NIHON KOSO CO.
Nihon Koso KGP5000 Smart Valve Positioner
Manufacturer: NIHON KOSO CO., LTD.
Model: KGP5000
Features
Large-screen LCD ＆ easy configuration by ‘Full autotune’
- Local user interface with large graphic LCD by itself enables performing all the operations such as setup, adjustment, status monitoring, execution of diagnostics, etc.
- The function of ‘full autotune’ can set automatically zero & span point and select optimal PID control parameters by automatic tuning.
Stable valve control using advanced control algorithm
- Advanced PID control selects suitable parameters according to deviation size, direction.
Preset values of PID parameters are provided suitable for linear or rotary actuators.
Diagnostics and alarm functions for maintenance cost reduction
- Online valve diagnostics enables the exchange from breakdown maintenance to preventive maintenance through status monitoring.
All-in-one design for inventory-related troublesome reduction
- Latest digital communication “HART7” compliant
Built-in position transmitter function
Applicable to both single and double acting actuator only through the switching between single and double mode on pilot relay
