DF51-14DEP-2C is a digital pressure gauge designed and manufactured by Shanghai Gucheng Instruments Co., Ltd, one of the leading pressure sensor and instruments suppliers in the industry. The DF51-14DEP-2C is a pressure transducer of differential pressure type. It is widely used in petroleum refineries, chemical plants, gas and oil pipelines, power plants, pharmaceutical plants, paper mills, breweries, wastewater treatment systems, and more. In addition to being reliable and provide precision measurements, it also has a robust design that can withstand harsh industrial environments.

The physical structure of the DF51-14DEP-2C is compact and relatively lightweight, allowing for easy installation in confined spaces. It includes a membrane and a cavity that produce differential pressure, which is then converted into an electrical signal by a sensor. The electrical signal is then fed to a signal conditioning unit, which in turn outputs a standard 1-5V, 4-20mA or RS485 signal. The signal is then used to display and/or control the pressure reading.

The DF51-14DEP-2C is non-linear, and therefore calibration of the pressure reading is required to ensure accuracy. This can be done either manually or automatically through software. The pressure range of the DF51-14DEP-2C is from -0.12MPa to +0.12MPa, and the media temperature range is from -20℃ to 80℃.

The working principle of the DF51-14DEP-2C is based on the capacitance-sensing technology. The pressure sensor is a capacitance-sensing diaphragm, which consists of two parts. The back side of the diaphragm is connected to a vacuum pressure port, and the front side is connected to a pressure port. As pressure increases on the front side, the diaphragm is stretched and capacitance increases. This change is detected by the sensor, which in turn is converted to an electrical signal and reaches the signal conditioning unit. The signal is calibrated to a standard signal (1-5V, 4-20mA or RS485) and is sent to a display or controller.

The DF51-14DEP-2C digital pressure gauge is a high precision, reliable and durable sensor for various applications such as petroleum refineries, chemical plants, gas and oil pipelines, power plants, pharmaceutical plants, paper mills, breweries, wastewater treatment systems, and more. The working principle of this pressure transducer is based on the capacitance-sensing technology, which ensures accurate and stable measurements under different pressures. Thanks to its robust design, it is capable of withstanding harsh industrial conditions. It includes a membrane and a cavity, producing differential pressure, which is then converted into an electrical signal and sent to a display or a controller.
