If it is the essential safety pressure gauge, it is necessary to fit with the safe bar to form the essential safety system as following:

The pressure transmitter has been debugged according to the order requirements, and the user does not need to make any further adjustment.If re brcalibration after long use, you can adjust the zero potentiometer and adjustment range potentiometer respectively.The lower limit of the pressure range corresponds to the 4mA, upper limit corresponding to 20mA. 

The transmitter has been debugged as the customer ’s request, no need to debug again.After long time of using, if needed, it can be debugged by adjust “Zero electric device ” and “Range electric device ”.The down limit of the range should be corresponding with 4mA ，and up limit will be with 20mA. 

Installation notes 

The 1. is installed directly on the measurement point (at any angle). 

2. tries to install a temperature gradient with small temperature fluctuations while avoiding strong vibration and shock. 

3. When measuring steam or other high temperature medium, be careful not to overlimit the operating temperature of the transmitter.Install the radiator or other cooling device connection when necessary. 

During 4. installation, the pressure stop 

valve shall be installed between the transmitter and the medium to repair and prevent the blocked pressure outlet and affect the measurement accuracy.Damper pressure buffer shall also be installed for large pressure fluctuation range.
