About This Product

Built for Continuous Industrial Monitoring

Electro-Med’s PRxx Process Indicator is a family of microcontroller based 4 1/2 digit and 5 digit process indicators, for 4-20mA signal input.

They sense signal from any closed loop current source and display the corresponding value of data.They can be interfaced with SCADA/PLC using analog retransmission output for process automation.They are used to display process parameters like flow rate, temperature, level speed, pH, power generation, temperature, pressure etc at remote locations in the plant.

Additional features like high/low limit settings, both side display etc can also be given if required. We have the facility to custom build the indicator to include any other feature required by the customer.

Custom display range and decimal point, field-settable
Senses value from any closed loop sensor
4-20 mA signal retransmission (Optional)
Both Side Display for wider visibility (Optional)
RS485 Communication (Optional)
High/low limit alarm relay outputs (Optional)
Built to order with any custom feature or enclosure
