MV-3 Intelligent Speed Digital Display InstrumentDetailed product description：

The MV-3 intelligent speed digital display instrument is a new generation of intelligent speed digital display instrument that uses a new single-chip microprocessor as the main chip. It includes most of the functions of speed digital display instruments, with five digit data display and one digit function display, capable of measuring frequency and speed, and has functions such as relay alarm output, 4-20mA analog output, and RS232C interface. This display instrument is flexible and reliable, suitable for measuring and controlling the speed and frequency of power plant steam turbines, industrial steam turbines, and other types of speeds and frequencies.

The MV-3 intelligent speed digital display instrument not only has and improves the functions of traditional speed meters, but also expands the "black box" function. There are mainly the following characteristics:
1. High speed sampling of data, with sampling time adjustable between 0.1 and 2.0 seconds;
2. Recall the speed of the accident process and retrieve 3600 recorded data;
3. Adopting password locking function, operators who master the password can modify parameters and refuse illegal operations;
4. Can interface with PC to output serial data.
The full range of 5.4-20mA analog output can be set through panel keys, making the instrument a truly intelligent digital instrument.
