal Analyzers

Anritsu, Allen, TX, offers the MS-269xA signal analyzers for verifying legacy 4G LTE and LTE-Advanced products, as well as 5G NR designs. An optional built-in vector signal generator conducts additional measurements on sub-6-GHz designs. The analyzers can conduct EVM measurements of <0.5% using wide-dynamic-range performance. EVM measurements are optimized by a built-in, one-button Auto-Range function in the signal analyzers. The analyzers also feature DANL of -151 dBm/Hz from 6 to 10 GHz for increased dynamic range.

3D Printing Software

CoreTechnologies, Southfield, MI, released 4D_Additive software that enables CAD data of all major 3D formats to be processed for 3D printing. Healing functions for CAD models automatically fill gaps and correct overlapping elements, twisted faces, and other geometry errors. In interactive mode, filter functions allow users to locate the geometry errors and fix them with the help of cleanup functions. Other features include checking, healing, and repair features; analysis of models for additive methods; geometry optimization for additive processes; and nesting and optimization of the building platform.

Power Inductors

TT Electronics, Carrollton, TX, introduced the HA66 Series of SMD power inductors for use in high-power-density applications where size is critical. The low-profile inductors are suited for high-efficiency DC-DC converters using high switching frequencies up to 3 MHz, as well as EMI and low-pass DC filters. The low-loss, ferrite-based inductors feature inductance ratings from 2.5 to 220 pH, DC resistances from 0.018 to 0.820 Ω, and Irms values from 1.22 to 11.2A. They are magnetically shielded, have low DC resistance, and have an operating temperature range of -40 to +125 °C.
