How to choose the sensor guide

Sensors can monitor what is very much the scope of application is very extensive , it is also in the choice of the sensor can not be blind choice , requires a certain skill . Select a deciding factor when the sensor is working environments. Some industries ( such as food and automotive industries ) work environment may be dirty or dangerous , or both. In processing food , the humidity may be higher and have a lot of liquid. Processing engine or other parts of the automobile factory workshop, there may be sand , lubricants and coolants . In this case , the sensor must be considered environmental adaptability , if the sensor can not be used not meet environmental dirt . Such considerations also affect the required detection range because Coolant Temperature Sensor may need to be placed in harsh environments outside a distant location ( rather than on the desired location ) . If the light is dirty or signal weakened, then proactively alerting and notification is helpful. Similar environmental problems will affect the sensor size , the size can vary from smaller than a finger into the open palm bigger than that . Large size than the small size of the sensor to the sensor , since all the components are incorporated into a small space, higher cost . Small size of the area to collect light Crankshaft Sensor Replacement is smaller, a detection range of smaller, lower optical performance . To overcome these shortcomings , the small size of the sensor in order to better match the physical space available . Again, in the semiconductor clean room equipment used in the work environment is not bad sensor though , but must work in confined spaces . At a distance of typically a few inches , so Car Temperature Sensor are generally small. These sensors often use fiber to the light import ( or export ) detection zones . Installation and the price is a factor to consider is to install the system . Sensors typically require a box or other means for mechanical protection. This mechanical and optical protection costs may be greater than the cost of the sensor itself is also high, so is the need to consider when buying an important factor . If the firm has a flexible mounting system , as well as protection for the sensor mounting arrangement , the product is easier to achieve and live longer .
