Differential Pressure Transmitters: Reliable Solutions for Accurate Measurement

Differential pressure transmitters (DP transmitters) are essential instruments used across various industries to measure the pressure difference between two points within a system. They play a critical role in applications such as flow measurement, level monitoring in tanks, and detecting pressure drops across filters. At Pondus Instruments, our PT600 and PT60 T-model series are designed to provide precise differential pressure measurement for both liquid and gas environments, ensuring stability and reliability in critical processes.

How Differential Pressure Transmitters Work

Differential pressure transmitters measure the difference in pressure between a high-pressure side and a low-pressure side of a system. This differential pressure is used to derive various parameters such as flow rate and fluid level. For instance, a DP transmitter like the PT600 measures the flow in pipes or the level in pressurized tanks by assessing the pressure difference across an obstruction, which creates a pressure drop proportional to the flow rate. This value is then digitally processed, offering accurate and stable readings even under fluctuating conditions.

PT600 Series: Versatility and Robust Design

The PT600 series by Pondus Instruments offers a robust solution for differential pressure measurement. The stainless-steel construction ensures durability, while the capability to withstand one-sided pressure up to 150 bar makes it highly reliable in demanding applications. This series is ideal for flow and level measurement in both liquid and gas systems, as well as differential pressure monitoring across filters. Thanks to its innovative design, the PT600 provides minimal influence from temperature changes and line pressure, which is crucial for maintaining accuracy in dynamic environments.

PT60 T-Model: Hygienic Solution for the Food, Dairy, and Pharmaceutical Industries

The PT60 T-model is specifically designed for level measurement in pressurized tanks within industries that require high hygienic standards, such as food, dairy, and pharmaceuticals. This differential pressure transmitter features multiple hygienic process connections and is housed in a stainless-steel enclosure with an IP67 rating, making it suitable for rigorous cleaning procedures and ensuring long-term reliability in sensitive environments. Its precision and ease of installation make it an excellent choice for industries where maintaining a clean and controlled environment is of utmost importance.

Innovative Solutions with Dual Sensor Technology

Our PT600 series also features a unique dual-sensor solution that digitally links two independent pressure sensors for enhanced accuracy in differential pressure measurement. This configuration is perfect for level measurement in closed tanks and for monitoring differential pressure across filters, without the need for traditional remote seals and capillary tubes. This approach reduces installation complexity, minimizes errors due to temperature variations, and provides easy maintenance, making it a cost-effective solution for many industrial applications.

Applications and Benefits of Differential Pressure Transmitters

Differential pressure transmitters are commonly used in several applications:

• Flow Measurement: differential pressure transmitters are used to measure flow rates in pipes, using constrictive elements like orifice plates to create a pressure drop proportional to the flow rate.
• Level Monitoring in Pressurized Tanks: Particularly useful in monitoring fluid levels in sealed or pressurized vessels, such as those found in industrial or pharmaceutical environments.
• Filter Condition Monitoring: By measuring the pressure difference across filters, differential pressure transmitters can help identify clogging and indicate when maintenance is required, thus preventing downtime and maintaining system efficiency.

The accuracy, versatility, and robustness of differential pressure transmitters make them indispensable tools in a range of industries, from food processing and pharmaceuticals to heavy industry and utilities. With advancements in technology, including wireless monitoring and integration with Industrial IoT (IIoT), differential pressure transmitters are evolving to offer enhanced diagnostic capabilities and easier maintenance, paving the way for improved operational efficiency and safety in industrial settings.
