External Structure

 

 

SELECTION OF DAMPER

APPLICATION:
• Cavitation, liquid hammer and pressure spikes can occur in air or liquid systems with varying flow rates. Examples include quick closing of valves or starting and stopping of pumps.
• These problems can occur at the inlet and outlet, even at fairly low operating pressures.

 

MEDIA CONDITION:

• In liquids containing particles, clogging of the nozzle may occur. Mounting the transmitter vertically minimizes the risk of clogging, as the flow of fluid is limited to the initial start-up, while the volume the nozzle's aperture is relatively large (1.2mm). 
• The effect of medium viscosity on response time is small. Even if the viscosity reaches 100 CST, the response time will not exceed 4ms.
 

Thread Interface

Range Selection

NOTE: 1: G gauge pressure, A absolute pressure, S seal pressure.
            2: Use a non-oil-filled pressure sensor. The measurement medium must be pure gas.
