RB21D Series Digital Display for Pressure Transmitters FAQs

Straight answers to what buyers ask us most about Digital LED Display Pressure Transmitter.

The RB21D Series Monitoring Display gives a local, real-time digital readout of pressure from a compatible pressure transmitter. It installs directly onto the transmitter and needs no external power source, which cuts installation time and wiring. It suits process industries, automation systems, hydraulic systems, water treatment facilities and manufacturing plants where operators need to read pressure at the point of measurement.

The RB21D has a 4-digit LCD with bar graph, a display range of -1999 to 9999, 0.1% accuracy and a sampling rate of 10 readings per second. It works with a 4-20 mA signal, connects through a DIN connector with 1+ and 2- terminals and is rated for a maximum operating temperature of 70°C. Display units are selectable and calibration is simple.

No, the RB21D does not need a separate power supply. It mounts onto a compatible transmitter through a DIN connector and works with the 4-20 mA signal, so no additional power cable has to be run to the display. This keeps wiring simple, saves panel space and makes it practical to add a local pressure indication to existing measuring points.
