Loop powered digital indicators

Alvi Technologies’ loop powered digital indicators can reduce costs as power supplies and their wiring are not required. This is because the indicators are simply inserted into the current loop like passive analog indicators.

The indicators provide a bar graph in addition to their digital display, which supplies all information on process variables at a glance. Furthermore, zero, span, and min/max outputs can be adjusted, enabling direct readout of measured values such as temperature, flow, displacement, pressure, pH value, and more.

Due to their microprocessor technology, the indicators do not require a high-precision external reference current for parameter setting. This means that even during operation, the settings can be changed without problems.
