Essential Specifications of the DMK 351 P Pressure Transmitter
The DMK351P Pressure Transmitter offers exceptional performance and versatility in pressure measurement applications. With a nominal pressure range from 0 … 40 mbar up to 0 … 20 bar, it can accurately capture a wide range of pressure levels. The transmitter provides two output signal options: a 2-wire configuration with a 4 … 20 mA output, and a 3-wire configuration with a 0 … 10 V output. Furthermore, the DMK351P comes with several special characteristics, including a hygienic version suitable for sensitive applications, and the availability of different process connections such as G1 1/2″, diary pipe, Clamp, and more.
It also boasts a high overpressure capability, ensuring reliability even in demanding conditions. The DMK351P offers optional versions, such as the IS-version Ex ia, which is intrinsically safe for gases and dusts. Additionally, it features a diaphragm made of 99.9% AI2O3, ensuring excellent durability. Moreover, the transmitter can be customised to meet specific requirements, allowing for the creation of customer-specific versions with special pressure ranges. Overall, the DMK351P Pressure Transmitter delivers outstanding performance and adaptability for a wide range of pressure measurement applications.
Applications
The DMK 351P Pressure Transmitter is well-suited for the food industry due to its hygienic design and the use of materials that are compatible with food processing standards. In this sector, the transmitter is typically used to monitor and control pressure in processes involving liquids, pastes, and semi-solid foods. Its flush-mounted diaphragm prevents the accumulation of residues, making it easy to clean and reducing the risk of contamination. This is especially important in applications such as dairy processing, beverage production, and the manufacture of sauces or creams, where cleanliness and product safety are paramount.
In the chemical and petrochemical industries, the DMK 351P is valued for its robust construction and resistance to aggressive media. The transmitter can handle corrosive liquids and gases commonly found in these environments, thanks to its high-quality stainless steel and optional special materials for wetted parts. It is used to measure and control pressure in reactors, storage tanks, and pipelines, ensuring safe and efficient operation. The transmitter’s ability to withstand harsh chemicals and its reliable performance under demanding conditions make it a preferred choice for process monitoring and automation in these industries.
The application of the DMK 351P in the paint and varnish industry is particularly notable due to its capability to measure pressure in viscous and sometimes abrasive media. Paints and varnishes often have high viscosity and can contain solid particles, which can clog or damage conventional pressure sensors. The flush diaphragm design of the DMK 351P prevents clogging and allows for accurate pressure measurement even in thick, sticky substances. This makes it ideal for use in production lines, mixing tanks, and filling systems where maintaining consistent pressure is crucial for product quality.
The transmitter is specifically designed to handle viscous and pasty media, which are common in industries such as food processing, cosmetics, and pharmaceuticals. These substances can be challenging to measure due to their tendency to block traditional pressure ports. The DMK 351P’s flush-mounted diaphragm ensures that even highly viscous or pasty materials do not obstruct the sensor, allowing for reliable and precise pressure readings. This feature is essential for processes involving creams, gels, pastes, and other thick materials, where accurate pressure control is necessary for consistent product formulation and process efficiency.
