Rangeable differential pressure (DP) sensors provide a high degree of flexibility in measurement applications by allowing users to adjust the output signal. This adjustability enables engineers and technicians to fine-tune the sensor’s response to match specific process requirements or compensate for changes in the system over time. This unique feature makes rangeable DP sensors ideal for a wide range of applications, from HVAC and flow measurement to filter monitoring and leak detection.

Rangeable DP sensors are specialized pressure measurement devices designed to provide versatility and precision in various industrial and research settings. Unlike traditional DP sensors with fixed measurement ranges, these sensors empower users to modify the output signal according to their specific needs. This adaptability proves invaluable in applications where process conditions may change or where a single sensor needs to serve multiple purposes.
Key Features
- Adjustable Zero and Span: Rangeable DP sensors allow users to elevate or suppress the zero point of the measurement range. This feature enables the sensor to accurately measure pressure differentials even when the baseline pressure is not at atmospheric pressure. Additionally, users can adjust the span, which effectively narrows or widens the measurement range to focus on a specific pressure region of interest.
- Versatility: Rangeable DP sensors cater to a wide array of applications, from monitoring filter pressure drops and flow rates to controlling pressure in pneumatic systems. Their adaptability makes them suitable for diverse industries and research settings.
- Cost-Effectiveness: The ability to adjust the range eliminates the need for multiple sensors to cover different pressure ranges, offering a cost-effective solution for pressure monitoring.
- Simplified Inventory: Rangeable DP sensors streamline inventory management by reducing the number of unique sensor types required, simplifying maintenance and replacement processes.
Adjustment Method Types
Rangeable DP transmitters offer various methods for adjusting the zero and span, catering to different user preferences and application requirements. Common adjustment methods include:
- Manual Configuration: Many rangeable DP transmitters feature push buttons, internal switches, or potentiometers that allow for manual adjustment of the zero and span. This method provides a direct and straightforward approach to configuring the sensor’s output signal. Technicians can use these physical controls to fine-tune the sensor’s response directly at the installation site.
- HART Communication: HART (Highway Addressable Remote Transducer) communication is a widely used digital communication protocol in industrial automation. Rangeable DP transmitters with HART capabilities can be remotely adjusted using a HART communicator. This method allows for convenient configuration and monitoring of the sensor from a central control room or a remote location. HART communication also enables access to advanced diagnostic information, aiding in troubleshooting and maintenance.
- Software Configuration: Some rangeable DP transmitters can be configured using dedicated software applications. This method provides a user-friendly interface for adjusting the zero and span, as well as accessing other sensor parameters and diagnostic data. Software configuration allows for precise adjustments and data logging, facilitating efficient sensor management.
The choice of adjustment method depends on factors such as the specific sensor model, the complexity of the application, and the accessibility of the sensor. Manual configuration is suitable for simple applications where direct access to the sensor is possible. HART communication offers remote adjustment capabilities and advanced diagnostics, making it ideal for complex applications or installations in hazardous or inaccessible locations. Software configuration provides a user-friendly interface and advanced features, catering to applications that require precise adjustments and data logging.
