What is the best sensor temperature management technology for brainstorming over temperature management in extreme environmental conditions? Author: Honeywell Sensing and Control global product marketing manager Jacqueline Leff In medical applications such as CPAP machines, ventilators and other respiratory devices such as sleep ventilators and anesthesia machines, it is important to be able to accurately monitor and manage both temperature and humidity measurements simultaneously. In the past, implementing both tests required the installation of two different sensors on a single circuit board with all the necessary electronics , then encapsulated around the cell. However, the Honeywell HumidIcon â„¢ digital / temperature sensor requires only a combination of temperature and humidity sensors in a single package in a relative humidity family that allows design engineers to use a single package that contains all the information, programs, and I / O ) Of pre-certified sensor components. The combination of the two sensors and all the related connections, procedures and information makes the design of the end product easier. The ultra-small package offers great flexibility, takes up less PCB (printed circuit board) space, and simplifies installation on congested PCBs or smaller devices. Honeywell HumidIcon â„¢ digital / temperature sensors require only true digital temperature-compensated I2C output at relative humidity, enabling customers to remove the associated signal conditioning components from the printed circuit board (PCB), freeing up space and reducing the need for these components The associated costs also eliminate the problems that may occur due to multiple signal conditioning components on the PCB. At the same time, the combination of many components into a single module makes it easier for OEMs to develop the next generation of products using the same sensor components without having to redesign or recertify the sensor section. Honeywell HumidIcon â„¢ digital / temperature sensors require only multi-layer structures at relative humidity to withstand the most dirt, dirt, oil and common chemical attacks. In addition, it has a hydrophobic filter and anti-condensation function, can be used in a variety of condensing environment. Stable performance is the most important sensor standard. Honeywell HumidIcon? Digital / temperature sensor series with industry-leading long-term stability, drift of five years 1.2% RH. Most humidity sensors in the industry typically require 12 hours of rehydration (requiring a special equipment room) in a 75% relative humidity environment to correct for back-flow temperature offsets, whereas Honeywell's sensors only need to operate at greater than 50% relative humidity for 5 hours under the conditions of rehydration. This long-term stability minimizes system performance issues. The sensor does not require service or replacement over its useful life, ensuring system uptime and eliminating the need for complex and expensive recalibration on a regular basis. .
Organic pigments are further divided into two subgroups:
Natural Organic Pigments And Synthetic Organic Pigments
Common types include azo pigments, lake pigments, phthalocyanine pigments and quinacridone pigments. They are all artificially synthetic organic compounds. The intermediate, synthesis process and equipment required by such kind of pigments are generally the same as that required by organic dyes, therefore usually manufactured in the dye industry. However, as pigments, they are, after all, different from the organic dyes.
