Yokogwa EJA440A Gauge pressure transmitter
Yokogwa EJA440A Gauge pressure transmitter
Pressure transmitter is the most common industrial practice of a sensor, which should be widely
Used in various industrial automation environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electricity, shipbuilding, machine tools, piping, etc. Many industries. Here’s a brief description of some of the principles and application of commonly used pressure transmitter, pressure transmitter is used to measure liquid, gas, or liquid level, density and pressure steam, and then converting the pressure signal into 4 ~ 20mA DC output.
There are capacitive pressure transmitter pressure transmitter and the proliferation of silicon pressure transmitter, ceramic pressure transmitter, strain gauge pressure transmitters. Pressure transmitter Pressure range can be divided according to general pressure transmitter (0.001MPa ~ 35MPa) and differential pressure transmitter (0 ~ 1.5kPa), the negative pressure transmitter three.
