Panel meters play a hugely important role in industries or applications where monitoring or equipment control takes place. These meters display an input signal to give the user a reading and allow them to assess and monitor that signal, whether it is temperature, pressure, voltage or speed. As such, they can play an important role both in residential settings, for example, a central heating temperature gauge, and in industrial environments in which applications need to be closely monitored or controlled. Industries which use process control equipment rely on these meters. Many now feature cutting edge extras such as alarms and data transmission capabilities.
