Description
ACD-2K Pressure Controller is provided with alarm control function on the basis of ACD-201 Digital Pressure Gage functions, status display and alarm relay contacts output are provided, the upper and lower limit alarm points can be set, and return difference can be controlled, ACD-2K can also drive the relay output. Signal isolation design, without any interference, the standby lithium battery is built-in, which could work 5 to 8 years continuously, the acquisition pressure can be stabilized when the external power is broken off ( but the output signal is invalid); the advantages of pressure controller are high control accuracy, fast response speed, stable performance, small in size, convenient installation, etc., is the ideal electric-contact pressure gauge. The construction can be selected from radial direction type, axial direction type and panel mounting type.
