The IGP20 series single flange remote transmission pressure transmitter can accurately and reliably measure gauge pressure or liquid level. In addition to outputting a standard signal of 4-20mA DC in a two-wire system, it can also provide digital signal output using the HART (Highway Addressable Remote Transformer) protocol or FF (FOUNDATION Fieldbus) fieldbus for convenient remote configuration and monitoring using software. All transmitters have on-site digital displays that intuitively indicate the measured pressure. The LCD multi segment display of intelligent products can display measured pressure, transmitter output current, or range percentage, and display the measured value percentage in the form of a bar graph. When the transmitter fails, the LCD indicator will display an alarm message. The transmitter can be easily recalibrated. The transmitter is equipped with on-site buttons, which, when combined with LCD parameter indicators, can be easily set up on site. The product adopts a standard modular design with the same upper structure, which can be easily replaced or upgraded. Sensors offer a variety of optional materials to meet different on-site needs. When the transmitter needs to maintain isolation during the same process, it can be equipped with a remote transmission or directly installed pressure isolation diaphragm box. The membrane sealed isolation system is suitable for process fluids that are corrosive, viscous, high-temperature, toxic, have hygiene requirements, or are prone to accumulation and condensation. The product is suitable for measuring liquid, gas, and vapor media, and is widely used in petrochemical, power station, metallurgy, pharmaceuticals, food, shipbuilding, and all other industrial applications.
