压力变送器是一种将压力转换成气动信号或电动信号进行控制和远传的设备。H929049B0500主要由测压元件传感器（也称作压力传感器）、测量电路和过程连接件三部分组成。测压元件传感器能感受到气体、液体等物理压力参数，并将其转换成标准的电信号（如4~20mADC等），以供给指示报警仪、记录仪、调节器等二次仪表进行测量、指示和过程调节。

压力变送器的工作原理大致是：将水压这种压力的力学信号转变成电流（4-20mA）这样的电子信号，压力和电压或电流大小成线性关系，一般是正比关系。根据需要，压力变送器的输出信号可以是电动式的统一输出信号为0～10mA、4～20mA或1～5V等直流电信号，也可以是气动式的统一输出信号为20～100Pa的气体压力。

压力变送器的主要作用是将压力信号传到电子设备，进而在计算机显示压力数值。H929049B0500在各种工业自控环境中有着广泛的应用，如水利水电、铁路交通、智能建筑、生产自控、航空航天、军工、石化、油井、电力、船舶、机床、管道等众多行业。

此外，压力变送器还具备一些其他的特性，如双向通信功能，使其能够适应不同的应用需求。总的来说，压力变送器是一种重要的测量和控制设备，对于实现工业自动化和提高生产效率具有重要意义。


Pressure transmitter is a device that converts pressure into pneumatic signal or electric signal for control and remote transmission. The H929049B0500 is mainly composed of a load cell sensor (also known as a pressure sensor), a measurement circuit and a process connection. The pressure cell sensor can feel the physical pressure parameters such as gas and liquid, and convert them into standard electrical signals (such as 4~20mADC, etc.) to supply secondary instruments such as alarm, recorder, regulator for measurement, indication and process adjustment.

The working principle of the pressure transmitter is roughly: the mechanical signal of the pressure of the water pressure is transformed into an electronic signal such as the current (4-20mA), and the pressure and the size of the voltage or current are linear, generally proportional. According to the need, the output signal of the pressure transmitter can be an electric unified output signal of 0 ~ 10mA, 4 ~ 20mA or 1 ~ 5V direct current signal, or a pneumatic unified output signal of 20 ~ 100Pa gas pressure.

The main function of the pressure transmitter is to transmit the pressure signal to the electronic device, and then display the pressure value in the computer. H929049B0500 has a wide range of applications in various industrial automatic control environments, such as water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipelines and many other industries.

In addition, the pressure transmitter also has a number of other features, such as two-way communication function, so that it can adapt to different application requirements. In general, the pressure transmitter is an important measurement and control equipment, which is of great significance to achieve industrial automation and improve production efficiency.
