MBS1250 / 063G1802 Pressure Transmitter – 0–400 bar, 4–20 mA, AMP SuperSeal 3-Pin, G 1/4A, IP67, with Integrated Pulse-Snubber
MBS1250 / 063G1802 – Heavy-Duty Pressure Transmitter for Demanding Hydraulic Applications
The MBS1250 / 063G1802 is a high-performance pressure transmitter from the Danfoss MBS 1250 series, specifically engineered for continuous pressure monitoring in severe hydraulic environments and mobile OEM applications. With a full-scale measurement range of 0 to 400 bar (0–5801.51 psi) and a standard 4–20 mA current output, it provides dependable data for closed-loop control, load sensing, and hydraulic system protection.
Measurement Performance
The transmitter offers a typical accuracy of ±0.5% FS, delivering reliable measurement data for critical hydraulic functions. With a maximum response time of ≤ 1 ms, it captures transient pressure events instantly, supporting real-time control and safety interventions. The unit operates on a supply voltage of DC 8–30 V and withstands an overload pressure of 1200 bar and a burst pressure of 4000 bar, offering an exceptional safety margin for high-pressure hydraulic circuits.
Integrated Pulse-Snubber for Dynamic Protection
The MBS 1250 series is distinguished by its integrated pulse-snubber, which effectively dampens destructive pressure spikes, cavitation, and hydraulic hammer effects. These conditions are common in mobile hydraulic systems during rapid valve actuation, pump start/stop cycles, and sudden load changes. The pulse-snubber significantly extends sensor service life and maintains measurement stability under pulsating flow conditions.
Durable Construction for Harsh Environments
The transmitter features 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 -20°C to +125°C, suitable for both cold-climate and high-temperature engine compartment installations.
Connectivity and Environmental Protection
The electrical interface is an AMP SuperSeal 3-pin connector (Series 1.5), ensuring a secure, vibration-resistant, and sealed wiring connection ideal for mobile equipment and industrial machinery. 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.
Certifications
The transmitter carries CE and UL Recognized approvals, and is compliant with EU RoHS requirements.
Compatibility
This transmitter is compatible with a wide range of construction machinery and hydraulic systems, including excavators and other heavy equipment. It is commonly listed as compatible with LiuGong and similar construction machinery spare parts.
Quality Assurance
This product is supplied as 100% brand-new, backed by a 1-year warranty. Manufactured in Zhejiang, China, with delivery typically within 5–7 working days.
