SQY01 series speed digital display instrumentDetailed product description：

The SQY01 series digital display instrument is a new generation of intelligent digital display instrument that uses a new single-chip microprocessor as the main chip. This series includes most of the functions of digital display instruments, including frequency measurement, speed measurement, counting, and detection of various engineering electrical quantities. It also has functions such as relay alarm output, analog output, pulse output, and RS232C and RS485 interfaces. Widely applicable for measurement, control, and display in industries such as power, metallurgy, shipbuilding, machinery, textiles, and papermaking. The design of this series of products always puts the user's wishes first, ensuring the reliability, anti-interference and applicability of the products are fully guaranteed.

The SQY01 series is divided into two main series: T/D digital display instrument series and J counting display controller series. The basic performance of the two subsystems is as follows:
1. Power supply: 85-285V, 50/60Hz or DC 11-36V;
2. Digital display range: 0.0000 to 99999;
3. Detection range: Frequency input: 0.01-10kHz;
Voltage input: 0-1V (or 0-10V, adjustable range)
Current input: 0-10mA (or 4-20mA, adjustable range)
4. Basic error: speed ± 0.02%;
Count ± 1 word;
Analog quantity ± 0.5% FS;
5. Parameters can be set arbitrarily;
6. Products with RS232C and RS485 interfaces can be remotely configured and can also be equipped with smart terminals such as printers or computers.
7. Hole size: 150 × 75
8. Dimensions: 160 × 80 × 130

There are several other instruments available for selection that have different appearances but the same function:

Serial Number	model	Overall dimensions	aperture size
one	SQY01	160×80×130	150×75
two	SQY02	72×72×100	68×68
three	SQY03	96×48×110	92×45
four	SQY04	160×160×230	152×152
five	SQY05	48×48×90	45×45
six	SQY06	144×144×210	140×140
seven	SQY07	60×120×110	55×110
eight	SQY08	96×96×120	92×92
nine	SQY09	144×72×190	138×168

The SQY01 series is tailor-made according to user requirements, and has developed and extended hundreds of varieties and specifications of display measurement and control instruments. The XJP series, STM series, SKY series, SZC series, and MCS-II series are derivatives of the SQY01 series. In order to provide users with a basic understanding of our company's products and facilitate their selection, the following introduces several basic series of SQY01T/J products in the form of product spectra:

SQY01T series digital display instrument, mainly used for measuring frequency, flow rate, speed, and line speed, etc; The SQY01TD series digital display instrument mainly measures physical quantities such as voltage, current, speed, flow rate, pressure, temperature, angle, opening, and displacement related to voltage and current.  



SQY01J series counting display controller, mainly used for measuring and controlling length, height, depth, displacement, angle, and angular displacement, as well as flow accumulation and timing control;
