Product Description
The CD3A Pressure Transmitter is a cutting-edge and highly reliable device designed to accurately measure and transmit pressure signals across a wide range of industrial applications. Engineered with state-of-the-art technology and a focus on precision, durability, and versatility, the CD3A has become an indispensable tool for industries that require accurate pressure monitoring and control.
At the heart of the CD3A Pressure Transmitter lies its advanced sensing element. Utilizing a high-quality piezoresistive or capacitive sensing principle, this element is capable of converting applied pressure into an electrical signal with exceptional accuracy. The piezoresistive sensing technology, for example, relies on the change in electrical resistance of a semiconductor material when subjected to mechanical stress caused by pressure. This change in resistance is then precisely measured and converted into a standardized electrical output signal, ensuring a highly linear and stable response. Capacitive sensing, on the other hand, works by measuring the change in capacitance between two electrodes as pressure alters the distance or dielectric constant between them. Both sensing principles are carefully calibrated during the manufacturing process to guarantee outstanding measurement performance.
Features
The CD3A offers an extensive pressure measurement range, making it suitable for a diverse array of applications. Whether it is measuring low pressures in delicate gas handling systems or high pressures in hydraulic and pneumatic systems, the CD3A can handle the task with ease. It typically covers a pressure range from as low as a few millibars to several thousand bars, depending on the specific model and configuration. This wide range flexibility allows industries such as oil and gas, chemical processing, power generation, and water treatment to find a suitable CD3A variant for their unique pressure monitoring requirements.
In water treatment plants, the CD3A Pressure Transmitter is essential for monitoring the pressure of water in pipelines, pumps, and filtration systems. It helps to detect blockages, leaks, or abnormal pressure variations, ensuring the smooth operation of the water treatment process and the delivery of clean water to consumers. The transmitter's accuracy and stability are crucial for maintaining the proper pressure levels required for effective water treatment and distribution.
Product Overview
In terms of output signals, the CD3A provides multiple options to interface seamlessly with various control systems and data acquisition devices. Commonly, it offers analog output signals such as 4-20 mA or 0-10 V DC. The 4-20 mA current loop is particularly popular in industrial applications due to its immunity to electrical noise and the ability to transmit signals over long distances without significant signal degradation. This analog output can be easily integrated into existing control panels, programmable logic controllers (PLCs), and distributed control systems (DCS). Additionally, some models of the CD3A are equipped with digital communication protocols like HART (Highway Addressable Remote Transducer), Modbus RTU, or Profibus. These digital interfaces enable more advanced features such as remote configuration, diagnostics, and calibration, allowing for greater flexibility and ease of use in complex industrial networks.
Accuracy is a paramount feature of the CD3A Pressure Transmitter. With an accuracy specification often within ±0.1% to ±0.5% of the full-scale range, it provides highly reliable pressure readings. This level of accuracy is achieved through meticulous calibration procedures using high-precision reference standards during the manufacturing process. The CD3A also exhibits excellent long-term stability, minimizing the need for frequent recalibration. Even in harsh operating conditions, such as high temperatures, vibrations, or exposure to corrosive media, the CD3A maintains its accuracy over extended periods, ensuring consistent and trustworthy pressure measurements.
