Pressure Transmitter

Description

The PCI280 series pressure transmitters are designed to measure gauge pressure, vacuum pressure, and absolute pressure of gases, vapours, and liquids. Their stainless steel housing makes them ideal for industrial environments. Built-in circuits allow for the adjustment of zero and span.

The PCI280 pressure transmitter is suitable for measuring gauge, vacuum, and absolute pressure of gases, vapours, and liquids. The active sensing element is a piezoresistive silicon sensor, isolated from the medium by a diaphragm. The electronics are housed in a casing with a protection rating ranging from IP65 to IP68, depending on the type of electrical connection used.
