Difference between pressure transmitter and differential pressure transmitter
The pressure transmitter is equipped with a dedicated V/I integrated circuit with reliable operation, stable function, few peripheral devices, high reliability, simple and easy maintenance, small size, light weight, and extremely convenient installation and commissioning. Aluminum alloy die-casting shell, three-end isolation, electrostatic spray protective layer, solid and durable. 4-20mA DC two-wire signal transmission has strong anti-interference ability and long transmission interval. LED, LCD and pointer are three indicator heads, which are very convenient for on-site reading. It can be used to measure viscous, crystalline and corrosive media. High accuracy and stability.
Yucheng pressure transmitter
With regard to the service life of the pressure transmitter, the manufacturer now provides the service life guarantee for high-end and high-performance transmitters, but in fact, it is only a matter of time before these guarantees are extended to low-end products. In the near future, today's advanced technology, which is only available for high-performance transmitters, will be widely applied to low-end transmitters. At that time, the clear life guarantee will be very common.
Maintenance of pressure transmitter: the pressure transmitter is required to be overhauled once a month and inspected once a week, mainly to clean the dust in the instrument, check the electrical components seriously, and check the output current value frequently. The pressure transmitter is weak current inside, and must be separated from the strong current outside.
Differential pressure transmitter
The difference between pressure transmitter and differential pressure transmitter: differential pressure transmitter is the pressure of gas or liquid, in pascal (pa or bar); Pressure transmitter generally refers to the pressure of gas and liquid. In addition, there is also pressure sensor (force sensor) for pressure. The unit is Newton or kilogram (force) or ton. The differential pressure transmitter measures the pressure difference between two gases or liquids (in the container), which is a relative quantity; The pressure transmitter measures the pressure of a single gas or liquid (in a container), which is an absolute quantity. From the use point of view, there are two input nozzles for the pressure difference, which are respectively used to introduce two samples to be measured to obtain their pressure difference; There is only one nozzle under pressure.
