The MTL series is a product line of magnetostrictive displacement sensors specially designed by Miran Technology for built-in applications in high-pressure oil cylinders. With its non-contact measurement, high precision, and high-pressure resistance features, it has been maturely applied in hydraulic systems across multiple industrial fields.

Core technical features of the MTL4C series

The MTL4C is a built-in magnetostrictive displacement sensor for Miran universal cylinders, featuring the following core advantages:

High-precision measurement: Based on the magnetostrictive principle, the accuracy can reach the micrometer level, with high resolution and fast dynamic response, making it suitable for real-time closed-loop control

Non-contact design: The movable magnetic ring has no mechanical contact with the sensing rod, avoiding wear and tear, ensuring a long service life and eliminating the need for recalibration

High-pressure resistance capacity: The measuring rod can be directly built into the hydraulic cylinder, with a pressure resistance of up to 35MPa, and some models can reach up to 64MPa

Multiple output signals: Supports 4-20mA, 0-10V, RS485, CANopen and other output methods, compatible with mainstream control systems

Long stroke coverage: The effective stroke supports 30mm to 5000mm**, and the buffer stroke at both ends can be customized

LED status indication: The head of the electronic warehouse is equipped with an LED display light, which can directly reflect the working status of the product

Typical application cases

Case One: Closed-loop control of piston position in Hydraulic cylinders

In the electro-hydraulic servo control system, the MTL4C sensor measuring rod is internally installed through the reserved installation holes in the hydraulic cylinder. The magnetic ring is directly fixed on the piston of the hydraulic cylinder with screws, and real-time displacement measurement and position preset feedback are achieved along with the reciprocating motion of the piston.

The sensor feeds back the piston position signal to the PLC or servo controller to form a closed-loop control system, which is widely used in the displacement and stroke measurement of oil cylinders, hydraulic cylinders and pneumatic cylinders in fields such as construction machinery, industrial automation and hydraulic systems.

Case Two: Displacement Measurement of HydraulicCylinders for Gate Opening in Water Conservancy Projects

The Miran MTL series has been successfully applied to the displacement measurement of hydraulic cylinders for gate opening in water conservancy projects, with an effective stroke of 4.65 meters. The sensor is built into the hydraulic cylinder of the gate to monitor the opening displacement of the gate in real time, ensuring precise control of the operation of water conservancy facilities.

Case Three: Heavy Equipment and Special Oil cylinders Built-in

Based on the core technology of "built-in magnetostrictive displacement sensor", the MTL series sensors are installed inside the piston rod to precisely detect the displacement of the piston rod movement, and are used for quality control of special equipment such as hydraulic boosters.

The MTL4C sensor is also widely used in the measurement of cylinder displacement in fields such as injection molding machines, aerospace, metallurgy and heavy equipment, ships and Marine engineering.
