MEMS Sensor WPAS01
Summary:
The WPAS01 series is a plastic-encapsulated pressure sensor packaged with high-precision MEMS pressure-sensitive chips and mature production processes. The standard pin structure is convenient for customers to use, and at the same time, it provides OEM customers with low-cost plastic-encapsulated pressure sensor solutions. WPAS01 series plastic packaged pressure sensors are only suitable for dry and non-corrosive gases. Different ranges and output methods can be customized according to customer requirements.
Feature:
* Package form: SOP8
* Wide operating temperature range: -40℃～125℃
* Not temperature compensated
* Suitable for module assembly
* High precision at room temperature: 0.2%FS
* Low cost and small size
* High reliability

APPLICATION
Industrial Combustible Gas Alarm
In the process of industrial use of combustible gas, if the combustible gas is in an incomplete combustion state or has gas leakage, etc., the combustible gas will cause personnel poisoning or fire accidents, directly threatening the life safety of personnel. Therefore, it is necessary to install an industrial-grade gas alarm. If the gas exceeds the standard in the on-site environment, the alarm can give an early warning, thereby reducing the probability of danger.
Urban underground pipe gallery is a municipal public facility that implements unified planning, design, construction and maintenance, and is built in the city underground for laying municipal public pipelines.During the construction of the urban underground comprehensive pipe gallery, the workers are actually working in a closed environment or a closed space.
The combustion gas used in the city is supplied to urban residents from the gas source point through the gas distribution and supply system. The main component of the gas distribution system is the gas pipeline. Compared with other pipelines, the tightness of gas pipelines has particularly strict requirements,
As we all know, there are a lot of pollutants in swimming pool water, and the polluted water can easily become a source of transmission of some diseases, causing various discomforts to swimmers. Therefore, the use of online water quality monitoring equipment for real-time monitoring and strict filtration and disinfection of pool water is an important link to prevent the spread of various diseases, protect swimmers and improve the quality of pool water.
The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.
Livestock and poultry farming is the major emission of ammonia gas, and these ammonia gas react with the oxidation products of sulfur dioxide and nitrogen oxides to generate ammonium nitrate and ammonium sulfate, which are an important source of PM2.5.
