August, 2019 ABB Launches Smart Guided Wave Radars
Cary, NC — With the launch of its new smart LWT300 series, ABB is eliminating the need for the high lev- els of technical expertise traditional- ly required to operate guided wave radars. Instead, the expertise has been embedded into the measure- ment device, making it easy and sim- ple to use. This results in an opti- mized process, improved productivity and increased safety for operations personnel. The new LWT300 series, com-
prising LWT310 for liquids and LWT320 for solids level measure- ment, builds on the legacy of the MT5000 series of guided wave radars. Now including the powerful Level - Expert™ algorithm, it automatically
differentiates between the actual measured level and false signals. Operators simply need to enter instal- lation data and basic process condi- tions, and LevelExpert does the rest. Baseline mapping and echo
selection are no longer required, as the LevelExpert cuts through the noise and automatically reports the right level. Readings carried out are much more reliable. And because they are taken automatically, there is no longer any need for multiple manual adjustments by the operator. The new LWT300 series is

designed to perform at temperatures up to 400°F (204°C), under process pressures reaching 207 bars (3,000 psi), and to comply with the SIL2 cer-
tification for functional safety. This makes the measurement devices well-suited for reliable use in a wide range of applications,
including
industries where safety is a priority, such as oil and gas, petrochemical, chemical, power generation, water
and wastewater, and pulp and paper. Contact: ABB, 12040 Regency

Microchip Intros New Capacitive Touch Controllers
Chandler, AZ — To address electro- magnetic interference (EMI) and elec- tromagnetic compatibility (EMC) chal- lenges faced by developers of automo- tive touchscreens, three new maX - Touch® touchscreen controllers and optimization services are now avail- able from Microchip Technology. The TD family of touch con-
trollers offers a new differential mutual signal acquisition method that significantly increases the sig- nal-to-noise ratio (SNR). This allows the use of very thick glass or plastic
maXTouch touchscreen controllers.
cover lenses and multi-finger thick gloved touch support up to the equiv- alence of 0.2 in. (4.5 mm) thick poly- methyl methacrylate (PMMA). The MXT1067TD, MXT1189TD
and MXT1665TD devices add several variants that are cost-optimized for 9 to 13 in. (23 to 33 cm) automotive touchscreens to Microchip’s portfolio and are complemented by the recent- ly-introduced MXT449TD, MXT64 - 1TD, MXT2113TD, and MXT2912TD devices supporting up to 20 in. (50.1 cm) touchscreens. Each device ad - dresses aspects of the increasing demand for functional safety features and is designed in accordance with the Automotive SPICE Level 3 capability and ISO 26262 Automotive Safety Integrity Level (ASIL) B require- ments. All devices in the TD family pro-
vide waveform shaping capability to optimize the performance of the touch controller’s radiated emissions through an EMI optimization tool. Working with product experts in Microchip’s worldwide application design centers, this tool allows devel- opers to enter user-defined RF limits and tune the shape of the transmit- ted burst waveform used for the
touch sensing acquisition. Contact: Microchip Technology,
