All about Industrial HMIs
What is an Industrial HMI?
An industrial human machine interface (industrial HMI) provides operators with machinery performance data and allows them control via a terminal. Real time information is displayed in graphs, charts, and digital dashboards with notifications and alarms. HMIs can have touch display panels, push buttons, computers with keyboards or be mobile devices. Traditional computers lack the durability of industrial HMIs because they break down due to infiltration by dust and debris or deteriorate due to intense temperatures and conditions. Industrial HMIs are designed with the hardware and software for industrial applications and systems. By allowing machinery to communicate directly and automatically with the industrial HMI, there is less human error in manual measurements.
Where are Industrial HMIs used?
Industrial HMIs are used in a variety of industries. They are used in industries such as pharmaceuticals, food manufacturers, robotics, and oil processing.
Industrial HMI Design
The design of industrial HMIs must consider protection from extreme environments, liquids, dust and debris. Industrial HMIs must be durable, as they are difficult to replace. The interface must balance the ease of use with the ability to display all requisite data. For industrial HMIs with touchscreens, there are two types: capacitive touchscreens and resistive touch screens. Capacitive touch screens respond to electrical charges given off by human touch and resistive touchscreens respond to pressure of a finger or a stylus.
