060G1109 Danfoss MBS 3000 Pressure Transmitter

Product Overview

The 060G1109 (060G1109) is a heavy-duty Danfoss MBS 3000 series pressure transmitter engineered for precision measurement in demanding industrial environments. Designed specifically for hydraulic applications, boiler systems, and water treatment plants, this compact sensor converts mechanical pressure into a stable 4-20 mA analog signal. By utilizing advanced piezo-resistive technology and high-grade stainless steel construction, the 060G1109 ensures long-term stability and EMI/RFI immunity. In critical sectors like oil refining and power generation, this transmitter plays a vital role in real-time pressure monitoring, effectively preventing equipment overpressure and reducing unscheduled downtime caused by sensor fatigue or signal drift.

Technical Specifications

Technical FAQs

How does the MBS 3000 handle pressure peaks in hydraulic systems?

The 060G1109 features a robust design that provides excellent vibration stability and high overpressure capability. For systems with extreme cavitation or liquid hammer, it is recommended to install a Danfoss pulse snubber to protect the sensing element.

What is the significance of the Gauge (relative) pressure reference?

A gauge pressure transmitter measures pressure relative to the atmospheric pressure at the installation site. This ensures that the 060G1109 reads zero bar when the system is vented to the atmosphere, regardless of altitude changes.

Is the 060G1109 compatible with corrosive media?

The wetted parts are manufactured from high-quality stainless steel (AISI 316L). While compatible with most hydraulic oils and non-aggressive gases, users must verify chemical compatibility if using the device with highly acidic or alkaline fluids.

Engineering & Installation Guide

Mounting and Sealing Integrity:

When installing the G 1/4 A pressure connection, ensure the use of a proper copper or bonded seal washer compliant with EN 837. Apply a maximum torque of 30 Nm to prevent stripping the threads or damaging the internal sensor housing. Always mount the transmitter in a position that prevents moisture accumulation within the electrical connector.

Electrical Interference Mitigation:

To maintain signal integrity in high-noise environments (near VFDs or large motors), use shielded twisted-pair cabling for the 4-20 mA loop. The shield should be grounded at the controller end only to avoid ground loops. Ensure the Pg 9 plug is fully seated and the retaining screw is tightened to maintain the IP65 ingress protection rating.
