The Spring Festival of 2024 is approaching, and some colleagues of the company have begun to rehearse the programof the annual meeting. Today's weather in Xi 'an, overcast, 

seems to have been brewing a light snow or light rain, butcan not see a shadow, gray days, give people a feeling of depression, hope or snow or rain quickly come, wash haze  in 

the air.

    All of the previous "Small Talk about Sensor Series" was written on a business trip. Today, this article is a little special,no business trip, written in the company, can also be said to 

be a virtual business trip, business trip - the United States.

    Because, this afternoon with our three colleagues, went to the United States to participate in the 2024 ChicagoRefrigeration Show AHR discussion, to share some of the situation.

    Xi 'an Chinastar M&C Ltd this year is the tenth year to participate in the United States refrigeration exhibition, due to the epidemic, three years did not go, plus visa reasons, so the middle empty for four years. AHR is a large refrigeration show in the United States, which takes turns in several cities in the United States, Chicago, Las Vegas, Orlando, Atlanta, New York, Dallas, taking care of different manufacturers in the South and North of the United States.

    The booth decoration and placement requirements of the United States refrigeration exhibition are in accordance with their format, unlike most Chinese exhibition companies' standard booth 3×3 meters, high isolation board separated by an independent file, and even can not see the products of the booth next door. The United States refrigeration exhibition is not the same, they require no shelter, standing in their booth, around the neck you can see the products on both sides of the booth, visitors from a distance can see a lot of company Logo, it is easy to find the company you want to visit.

    Xi 'an Chinastar M&C Ltd pressure temperature sensor focus in the field of air conditioning refrigeration has been more than a decade, although this industry competitors are very strong, but Xi 'an Chinastar M&C Ltd in this field still has a lot of advantages, in the face of the world famous companies Sensata, Danfoss, Emerson and other powerful companies, we still have their own advantages, we have also gained a lot of famous company customers. Some refrigeration industry customers, recognized the company's quality, cost-effective, has been working with more than 15 years.

    This year's American refrigeration exhibition, we mainly brought a strong competitive, mainly used for water cooling units to measure refrigerant all-welded MEMS pressure transmitter PT300G, 4-20 mA output, strong anti-interference ability, no leakage, with high cost performance, and won the love of many customers. Mainly used in energy storage air conditioning and other refrigeration equipment, of course, can also be used in other measurement gas, liquid, with the appropriate range and accuracy of the pressure measurement equipment.

    Air source heat pump is a more popular low-carbon heating method today, limited by the total cost, the cost of the pressure sensor is lower, to this end, we launched PT1800 series using ceramic capacitive pressure sensor core system made of pressure transmitter, according to different customer requirements, Can be made into 0.5-4.5V and 4-20 mA output, in the United States refrigeration show has also been welcomed by users.

    With the application of the IOT in the refrigeration industry, wireless sensors are more and more favored by customers, some customers as the pressure acquisition on the production line equipment, as a flexible transformation component of the intelligent or automated production line; Some customers as a remote monitoring of refrigeration equipment, through the router directly connected to the internet can remotely monitor the working status of larger refrigeration equipment; In addition, in some application environments, you can directly use the mobile phone to measure the pressure of the system on the spot, and you can also set up alarm points, which is very convenient to monitor the pressure or temperature of the equipment. If the acquisition frequency is not very high, a battery can be used for 5 to 6 years, as a new wireless low-power pressure sensor and temperature sensor, has been welcomed by many American users. These applications all fall under the umbrella of the IIOT.

    Due to the expansion of the American market for many years, so we have a lot of customers in the US, there are also many European customers to the US to participate in the refrigeration exhibition, mutual exchange is always beneficial. Our colleagues invited European clients to try local Chinese food in Chicago. There are also local American customers who invite our colleagues to taste American food.

    In addition, some small details will also make our exhibition more accurate. For example, American customers prefer to use Psi as a unit of pressure, while European customers prefer to use Bar. Do not overestimate the mathematical level of Americans and convert 1000 Bar into ** Psi on the spot. It takes a lot of trouble. Therefore, for American customers, we will always use Psi as a pressure unit, neither Bar nor the so-called international standard unit Kpa.

    Four years did not participate in the United States exhibition, as many years to participate in the US refrigeration exhibition colleague Eva, felt that the number of visitors this year's refrigeration exhibition than the annual number of people before the epidemic. Instead of seeing the decline of the American economy, it seems that there is a lot of optimism everywhere. But prices in the United States have risen a lot, whether it is housing or dining.

    Remember that when the epidemic goes to the US to participate in the exhibition, if you eat ordinary Chinese buffet, it is eight dollars to ten dollars per person; If you spend $14, $15 a person on a Chinese buffet, you'll have lobsters and crabs, all kinds of things. This year, the average Chinese buffet has risen to more than ten dollars, even 19.90 dollars, and there is no lobster or crab. The same housing standard, which was $100 four years ago, is now mostly mentioned at $140 a standard room. Ha ha didn't bother to ask, is the housing tip increased? 

    According to recent reports, the US GDP growth of 2.5% in 2023 is very good, I do not know whether the strong US economy and rising prices are one of the factors.
