SWP-LED series PID (or a given valve position control apparatus (/PID) or a given valve) light display control instrument for measuring system of high precision control in need, can replace the amplifier directly drive the implementation of institutions (such as valve etc.).
SWP-LED series PID self-tuning control instrument /PID bargraph display control instrument in digital instrument and analog instruments in one, can be displayed to control the temperature, pressure, liquid level, velocity measurement signal quantity (high brightness LED digital display) and analog display (column display), that makes the measurement more clear intuitively, can choose a double light column display.
First, the main features
1, through a simple and quick parameter settings, can adapt to a variety of index number, to further improve the instrument's multi-purpose and reliability.
2, PID parameters self-tuning.
3, at the same time input, display measurement signal and valve position feedback signal. Are with analog control output (volume control switch output relay forward and reverse control) and an analog quantity transmitting output, suitable for all kinds of measurement control field.
4, automatically follow the given value of the external (or valve position feedback value) to control the output (analog control output or relay forward, reverse control output). Automatic / manual disturbance free switching. Manual switch to automatic, using the approximation method integrating, and switch with a limiting function, to achieve smooth switching of manual / automatic.
Two, special technical parameters control output PWM output, SCR trigger output, solid state relay output, voltage / current output settings / display accuracy +0.5% FS+1 digit max. The set value, value and display, no relative error ratio in the range of 0.0%-100.0% (unit: 0.1%) integral (reset) time 0-9999s (unit: 1s) differential (ratio) 0-9999s (unit: 1s) control cycle 1-250s (unit: 1s) sampling period 0.5s
