Rangeable Pressure Transmitters

Rangeable pressure transmitters, also known as adjustable range pressure transmitters, offer the flexibility to modify the 4-20mA output signal to match various pressure ranges. This adaptability reduces the need for maintaining a large inventory of transmitters with fixed ranges, making them a cost-effective solution for diverse process applications.

Rangeable pressure transmitters provide a significant advantage in process industries where pressure measurement needs can vary across different applications. These transmitters allow operators to adjust the pressure range without requiring specialized tools or interrupting the process. This capability simplifies installation, maintenance, and inventory management by enabling a single transmitter to cover a wider range of pressure measurement requirements.

Advantages

• Reduced Inventory: Minimize the need for stocking numerous transmitters with fixed pressure ranges.
• Increased Flexibility: Adapt to changing process conditions or different applications without replacing the transmitter.
• Simplified Maintenance: Easily adjust the range on-site, reducing downtime and maintenance costs.
• Cost-Effectiveness: Optimize investment by utilizing a single transmitter for multiple applications.

Range Adjustment Method Types

Rangeable pressure transmitters offer various methods for adjusting the output signal to match the desired pressure range. The most common methods include:

• Zero and Span Adjustments: This method involves adjusting the zero point (the output signal at the minimum pressure) and the span (the difference between the output signals at the maximum and minimum pressures). These adjustments are typically made using potentiometers or digital interfaces on the transmitter.
• Push-button Calibration: Some rangeable pressure transmitters feature push-button calibration, allowing operators to easily set the zero and span points by applying known pressures and pressing corresponding buttons on the device. This simplifies the calibration process and reduces the need for external calibration equipment.
• Digital Communication Protocols: Modern rangeable pressure transmitters often support digital communication protocols such as HART, PROFIBUS, or FOUNDATION Fieldbus. These protocols enable remote configuration and calibration of the transmitter using a digital communication interface. This method offers greater flexibility and precision in adjusting the output signal and allows for integration with advanced process control systems.
