VMICPCI-7806-211000 Comparison of traditional and digital temperature sensorshttps://www.gsplcdcs.com/
VMICPCI-7806-211000 Temperature sensor is the core of temperature measuring instrument, its variety, in a variety of industries are widely used. Today, temperature sensors in the market are generally divided into traditional temperature sensors and digital temperature sensors, so which is better? Here is a brief comparison for learning. From China Sensor Trading Network
Temperature sensors on the market can be roughly divided into traditional temperature sensors and digital temperature sensors, both of which are widely used. These two sensors have their own characteristics and applications, now can not completely say which is good which is not good, at present can only say that each has its own advantages.
VMICPCI-7806-211000 The digital temperature sensor is different from the traditional thermistor, the use of integrated chip, the use of single bus technology, it can effectively reduce the external interference, improve the measurement accuracy, at the same time, it can directly convert the measured temperature into a serial digital signal for microcomputer processing, the interface is simple, so that data transmission and processing simplification. The integration of some functional circuits makes the overall hardware design more concise, can effectively reduce costs, build circuits and welding circuits faster, debugging is more convenient and simple, which shortens the development cycle.
VMICPCI-7806-211000 Most of the traditional temperature detection with thermistor as a sensor, the use of thermistor, can meet the 40 degrees Celsius to 90 degrees Celsius measurement range, but the thermistor reliability is poor, low temperature measurement accuracy, for 1 degree Celsius signal is not applicable, but also through a special interface circuit converted into digital signals can be processed by the microprocessor.
The main categories of mechanical pressure switches include normally open and normally closed. The main features are:
1, the use of British pipe thread quick joint or copper pipe welding installation structure, flexible installation, easy to use, no special installation fixed.
2, the chip wire connection can be selected by the user.
4. Sealed stainless steel sensor is safe and reliable.
5, the pressure range can be manufactured according to the pressure value selected by the user.
VMICPCI-7806-211000 Electromechanical pressure switches instead of various mechanical mechanical pressure switches have gradually become the mainstream of applications. Usually there are mechanical pressure switch pumps, are some high pressure pumps, such as the pump to send water to the tall building, in order to reach a certain pressure, the pump shut down, to avoid no load but the pump has been turning, waste of electricity, while the role of the storage tank will not let the pressure immediately lost, so not a lot of water pump will not start. When the pressure of the tap water pipeline or air pump is less than the lower limit of the switching pressure adjustment point, the switch is automatically switched on and the pump starts to operate. When the pressure of the tap water pipeline or air pump is greater than the upper limit of the switching pressure adjustment point, the switch is automatically disconnected and the pump stops running. The upper and lower limits of the switching pressure can be adjusted within the adjustment range with the difference of the water height and the pressure required by the air pump.
