Danfoss 060G3203 MBS 3300 Flush Diaphragm Pressure Transmitter

Product Overview

The Danfoss 060G3203 is a high-precision pressure transmitter from the MBS 3300 series, specifically designed for applications where hygienic or viscous media monitoring is required. Featuring a flush diaphragm design, this transmitter eliminates the dead zones typically found in standard pressure ports, making it ideal for food and beverage processing, pharmaceutical manufacturing, or any process involving media that could clog a traditional recessed sensor. Built with an ATEX-approved, rugged construction, it ensures reliable performance and safety in demanding industrial environments.

Technical Configuration

The 060G3203 is engineered to provide stable, repeatable measurements while resisting media buildup and clogging.

• Flush Diaphragm: The sensing element is mounted flush with the process connection, ensuring that the media flows directly across the diaphragm without creating pockets where residue or bacteria could accumulate.
• Signal Integrity: It provides an industry-standard 4 - 20 mA output signal. With factory-set clipping levels (3.6 mA low / 22.4 mA high), the transmitter allows control systems to immediately detect open-circuit or short-circuit faults.
• Environmental Resilience: Housed in an IP65-rated enclosure with a DIN-plug (EN 175301-803-A) electrical connection, the unit is protected against dust and low-pressure water jets, ensuring longevity in washdown environments.

Technical Specifications

FAQs

Why is a "flush diaphragm" necessary for my application? A flush diaphragm is critical in applications involving viscous fluids (like syrups, pastes, or slurries) or hygienic processes. Because the diaphragm is exposed directly to the main flow, it prevents the sensing port from clogging, which would otherwise lead to "ghost" readings or sensor failure in standard transmitters.

Can this transmitter be used in hazardous areas? The unit carries ATEX approval, which pertains to its safety characteristics in potentially explosive atmospheres. However, you must verify that the specific hazardous zone classification matches the ATEX rating of the device before installation.

Does the transmitter require periodic calibration? No, the 060G3203 does not support field adjustment of zero or span. It is factory-calibrated to ensure long-term stability. If the device falls out of its accuracy specification over many years of use, it should be replaced or returned to the factory for recalibration.

Engineering Guidelines and Best Practices

• Installation Torque: The 27 mm hexagonal nut is designed for tightening. Use a proper wrench and ensure the hygienic or standard sealing gasket is seated correctly to avoid leaks or pressure-induced measurement errors.
• Media Temperature: While the ambient rating is up to 85°C, the compensated temperature range is 0 - 80°C. For processes exceeding these temperatures, consider using a cooling extension or a "pigtail" siphon to protect the transmitter's internal electronics from excessive heat conduction.
• Cleaning Protocols: In hygienic applications, ensure that your CIP (Clean-in-Place) or SIP (Sterilize-in-Place) chemicals are compatible with the stainless steel diaphragm material (typically 316L) to prevent surface pitting.
