The difference between a pressure gauge and a pressure transmitter is。。。。。

A: Pressure gauges are usually directly installed in pipelines, using the internal expansion tube to sense pressure and driving the gear mechanism to rotate the pointer to achieve the effect of displaying the pressure value

B: Pressure transmitters are generally used in industrial automation. Installed in a location where pressure reading is required, it may be a pipeline or a storage tank, converting gas, liquid, and other pressure signals into current or voltage signals. These current or voltage signals will be provided to instruments such as recorders, regulators, and alarms to achieve measurement, recording, and regulation purposes.
