Versatile setting capabilities
Zero and span can be adjusted as desired, enabling direct readout of measured values such as temperature, power, displacement, pH value, etc.
The indicator comes with a symbol set for standard engineering units. The symbols can easily be replaced. Settings are changed using switches and potentiometers. For parameter setting, you require an adjustable reference current source.
Loop-powered. Your advantage.
The digital indicators are simply inserted into the current loop like passive analog indicators, the voltage drop being approx. 3 V. Since power supplies and their wiring are not required, costs could decisively be reduced, allowing for displays which have been too expensive before. In addition, the reliability has considerably been improved since a power failure in the control room does not interrupt the data flow. And, in contrast to conventional digital indicators, there is no coupling between measuring loop and power supply.
