PI 300 Differential Pressures Transmitter

PI 300 Differential Pressures Transmitter

PI 300 Differential Pressures Transmitter is the most commonly used sensor in industrial productions. It is widely used in various industrial control environments, involved in water conservancy and hydro power, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemical, oil, electric power, ships, machine tools, pipes and so on.

According to the measuring range, pressure transmitter can be divided into three types: general pressure transmitter (0.001MPa~100MPa), differential pressure transmitter (0~ 1.5kPa), and negative pressure transmitter. It transmits pressure signal into electronic equipment and then the pressure is displayed by computer. Its working principle is to convert the mechanical signal like liquid pressure or gas pressure into electric signal like current or voltage.
