MBS1250 / 063G1857 Pressure Transmitter – 0–400 bar, 4–20 mA, Deutsch DT04, IP67, Genuine for LiuGong CLG920D/936D/948E Excavator (30B0506)
MBS1250 / 063G1857 – Genuine Pressure Transmitter for LiuGong Excavator (30B0506)
The MBS1250 / 063G1857 is a genuine Danfoss heavy-duty pressure transmitter engineered for the demanding hydraulic systems of LiuGong construction machinery. As a direct OEM replacement for part number 30B0506, it is purpose-built for excavator models CLG920D, CLG922D, CLG936D, and CLG948E, providing accurate and reliable pressure monitoring essential for machine control and protection.
Measurement Performance
This transmitter covers a pressure range of 0 to 400 bar and provides a standard 4–20 mA analog output, ensuring seamless integration with the excavator’s electronic control unit (ECU). It delivers a typical accuracy of ±0.5% FS, providing dependable data for hydraulic system diagnostics, load sensing, and pressure regulation. The response time is ≤ 1 ms, enabling the system to react instantly to pressure changes during dynamic excavator operations.
Overload and Burst Protection
For the 0–400 bar version, the transmitter withstands an overload pressure of 1200 bar and a burst pressure of 4000 bar, offering a substantial safety margin for high-pressure hydraulic circuits and occasional pressure spikes.
Integrated Pulse-Snubber for Severe Hydraulic Applications
The MBS 1250 series is distinguished by its integrated pulse-snubber, which effectively dampens destructive pressure peaks, cavitation, and liquid hammer effects. These conditions are common in excavator hydraulic systems during rapid valve closures, pump starts/stops, and sudden load changes. The pulse-snubber significantly extends sensor service life and maintains measurement stability.
Durable Construction for Mobile Machinery
The transmitter features a robust construction with a stainless steel housing and wetted parts, providing excellent corrosion resistance against hydraulic fluids and environmental exposure. It operates across a media temperature range of -40°C to +125°C, suitable for both cold-climate and high-temperature engine compartment installations.
Connectivity and Environmental Protection
The electrical interface is a Deutsch DT04 4-pin connector, ensuring a secure, vibration-resistant, and sealed wiring connection ideal for mobile equipment. The pressure connection is a G 1/4A external thread conforming to DIN 3852-E standards. With an IP67 protection rating, the transmitter is fully dust-tight and protected against temporary immersion in water.
High Vibration and EMC Stability
Designed for severe mobile hydraulic environments, the MBS1250 offers high vibration stability and enhanced EMC protection, ensuring stable signal output even in the presence of heavy electrical noise from motors, alternators, and other excavator systems.
CE Certified
The transmitter is CE marked, confirming compliance with applicable EU directives for electromagnetic compatibility and safety.
Choose the MBS1250 / 063G1857 for your LiuGong excavator hydraulic system — where genuine OEM quality, pulse protection, and long-term reliability are essential for maximum machine uptime.
