The power supply of the temperature transmitter, most of them adopt 24V DC power supply which is the most used in industrial control field. Some manufacturers can also customize the 3-5V low voltage power supply according to the different needs of customers. Of course, there are also equipment manufacturers are designed according to other power supply voltage products or a wide range of power supply. In general, the power supply will not have a serious impact on the temperature transmitter, but the power supply if there is a problem, it is very likely to lead to damage to the temperature transmitter. Low supply voltage of temperature transmitter Temperature transmitter power supply circuit design in general is to leave a margin, in order to ensure that the temperature transmitter normal power consumption, the temperature transmitter can work normally. Even if the power consumption required for the normal operation of the temperature transmitter can not be met, the temperature transmitter just will not work properly and will not be damaged. High supply voltage of the temperature transmitter In general, the voltage should not exceed 32VDC, and exceeding this will basically damage the temperature transmitter. Even if by some chance no components in the power supply circuit are burned out, the service life of the transmitter will be reduced. Temperature transmitter using common power supply In many field conditions, it is common for multiple devices to share a common power supply. At this time, we should pay attention to whether there is a high-power equipment constantly start and stop, this phenomenon is very easy to produce interference, and even generate a surge, the temperature transmitter caused by serious impact or even caused by the destruction.
