Selection of damper

Use

Cavitation, hammer and pressure spikes may occur in air or liquid systems with varying flow rates. such as rapid closing of valves or starting and stopping of pumps.

These problems can occur at the inlet and outlet even at fairly low operating pressures.

medium conditions

In liquids containing particles, nozzle clogging may occur. Vertical mounting of the transmitter minimizes the risk of clogging because fluid flow is limited to the initial start-up phase, the volume at the rear of the nozzle is fixed, and the nozzle bore is relatively large (1.2 mm).

The viscosity of the medium has little effect on the response time. Even if the viscosity reaches 100 CST, the response time will not exceed 4 ms.

model selection

order alerts

1、Please pay attention to the compatibility between the tested medium and the contact part of the product when selecting.

2、The range is between 1~35kPa, which can be customized (range ≤6kPa, pressure sensor without oil filling is selected, and the measurement medium must be pure gas).

3、Range between 25~100MPa, the application site has super pressure shock, can be customized.
