JCD-900-type diesel manual fixed screw compressor controller
I. Overview
JCD-900MC-type diesel screw air compressor dynamic controller (hereinafter referred to as
controller) is a high-performance single-chip micro-computer controlled automatic diesel air compressor
dynamic monitoring system, using the latest type of MCU, combined with advanced control technology , can
accurately detect and display the engine speed, oil pressure, water temperature, tank level, the air compressor
exhaust pressure, exhaust temperature, and according to set parameters for the monitoring of the test, issue
the appropriate control signals, and through sound, light signals the alarm.
