Danfoss 060G2420 MBS Series Flush Diaphragm Pressure Transmitter

Product Overview

The 060G2420 (060G2420) is a high-precision pressure transmitter engineered for industrial applications requiring a Flush Diaphragm interface. This design is critical for measuring the pressure of high-viscosity, crystallizing, or contaminated media in sectors such as food and beverage processing, wastewater treatment, and chemical manufacturing. With a low-pressure range of 0 to 0.6 bar, the 060G2420 delivers an industry-leading typical accuracy of 0.2% FS, ensuring tight process control and preventing costly material waste. Its ATEX approval permits safe operation in potentially explosive atmospheres, making it a reliable solution for monitoring tank levels or pipeline pressures in hazardous industrial zones.

Technical Configuration

The 060G2420 utilizes a piezoresistive sensing element protected by a robust flush-mounted diaphragm. This configuration prevents media build-up and clogging, which often plague standard pressure ports in "dirty" processes. The transmitter outputs a standard 4-20 mA analog signal, featuring a low clipping level of 3.6 mA and a high clipping level of 22.4 mA for advanced diagnostic capabilities. Encased in an IP65 rated housing with an EN 175301-803-A (DIN-plug) electrical connection, the device is designed for rapid installation and resistance to mechanical vibration. The internal electronics are temperature-compensated between 0 to 80 deg C to maintain signal integrity despite ambient thermal fluctuations.

Technical FAQs

Why is the flush diaphragm essential for this specific model?

The flush diaphragm eliminates the "pressure cavity" found in standard sensors. This prevents thick or particulate-heavy fluids (like pulp, sludge, or adhesives) from hardening inside the sensor port, which would otherwise lead to drift or total sensor failure.

Does the 060G2420 require a separate safety barrier for ATEX zones?

Yes. While this unit carries ATEX approval for hazardous areas, it must be installed in conjunction with a certified intrinsically safe barrier or zener barrier if the specific zone classification requires limited energy spark protection.

What is the significance of the 4 ms response time?

A 4 ms response time allows the transmitter to detect rapid pressure spikes or "water hammer" effects in pipelines. This high-speed feedback is vital for automated safety systems to trigger emergency shut-off valves and protect downstream equipment.

Engineering & Installation Guide

• Sealing and Torque: When installing the 41 mm HEX pressure connection, ensure the sealing gasket is compatible with the process media. Use a calibrated torque wrench to avoid over-tightening, which can distort the flush diaphragm and cause a zero-point shift.

• Cleaning Protocol: Because the diaphragm is exposed, never use sharp objects (like screwdrivers or wire brushes) to clean the sensor face. Use a soft cloth and a compatible solvent to prevent scratching the thin metallic membrane, which could compromise accuracy and corrosion resistance.

• Wiring for Noise Immunity: In environments with high electromagnetic interference (EMI)—such as near large VFDs or motors—use twisted-pair shielded cable for the 4-20 mA loop. The shield should be grounded at the PLC/Controller side only to prevent ground loops that could distort the 0.2% accuracy performance.
