Product Highlights

The DMP336 Pressure Transmitter is a versatile and reliable instrument designed for a wide range of applications. With a nominal pressure range spanning from 0 … 16 bar up to 0 … 1000 bar, it offers excellent flexibility in measuring pressures. The output signal of the transmitter is a 2-wire configuration, providing a reliable and standardised 4 … 20 mA output. However, other output signal options are available upon request. One of the standout features of the DMP336 is its media-wetted parts, which are constructed using special stainless steel. This ensures compatibility with various media types and enhances its durability. The transmitter is also designed to be insensitive to pressure peaks, allowing it to withstand sudden changes in pressure without compromising accuracy or performance. Additionally, the DMP336 boasts a high overpressure capability, further enhancing its reliability in demanding applications. For specific requirements, an optional version of the transmitter is available, offering an IS-version zone 0 Ex ia that is intrinsically safe for gases and dusts. Furthermore, the DMP336 is compliant with SIL 2 standards according to IEC 61508 / IEC 61511, making it suitable for safety-critical applications that require high levels of functional safety. Lastly, the transmitter is oil and grease-free, adhering to ISO 15001 standards, which is particularly beneficial for applications involving oxygen. Overall, the DMP336 Pressure Transmitter combines robustness, precision, and safety features to deliver accurate and reliable pressure measurements in diverse industrial settings.
