Product Overview

The Danfoss MBS 3000 series stands as the definitive benchmark for compact pressure measurement in the global industrial sector. Designed for versatility and long-term stability, this transmitter facilitates precise monitoring in high-pressure hydraulic systems, air compressors, and water treatment plants. The MBS 3000 utilizes a piezo-resistive sensing element that provides superior vibration stability and EMI/RFI resistance, ensuring that critical process data remains accurate even in electrically noisy environments. Its robust stainless steel construction resists mechanical fatigue, while the laser-calibrated electronics deliver a consistent 4-20mA output. Whether integrated into a machine tool's hydraulic loop or a localized pumping station, the MBS 3000 provides the reliable feedback loop necessary to prevent overpressure events and optimize system energy consumption.

Core Technical Advantages

Superior Vibration and Shock Stability

The internal sensor mounting utilizes a specialized dampening architecture that protects the silicon element from high-frequency vibrations and mechanical shocks common in heavy machinery. This design ensures that the transmitter maintains its ±0.5% FS accuracy over years of continuous service, even when mounted directly onto pulsating pump discharge lines.

Advanced Electromagnetic Compatibility

Danfoss engineers the MBS 3000 to exceed standard CE requirements for electromagnetic interference. This enhanced protection prevents signal drift or "ghosting" when the sensor operates in close proximity to high-power variable frequency drives (VFDs) or large electrical contactors, ensuring your PLC receives a clean, reliable data stream.

Laser-Welded Stainless Steel Housing

The AISI 316L stainless steel enclosure features complete laser welding, eliminating the need for internal O-rings that could degrade over time. This hermetic seal protects the internal electronics from moisture ingress and atmospheric corrosion, making the MBS 3000 suitable for outdoor installations and wash-down environments.

Engineering Installation Guide

Mechanical Mounting and Sealing

When threading the G 1/4 A connection into your manifold, utilize a proper copper or bonded seal washer to ensure a leak-proof interface. Tighten the transmitter to the manufacturer-specified torque (typically 30-35 Nm) using a 27mm wrench on the hexagonal base; never apply torque by gripping the transmitter body or electrical connector.

Wiring and Loop Integrity

The two-wire 4-20mA circuit requires a shielded, twisted-pair cable for distances exceeding 10 meters. Terminate the shield at the control cabinet's ground bar to drain induced noise. The DIN 43650-A plug features marked terminals; verify that Terminal 1 (Positive) and Terminal 2 (Output/Negative) are wired correctly before energizing the loop.

Thermal Isolation

In applications where media temperatures exceed 85°C (such as steam lines), we recommend installing a capillary tube or a cooling siphon between the process and the transmitter. This simple addition protects the sensitive piezo-resistive element from thermal damage, ensuring the sensor operates within its calibrated temperature window.

Engineering Advantages

The MBS 3000 excels in high-reliability industrial loops where sensor failure results in costly downtime. Its compact form factor allows for high-density installation in hydraulic power units where space is at a premium. Unlike lower-tier sensors that suffer from zero-point drift, the MBS 3000 maintains exceptional long-term stability, reducing the need for frequent field recalibration. The 060G1133 and other variants within the 3000 series are fully compatible with modern PLC analog input cards, providing a "plug-and-play" experience for system integrators. By standardizing on this platform, procurement managers secure a component with a proven MTBF (Mean Time Between Failure) that satisfies the most stringent requirements of global OEM equipment manufacturers.

Technical FAQs

Q1: What is the pressure range of the 060G1133 model?

A1: The 060G1133 is specifically calibrated for a range of 0 to 10 bar (Gauge pressure). If you require different ranges (e.g., 0-25 bar or 0-400 bar), please specify the required range when ordering.

Q2: Can I use this transmitter with aggressive chemicals?

A2: The wetted parts are made of AISI 316L stainless steel. While this is highly resistant to water, air, and oil, always verify the compatibility of 316L with your specific chemical media before installation.

Q3: Is the electrical DIN plug included with the transmitter?

A3: Yes, we supply the MBS 3000 complete with the matching DIN 43650-A electrical connector and the necessary gasket to ensure an IP65 seal upon installation.

Q4: How do I troubleshoot a 4mA signal when the system is under pressure?

A4: First, check for loop power and verify that the supply voltage is between 9-32V DC. If power is present, inspect the pressure port for blockages or debris that may be preventing the media from reaching the sensing diaphragm.
