SQY03T125-4 Speed digital display instrumentDetailed product description：

I. Overview
SQY03T125-4DC speed digital display instrument is a typical product of SQY03T series speed digital display instrument; Featuring a 5-digit digital display and 4-20mA current output; It can be matched with magneto electric sensors and NPN-OC switches. In addition to detecting general speed, linear velocity, and flow rate, it can also measure ultra-low and ultra-high speeds. It is an intelligent speed display control instrument.
SQY03T125-4DC intelligent speedometer has 10 sets of user parameters, which can be queried/modified by the operation keys on the panel or computer. The confirmed parameters can be saved for a long time. Satisfying various engineering needs, it has become a truly intelligent instrument.
The manufacturer has combined more than 20 years of professional design and manufacturing experience, applied new design concepts and electronic technologies, and optimized module combinations to cover various specifications of the original XJP-48T series products, and has made new expansions and extensions in composite functions. This not only improves the quality control level of standardized production, but also facilitates user selection. At present, it has been widely used in industries such as shipbuilding, metallurgy, energy, chemical engineering, electronics, machinery, and automobile manufacturing.
