060G5539 Danfoss MBS 3000 Industrial Pressure Transmitter

Product Overview

The 060G5539 (060G5539) is a compact, heavy-duty MBS 3000 series pressure transmitter engineered for use in almost all industrial applications. Designed for high-pressure hydraulic systems and industrial machinery, it converts a 0 - 400 bar measuring range into a standard 4 - 20 mA output signal. The MBS 3000-3611-1GB04 is built to withstand harsh environmental conditions, featuring excellent vibration stability and a high degree of EMI protection. Its robust stainless steel construction and acid-resistant housing make it an ideal choice for power plants, water treatment facilities, and mobile hydraulic equipment where long-term reliability and precision are critical for operational safety.

Suffix Breakdown

The model code MBS 3000-3611-1GB04 specifies the precise hardware configuration for this industrial sensor:

Technical Specifications

Technical FAQs

How do I wire the MBS 3000 for a 2-wire control loop?

The 060G5539 utilizes a standard 2-wire configuration. Connect the positive supply voltage (+Vcc) to Pin 1 and the signal return (Output/Ground) to Pin 2 of the EN 175301-803-A plug. Pin 3 is usually not used, and the earth terminal is for shield/grounding.

What is the benefit of the DIN 3852-E-G 1/4 (GB04) connection?

The GB04 connection features a G 1/4 thread with a recessed sealing face that accommodates a soft gasket (typically NBR or Viton). This provides a superior leak-proof seal compared to metal-to-metal tapered threads, especially in high-vibration hydraulic systems.

Is this transmitter suitable for high-pressure spikes?

While the 060G5539 is rated for 400 bar with a 600 bar static overload capacity, rapid hydraulic shocks can cause damage. For systems with severe water hammer or cavitation, the use of a Danfoss MBS series with an integrated pulse snubber (such as the MBS 3050) is recommended.

Engineering & Installation Guide

Mounting and Sealing: When installing the G 1/4 DIN 3852-E connection, ensure the mating port is clean and free of burrs. Tighten the transmitter to the recommended torque of 30 Nm. Over-tightening can deform the integrated gasket and lead to leaks or internal sensing element stress.

Signal Integrity and Grounding: In environments with high electromagnetic interference—such as near VFDs or large motors—use shielded twisted-pair cable for the 4-20 mA loop. The shield should be grounded at the controller side only to prevent ground loops. Ensure the DIN plug gasket is properly seated to maintain the IP65 protection rating.

Thermal Management: If the medium temperature exceeds 85 deg C, use a siphon or capillary tube to isolate the transmitter from the heat source. For every 10 cm of uninsulated capillary tube, the medium temperature will drop significantly, protecting the internal electronics of the MBS 3000 from thermal degradation.
