As one of the most commonly used physical parameters in daily life, temperature is related to the national economy and people's livelihood, and is widely used in all walks of life.
The powerful functions and convenience of Bluetooth temperature sensors allow them to be used in various areas of daily life.In particular, some sensors with mature and stable technology canWorking in harsh working environments of -40℃-70℃, it is suitable for various industries such as laboratories, warehouses, food freezers, smart homes, and central air conditioning monitoring in parking lots.In order to ensure that Bluetooth temperature sensors can be used normally in complex environments without affecting their accuracy, more and more manufacturers are currently conducting waterproof sealing tests on Bluetooth temperature sensors.
The picture below is the Bluetooth temperature sensor we are going to test today. From the appearance, we can see that the product is relatively small, and the outer casing is made of plastic. A chip that can transmit temperature is placed inside the product, so the entire product needs to be completely waterproof.According to the needs of customers and the structural characteristics of the product.Hairuisi sales engineers have formulated the following sealing solutions for customers.
1. Waterproof level:IP67
2. Test air pressure (simulated water pressure):14KPA
3. Leakage lower limit:11kpa
4. Leak limit:0.03kpa
5. Air intake time:5S, test time: 5S, voltage stabilization time: 5S
The above sealing test plan is based on the customer's products through multiple experiments and multiple test data on good and defective products. It is not applicable to all products.IP67 testing solutions are all like this. If your product also needs sealing testing, you are welcome to consult Hairis Technology to get a free waterproof testing solution for your product.
The waterproof testing method we use is to use compressed air instead of water to simulate the situation of the product in water.Because the product to be tested this time does not have an inflation port, it cannot be tested by directly inflating the product.We make a copy mold according to the shape of the product.The more precise the mold is made, the smaller the gap between the product and the mold, and the more accurate the test results will be.
The first step in testing is to place the tested product in the prepared mold. After the upper and lower molds are sealed, the test pressure adjusted in advance will enter the mold through the air pipe. After a certain test time and pressure stabilization time, we can visually observe from our instrument screen whether the compressed air in the mold has entered the inside of the product. If the air pressure in the mold continues to decrease, it means that the air pressure in the mold has leaked into the product.Our air tightness testing equipment will determine whether the tested product is based on the amount of air pressure drop and leakage.OK product or NG product.
Our instruments can also be equipped with barcode scanners to directly export product test results to provide data support for subsequent product quality tracking.
Hairis air tightness testing equipment is divided into six categories. The one used to test the Bluetooth temperature sensor this time is ourHC classic series air tightness testing equipment.This device comes with two testing methods, positive and negative pressure, and has high stability. It is also the one most chosen by customers.In addition to this model, the company has also launched the HL Leader Series, HP Pioneer Series, and HN Embedded Series according to customer and market needs. In 2019, the company once again launched a true water detection equipment that can test breathable membranes, which we define as HW true water detection equipment.If you want to know more about our products, please call Hai Ruisi Technology.
