The JM series of magnetostrictive linear position sensors are based on the magnetostrictive measurement principle. That combines high accuracy, large linear range, absolute position and features non-contact, high reliability and long duration. The extremely robust sensor is ideal for continuous monitoring and measurement systems, or for machine control involving hydraulic, pneumatic, electromechanical under harshest industrial conditions, such as oil stain, dust or high voltage.

Shanghai Utmost's JM magnetorstrictive linear position sensor and level sensor are manufactured by high performance material and auto calibration equipment. The JM series is a highly price-performanced product which has absorbed the advantages of similar products and reaches international criteria.
