MBS 3000 (060G1106) Danfoss Compact Pressure Transmitter

Product Overview

The MBS 3000 (060G1106) is a compact, heavy-duty pressure transmitter designed for use in almost all industrial applications, even under severe environmental conditions. As a cornerstone of the Danfoss industrial sensor portfolio, the Danfoss 060G1106 (060G1106) provides a reliable 4–20 mA output signal proportional to the measured pressure. This model is specifically calibrated for a 0–60 bar gauge pressure range, making it an ideal choice for B2B applications in hydraulic systems, air compressors, and water treatment plants where precision, vibration stability, and electromagnetic compatibility (EMC) are essential requirements.

Technical Configuration

The MBS 3000-2811-1AB04 is engineered for long-term stability. It features a piezo-resistive silicon sensing element housed in a high-grade acid-resistant stainless steel enclosure (AISI 316L). The electrical interface is a standardized Plug Pg 9 (EN175301-803-A), ensuring easy installation and maintenance. The pressure connection is a G ¼ A thread according to EN 837 standards. To handle the rigors of industrial environments, the transmitter is highly resistant to cavitation, liquid hammer, and pressure peaks, ensuring a long service life even in systems with fluctuating hydraulic loads.

Technical FAQs

What does "Gauge (Relative)" pressure reference mean for the 060G1106?

Gauge pressure means the transmitter measures the pressure relative to the current atmospheric pressure. The sensor will output 4 mA when the system is open to the atmosphere and 20 mA when the system pressure reaches 60 bar above atmospheric levels.

Can this transmitter handle high-vibration environments?

Yes, the MBS 3000 series is specifically designed for industrial machinery. It is tested for vibration stability according to IEC 60068-2-6 and shock resistance according to IEC 60068-2-27, making it suitable for mounting directly on pumps and engines.

Is the output signal protected against wiring errors?

The transmitter includes polarity protection, meaning it will not be damaged if the positive and negative wires of the 4–20 mA loop are accidentally reversed during installation.

Engineering & Installation Guide

• Wiring for 4-20 mA Loop: The MBS 3000 uses a 2-wire configuration. Connect the positive supply to Pin 1 and the return signal to Pin 2 of the Pg 9 plug. Ensure the total loop resistance does not exceed the limit determined by your supply voltage ($R_{loop} \leq (V_{supply} - 9V) / 0.02A$).

• Pressure Port Sealing: When installing the G ¼ A connection, use a suitable bonded seal (Dowty washer) or copper gasket to ensure a leak-proof interface. Avoid using PTFE tape on parallel threads as it can lead to improper seating or debris entering the sensing orifice.

• Environmental Protection: To maintain the IP65 rating of the electrical connection, ensure the Pg 9 plug's gasket is correctly seated and the central screw is tightened. For outdoor installations, it is a best practice to point the cable entry downwards to prevent water from pooling at the connector interface.
