Problems solved by technology

[0003] The current sensors generally only use 5V power supply, which cannot be used in special working environments and on-site special power supply occasions, such as 20V power supply occasions, so the application area is narrow, so it is necessary to propose a wide power supply displacement measurement device that can meet special operations. On-site or matching system needs

Abstract

The invention relates to a wide power supply linear encoder used for a magnetic grating sensor. The wide power supply linear encoder comprises a microprocessor connected with an inductor, a TTL (transistor-transistor logic) output circuit, an input circuit of a power supply module separately, and also comprises a wide power supply module connected with the power supply module. The wide power supply module is used for transforming a voltage into a low voltage, and then transforming the low voltage into a voltage suitable for a sensor via the power supply module. The wide power supply linear encoder of the invention enables the application range and the use occasion to be expanded, can be applied to the special work environment, and realizes the characteristics of small power consumption and high precision.

Description

technical field [0001] The invention relates to the technical field of magnetic grid sensors, in particular to a wide power linear encoder for magnetic grid sensors. Background technique [0002] At present, in the field of measurement technology, there are already ball grid sensors, grating sensors, steel grid sensors and magnetic grid sensors. The magnetic grating displacement sensor is a displacement sensor that uses the magnetic interaction between the magnetic grating and the magnetic head for measurement. It is a new type of digital sensor. When needed, the original magnetic signal (magnetic grid) can be erased and re-recorded. Compared with other sensors, it has lower cost, higher precision, and is easy to install and Advantages of using. The magnetic grating sensor measures the displacement by sensing the distance between the N pole and the S pole on the magnetic strip, and converts the measured data into displacement for display. [0003] The current sensors gene...
