MBS3050 Danfoss Pressure Transmitter IP65

Model Number	MBS3050

Product Description

Product Overview

The Danfoss MBS 3050 is a compact heavy-duty pressure transmitter designed for industrial and hydraulic pressure measurement. It should not be classified as a hydraulic control valve.

Its defining feature compared with the MBS 3000 is an integrated pulse-snubber, which improves resistance to cavitation, liquid hammer and pressure peaks commonly found in demanding hydraulic systems. Danfoss specifies the MBS 3050 family with multiple measuring ranges from 0–1 to 0–600 bar, multiple output options and a broad selection of pressure and electrical connections.

The exact Danfoss part numbers supplied in the original title include:

060G1152 — 0–160 bar
060G1151 — 0–100 bar
060G1154 — 0–400 bar
060G1409 — 0–25 bar
060G1415 — 0–16 bar

All five are individually identified by Danfoss as MBS 3050 pressure transmitters with 4–20 mA output, 9–32 V DC supply, G1/4 pressure connection, Pg9 electrical connection and IP65 protection, while the measuring range and overload pressure differ by part number.

The engineering signal chain is:

Hydraulic Pressure → MBS 3050 → 4–20 mA → PLC/Controller → Hydraulic Control System

This makes the transmitter suitable for pressure feedback, monitoring, alarms and closed-loop industrial hydraulic control.

Related Danfoss Models

MBS 3000

The MBS 3000 is the general compact pressure-transmitter platform without the integrated pulse-snubber found on the MBS 3050. MBS 3050 is the more appropriate family where cavitation, liquid hammer and pressure peaks are significant design concerns.

MBS 2150

The MBS 2150 is a high-temperature marine pressure-transmitter platform with ratiometric output and pulse-snubber technology. Danfoss documents measuring ranges from 0–1 to 0–600 bar, operation for severe maritime environments, AISI 316L construction and applicable temperature capability up to 125°C.

MBS 2250

The MBS 2250 is a heavy-duty high-temperature pressure transmitter designed for severe industrial and hydraulic environments. Danfoss specifies a ratiometric 10–90% output, integrated pulse-snubber, AISI 316L construction, 0–600 bar family coverage and sensor temperatures up to 125°C under applicable configurations.

Key Technical Advantages

Integrated Pulse-Snubber

The integrated pulse-snubber is the primary technical distinction of the MBS 3050. Danfoss specifically positions it for systems exposed to cavitation, liquid hammer and pressure peaks.

AISI 316L Stainless-Steel Construction

Danfoss specifies AISI 316L for both the housing and wetted components, providing a robust corrosion-resistant material system for demanding industrial and hydraulic environments.

Fast Pressure Response

The standard MBS 3000/3050 documentation specifies <4 ms response for liquids with viscosity below 100 cSt, supporting pressure feedback in fast-changing hydraulic circuits.

Stable Measurement Performance

The family specification is:

Typical accuracy: ±0.5% FS
Maximum accuracy: ±1.0% FS
Non-linearity: ±0.2% FS
Hysteresis/repeatability: ±0.1% FS

These characteristics make the transmitter suitable for monitoring as well as feedback applications.

Wide Measuring-Range Platform

The MBS 3050 family covers measuring ranges from 0–1 to 0–600 bar, while the exact part numbers supplied here cover 0–16, 0–25, 0–100, 0–160 and 0–400 bar.

IP65 Protection

The five listed part numbers are individually documented by Danfoss with IP65 enclosure protection, making them appropriate for many dusty, splash-prone industrial environments.

Industrial 4–20 mA Interface

The listed 060G variants provide 4–20 mA output with 9–32 V DC supply, fitting conventional PLC, DAQ and industrial analog-input architectures.

Long Pressure-Cycle Durability

Danfoss specifies >10 × 10⁶ pressure cycles durability for the MBS 3000/3050 family, supporting long-term use in cyclic hydraulic applications.

Application Areas

Typical applications include:

Hydraulic power units
Industrial hydraulic systems
Hydraulic pump stations
Hydraulic presses
Injection molding machinery
Mobile hydraulic equipment
Construction machinery
Marine hydraulic systems
Process machinery
Industrial automation
Hydraulic pressure monitoring
PLC-based hydraulic control
Pressure alarms and interlocks
Closed-loop pressure feedback

The five listed 060G variants should be selected according to the actual pressure measurement point rather than treated as interchangeable versions, because their measuring ranges and overload characteristics differ.

Expert Maintenance Tips

Select the Measuring Range Correctly

The listed versions span:

060G1415 → 0–16 bar
060G1409 → 0–25 bar
060G1151 → 0–100 bar
060G1152 → 0–160 bar
060G1154 → 0–400 bar

Avoid selecting a range that is unnecessarily high for the actual pressure point because a large full-scale range reduces the useful measurement span for a low-pressure application.

Distinguish Measuring Range From Overload Pressure

For 060G1154:

Measuring range: 0–400 bar
Static overload: 600 bar

The overload value is an abnormal-load capability and must not be interpreted as a continuous operating-pressure rating.

Install With the Appropriate Orientation

Danfoss warns that particles can clog the nozzle in contaminated liquids. For pulse-snubber configurations, an upright installation position can reduce the risk of clogging by limiting nozzle flow mainly to the start-up period.

Maintain Hydraulic Cleanliness

During installation and service:

Flush the pressure line
Clean the pressure port
Prevent seal debris from entering the port
Check filtration
Keep welding debris and metallic particles away from the sensing passage

Avoid Unnecessary Direct Shock Exposure

Although the MBS 3050 is specifically designed to tolerate pressure peaks and liquid hammer better than a standard non-snubber transmitter, installation should still avoid placing the sensor directly at the strongest pump pulsation point whenever the hydraulic layout allows a better measurement location.

Verify the 4–20 mA Wiring

For the listed 060G variants:

Pin 1 → + Supply

Pin 2 → Common

The transmitter provides a 4–20 mA signal. Verify the actual connector, PLC input resistance and supply voltage before commissioning.

Maintain Connector Sealing for IP65

The specified IP rating depends on the applicable electrical connection configuration and mating connector. Make sure the connector is correctly seated and sealed to maintain the intended environmental protection.

Use a High-Temperature Variant When Required

Where media or ambient temperature approaches or exceeds the standard MBS 3050 operating range, verify whether an MBS 2150 or MBS 2250 high-temperature configuration is more appropriate. Danfoss provides these dedicated variants for severe and high-temperature applications.

Verify the Complete Part Number Before Replacement

Do not order simply by “MBS 3050 G1/4.” Confirm:

Part Number + Measuring Range + Output + Pressure Connection + Electrical Connection

This is particularly important for 060G1151, 060G1152, 060G1154, 060G1409 and 060G1415, because their measuring ranges are different.

Apply 100% Simulated Working-Condition Testing

For replacement MBS 3050 units, the most meaningful validation is a dynamic hydraulic test:

Pressure Source → Hydraulic Pulsation → MBS 3050 → 4–20 mA → Data Acquisition

Recommended checks include:

Zero output
Full-scale output
4–20 mA linearity
Response time
Pressure cycling
Pulse response
Leakage
Connector sealing
Temperature drift
Long-duration stability

This is particularly valuable for an in-place replacement product because MBS 3050 is designed to operate under dynamic hydraulic pressure conditions rather than only at static bench pressure.
