Overview of the current market and future development trends of pressure sensors

sensor technology

 

Sensor technology is one of the important technologies in modern measurement and automation systems. With the development of silicon, micromachining technology, VLSI technology, material preparation and research on properties, pressure sensors are applied to optical fiber sensors, high-temperature silicon piezoresistive and pressure sensors. Large-scale production of electrical junction sensors is possible, and pressure sensors have broad application prospects in biomedicine, micromechanics and other fields.

Because the pressure sensor technology involves a wide range of technologies, the discussion of pressure sensor theory, the application of new technologies and methods, and the research on new materials and new processes will become the development trend.

At present, there is an increasing demand for small pressure sensors in the market. These small pressure sensors can work in extremely harsh environments, require little maintenance, and have little impact on the surrounding environment. They can be placed in various vital organs of the human body to collect data without affecting people’s normal life.

And integrated pressure sensors have been increasingly integrated with other measurement sensors to form measurement and control systems. Integrated systems can increase the speed and efficiency of process control and factory automation. Because of the emergence of integration, some microprocessors can be added to the integrated circuit, so that the sensor has the functions of automatic compensation, communication, self-diagnosis, and logical judgment.

Starwin participated in China 2018 Beijing Refrigeration Exhibition

starwin exhibition

 

Co-sponsored by Beijing Branch of China Council for the Promotion of International Trade, China Refrigeration Society, and China Refrigeration and Air Conditioning Industry Association, and organized by Beijing International Exhibition Center hereinafter referred to as “China Refrigeration Exhibition”), will be held in Beijing China International Exhibition Center (New Hall) from April 9 to 11, 2018. More than 1,400 exhibitors signed up for the 2018 “China Refrigeration Exhibition”. This year’s exhibition will have industry-related companies and institutions from more than 30 countries and regions around the world participating in the exhibition, bringing together all the well-known brands in the global refrigeration, HVAC industry, including national pavilions from the United States, Europe, South Korea, and India. Nearly 60,000 professional visitors and users from more than 100 countries and regions around the world will come to visit and negotiate. “China Refrigeration Exhibition” was founded in 1987. After more than 30 years of unremitting efforts by the organizers, with the strong support of relevant government departments and the active participation of industry colleagues, along with the rapid development of my country’s refrigeration and air-conditioning industry, the exhibition has become a global event. One of the largest professional exhibitions in the industry, the exhibition also has two authoritative international certifications from the International Association of the Exhibition Industry (UFI) and the United States Department of Commerce (US FCS). “China Refrigeration Exhibition” has now shown a strong brand agglomeration effect, forming a diversified publicity and display platform based on exhibition and display, with high-end forums and conferences as the carrier, supplemented by network electronic communication means, and will integrate production, learning, Research, use, management and media are closely integrated into one. The theme of this exhibition is “improving quality and efficiency, developing in a balanced way, not forgetting the original intention, and creating the future together”, which is in line with the current political and economic situation in my country. Focusing on this theme, the organizer will hold a rich theme forum, special seminars and a number of technical exchange meetings during the exhibition to comprehensively analyze relevant national policies, focus on industry hot issues, industry technological innovation and future development directions. This exhibition will continue to carry out the “China Refrigeration Exhibition Innovative Products” recommendation activity, the ozone climate technology roadshow and roundtable conference will continue to enter the China Refrigeration Exhibition, in addition to open up related products and technical solutions area, organize target audience visits, carry out in-depth exchanges and many more Exhibition activities. The organizing committee will continue to advocate the development concept of green exhibitions and fulfill the social responsibility of the organizer.

 

At that time, Starwin (Shenzhen) Co., Ltd. will also be stationed in the museum with new products of micro differential pressure transmitter, micro differential pressure controller and micro differential pressure sensor; Star text invites you to participate in April 9, 2018 – April 2018 On the 11th at the China International Exhibition Center (New Hall) in Beijing, we brought a newly designed sensor/transmitter series to this exhibition, interpreting the new product definition in the industry, creating a higher-end standard system with Here comes a safer and more humane design and user experience.

When to Use NTC Thermistor Probes

ntc thermistor probes

NTC Thermistor Probes Have Endless Applications

NTC thermistor probes measure liquid levels and temperature in industries that extend from automotive electronics to medical technology to green energy. Their applications are endless, and their purpose ensures the operability of the applications they serve.

A thermistor probe, can also be as simple as an NTC thermistor chip, encapsulated with epoxy or glass. Or, it can be potted in a metal or plastic housing with two high-temperature insulated wire leads.

These NTC thermistors are in all the places that we live and work, from the moment we wake up and make coffee until the end of the day when we arrive home and relax in front of the television. They are indispensable to the cars we drive to work, the computers necessary to do our jobs, and the appliances we use to prepare food at the end of the day.

Understanding temperature sensing probes and their applications

It is essential to understand how NTC thermistor probes operate, in what capacity, and what their potential is. Part of this understanding includes the electrical properties of probes that abide by certain operating principles, including electrical resistance, responsiveness, pressure, and thermal conductivity.

Given their pervasiveness and range of applications, and despite many thermistor sizes and shapes, it is impossible to manufacture a universal NTC thermistor probe assembly. Temperature sensors used in automobiles are different from the temperature sensors used in wind turbines.

Thermistor probes in automotive innovation

Without thermistor temperature sensing probes, many automobiles, appliances, industrial equipment, and anything that requires feedback control would not function properly, or at all. Engineers depend on these NTC thermistor sensors as a design consideration for any product that generates energy, hot or cold, and requires temperature measurement, compensation, and control.

In 1966, automotive vehicles used around two thermistors per unit. This number grew to 60 thermistors per unit in the 90s, and today there are between 80 to 100 NTC thermistors in one vehicle. The exponential increase in temperature sensing devices parallels the complexity and refinement of technology. As automotive technology has increased and improved, so has the demand for temperature sensors. Car seat heaters, air conditioners, window defrosters, and oil temperature gauges require detection, regulation, and temperature control. Now, as electric vehicles become more common, NTC thermistors are used more than ever. Li-ion batteries in cars have become much more economical in the last 7-10 years. Thermistors are vital for maintaining an ideal battery temperature during the charge and discharge cycle. 

 Improving technology allows for more features and processes requiring accurate and reliable temperature sensing. For example, thermostats previously measured coolant temperature and controlled the cabin climate; today, thermistors have replaced thermostats as thermistors are faster, more accurate, and more reliable. NTC sensors can also detect oil levels and viscosity, alerting the driver when it needs to be changed.
