One of the standout features of the RD150 is its seamless integration capabilities in HART multi-drop systems, enabling simultaneous monitoring of multiple sensors from a single display. This functionality not only enhances efficiency but also simplifies the overall management of your process variables, whether measuring level, flow, pressure, temperature, or weight.
The display supports easy configuration adjustments directly through its interface or via a PC using PACTware, making it ideal for users who require flexibility and precision in sensor management. With its broad operating temperature range from -40 to +85 °C and certifications for hazardous environments, the RD150 is a reliable choice for industries looking to optimize their processes while maintaining safety and efficiency.
The RD150’s display and adjustment module can be easily installed or removed without interrupting the device’s power supply. To install, simply unscrew the housing lid, position the module in one of four possible orientations (rotated by 90° each), press it into place on the electronics, and turn it to the right until it locks in securely. Once the module is in place, reattach the housing lid with the inspection window. Disassembly follows the same steps in reverse order. Please note, however, that RD150 does not support display modules with integrated Bluetooth functionality.
To configure the RD150 via PACTware, connect a PC to the device using an interface adapter. This setup allows for precise parameter adjustments on both the RD150 display and the connected sensor. Simply connect a USB cable from the PC to the interface adapter, and then link the adapter to the RD150. Once connected, PACTware enables easy configuration and adjustment of operational parameters, streamlining setup and calibration tasks for accurate process monitoring.
