Chongqing Chuanyi MS22PSB2D10B0060DMZ Magnetostrictive Level Gauge
MS22PSB2D10B0060DMZ
Engineered for ultimate reliability and high-accuracy fluid monitoring, the MS Series Magnetostrictive Liquid Level Transmitter delivers continuous, real-time measurements for total liquid level and interface positions in demanding industrial environments. Utilizing advanced magnetostrictive sensing technology, this versatile transmitter provides precise, non-contact signal processing with a measurement accuracy up to ±1mm, making it an ideal solution for critical process controls across chemical processing, oil and gas, power generation, and water treatment applications where long-term stability and explosion-proof durability are paramount.
The MS Series Magnetostrictive Liquid Level Transmitter represents a state-of-the-art solution designed for high-accuracy continuous measurement of liquid surfaces and oil-water interfaces across complex industrial processes. Operating on the proven principle of magnetostriction, the sensor generates electromagnetic pulses sent down a specialized waveguide wire enclosed within a protective non-magnetic probe. When this impulse interacts with the magnetic field created by the internal floats, a torsional stress wave is generated and travels back to the electronics housing.
By precisely calculating the microsecond time delay between the initial pulse and the returning strain wave, the transmitter accurately calculates float positions to deliver continuous 4–20mA and HART signals with exceptional repeatability and zero drift over extended operations. Built with versatile material options including 316L stainless steel, PFA coatings, titanium, and Hastelloy, the MS Series adapts seamlessly to highly corrosive media, cryogenic liquids down to -196°C, and severe thermal environments up to 450°C under high pressures up to 6.3 MPa.
Featuring both rigid rod configurations for compact vessels up to 4 meters and heavy-duty cable probes extending up to 20 meters, this instrument supports dual-float technology to simultaneously measure liquid level and interface positions within a single tank opening. Certified under rigorous PCEC intrinsic safety and flameproof standards with an IP67 rated enclosure, the transmitter delivers continuous operational safety across oil refineries, petrochemical plants, wastewater facilities, power plants, and food-grade hygienic processing vessels worldwide.
FAQ
Q1: Can the MS Series transmitter measure both total level and liquid-liquid interface simultaneously?
A1: Yes, the MS Series supports dual-float configurations, allowing a single transmitter to simultaneously measure both the total liquid surface level and the interface layer between two immiscible liquids (such as oil and water) within the same tank opening.
Q2: What is the maximum measurement length available for rigid and cable probes?
A2: The rigid rod probe option supports vessel depths up to 4 meters, while the flexible cable probe configuration is designed for deep storage tanks and silos, reaching maximum measuring lengths of up to 20 meters.
Q3: How do I select the proper wetted material for corrosive chemicals?
A3: Standard applications typically utilize 304 or 316L stainless steel. For aggressive acids, alkalis, or highly corrosive industrial chemicals, we offer specialized protective coatings like PFA and ECTFE, as well as high-grade corrosion-resistant alloys such as Titanium and Hastelloy.
Q4: Is this liquid level transmitter safe for installation in hazardous explosive areas?
A4: Absolutely. The MS Series features comprehensive PCEC explosion-proof certifications, including Intrinsically Safe (Ex ia IIC T5/T6 Ga), Flameproof (Ex db IIC T6 Gb), and Dust Flameproof (Ex tb IIIC T80°C Db) ratings for hazardous environments.
Q5: What process communication options are supported for system integration?
A5: The instrument offers a standard 4–20mA analog loop output with optional HART protocol communication, programmable LCD display units, and up to three SPDT relay switch outputs for seamless integration into PLC, DCS, or SCADA supervisory systems.
