The application of pressure transmitter is very wide, and it is widely used in petroleum, chemical, metallurgy, electric power, food, paper, medicine, textile and other industries. Pressure transmitters are well maintained, and certain problems will be encountered in the process of use. What are the common problems? The following small series will come to you for a specific introduction.

The pressure transmitter is composed of a pressure sensor, a measuring circuit and a process connection. It can convert the physical pressure parameters such as gas and liquid felt by the pressure sensor into standard electrical signals to supply an indicating alarm device and a recorder. A secondary instrument such as a regulator performs measurement, indication, and process adjustment.
Common problems during the use of pressure transmitters:
1. What kind of connection is used between the pressure transmitter and other electronic devices. Is it necessary to use a short-distance connection ? If a long-distance connection is used, is it necessary to use a connector ?
2. The pressure transmitter needs to maintain stability after working overtime: most transmitters will “drift†after overtime work, so it is necessary to understand the stability of the transmitter before purchasing. It can reduce the troubles that will occur in future use.
3 , the pressure transmitter package. The package of the transmitter, especially often overlooked, is its frame, however this will gradually reveal its shortcomings in later use. In the purchase of the transmitter must take into account the future working environment of the transmitter, how the humidity, how to install the transmitter, there will be strong impact or vibration.
4. Whether an interchangeable transmitter is required . Determine if the required pressure transmitter can accommodate multiple operating systems. Generally speaking, this is very important. Especially for OEM products. Once the product is delivered to the customer, the cost of the customer's calibration is considerable. If the product is interchangeable, even changing the transmitter used will not affect the overall system.
5. What excitation voltage is selected. The type of output signal determines how the excitation voltage is selected. Many amplifiers have built-in voltage regulators, so their supply voltage range is large. Some transmitters are quantitatively configured and require a stable operating voltage. Therefore, a working voltage that can be obtained determines whether or not to use a sensor with a regulator. When selecting a transmitter, it is necessary to consider the operating voltage and system cost.
