According to foreign media reports, HARMAN International (HARMAN InternaTIonal) announced on June 6 local time to launch a new 5G multi-frequency conformal antenna, which can be combined in a module and installed under the vehicle body panel. Modern intelligent networked cars may require up to 18 antennas to provide all relevant services to consumers, and they face many design and aesthetic challenges for automakers who want to make their products connectable while being simple and beautiful. Harman's multi-frequency conformal antennas are designed to meet these challenges. Harman International is a wholly-owned subsidiary of Samsung Electronics Co., Ltd., focusing on automotive, consumer and enterprise market connectivity technologies. Vishnu Sundaram, vice president of Harbin Intelligent Network's automotive information and communication business unit, said: "So far, car manufacturers have generally adopted "shark fin" antennas and various other antennas distributed around the vehicle. In the era of the increasing popularity of connected cars, This layout is no longer feasible for designers. Thanks to close ties with Samsung and several other original equipment manufacturer (OEM) partners, the Harman team designed a compact, beautiful and not outdated solution. Program." Harman's multi-frequency conformal antennas are designed thanks to Samsung's extensive experience in mobile antenna design, which can accommodate a variety of modern radio services, including LTE, Global Navigation Satellite System (GNSS), V2X, WiFi, Bluetooth. (Bluetooth), Remote Access Control (RKE) and electronic toll collection system. The antenna is mounted at the opening of the vehicle body panel - usually at the roof or at the trunk - and is worn with a waterproof, non-conductive radome. In addition to streamlined radio services, this multi-frequency conformal antenna can be integrated with Harman's Telematics Processor (TCU) as a "smart antenna." This 5G technology will help automakers keep up with the pace of innovation in telecommunications, allowing current and future drivers to stay connected without restrictions. As the car becomes more interconnected with its surroundings, this technology will also support safety solutions between the car and the car as well as the car and infrastructure, and will be expected to become the standard for the car. The bimetal thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the two metals have different thermal expansion, which drives the pointer to deflect to indicate the temperature.
WSS series bimetal thermometer is a kind of field measuring instrument for measuring medium and low temperature. It can directly measure the temperature of liquid, steam and gas medium in the range of - 80 ℃~+500 ℃ in various production processes. It is suitable for temperature measurement when the precision is not high in industry. As a temperature sensing element, bimetallic sheet can also be used for automatic temperature control.
The bimetallic thermometer can be divided into axial, radial, 135 ° and universal types according to the connection direction of the pointer plate of the bimetallic thermometer and the protective tube.

â‘ Axial bimetal thermometer: the pointer plate is vertically connected with the protective tube.
â‘¡ Radial bimetal thermometer: the pointer plate is connected with the protective tube in parallel.
③ 135 ° directional bimetal thermometer: the pointer plate is connected with the protective tube at 135 °.
â‘£ Universal bimetal thermometer: the connecting angle between the pointer plate and the protective tube can be adjusted at will.
