Highly integrated, low-cost pressure transmitter solution

As a commonly used sensor in industrial practice, pressure transmitters are widely used in various industrial automatic control environments, involving petroleum, chemical, metallurgy, medical, environmental control and other fields. After decades of development, its accuracy continues to improve, and its functions are gradually powerful. However, the traditional separation scheme commonly used in the market increases the complexity of system design and delays the progress of new product development.

VMIVME-4140 The MAX40109 with the MAX32675 Industrial microcontroller provides a precise and reliable solution for gas or liquid pressure measurement in industrial processes. The system ensures the accuracy of pressure transmitters under harsh operating conditions and provides a new calibration method for traditional pressure sensors, reducing production complexity and cost. This innovation not only simplifies the calibration process, but also significantly reduces the size of the overall solution. ADI continues to innovate in the pressure sensor market, aiming to provide universal solutions that support a wide range of pressure sensor technologies to meet the growing demand for functional safety in the industrial market.

New changes in current detection and position sensing technology

At the production site, accurate current measurement is a key factor in ensuring efficient and safe operation of key equipment such as motors, frequency converters and power transmission systems. At the ADI booth, a non-contact current detection solution based on anisotropic magnetoresistance (AMR) sensors also attracted attention. With its high precision and convenience, this product provides a new solution for the current monitoring of equipment.

VMIVME-4140 “We made a contactless current detection reference scheme using the AMR sensor.” “The core of this solution is the AMR chip ADAF1080,” CAI said.

ADAF1080 is a single-axis, high-precision magnetic field sensor with integrated signal conditioning function. The high-current non-contact detection solution based on ADAF1080 breaks through the safety and reliability bottleneck of traditional current measurement methods, and has excellent magnetic field detection accuracy, linearity and low noise characteristics. It realizes non-contact monitoring of high current of large motor, transformer, cable and other equipment, and has a wide application prospect in high current scenarios such as new energy inverters and large motor drives.

CAI Zhenyu revealed that ADI will launch a single-chip Angle and multi-turn encoder position sensor ADMT4000 later this year, specifically designed to solve the problem of robot repositioning after power failure. The ADMT4000, with its unique technical characteristics, is capable of passively and contactless tracking multi-turn rotations, enabling accurate position monitoring without the need for power or physical contact. In addition, combined with single-turn sensors, the ADMT4000 can replace traditional gear reduction mechanisms, as well as linear sensors, greatly simplifying system design and reducing potential points of failure.
