tk-pid auto-tuning / light cross display controller（controlled by outside or valve position）applies to the need for high precision measuring and control system, and can replace the amplifier to directly drive the implementation institutions (such as the valve position, etc.).
tk-pid auto-tuning / light cross display controller（controlled by outside or valve position）combines digital meter and analog meter in one instrument. it can take digital display control (high-brightness led digital display) and relative analog display (light cross) to the measuring signal of temperature, pressure, level and speed, so that the display of the value can be clearer and more intuitive and it can also choose two-column display mode.
features
1. through a simple and quick parameter setting, it can fit a variety of sub-degree numbers, to further improve the instrument's versatility and reliability.
2. pid parameter self-tuning
3. input and display the measurement signal and valve position feedback signal at the same time. it can be with analog control output(switch control output, relay forward and reverse control), and analog transmission output, applicable for a variety of measuring and control applications.
4. control output (analog control output or relay forward and reverse control output) automatically based on the external setting points (or the feedback value of valve position). it can be switched manually or automatically without interference. when manual is switched to automatic, approximation method will be used here with limited range, to achieve manual / automatic smoothly switching.
