Signet 2250 Hydrostatic Level Sensor

1. Description

2. Speciﬁ cations

The Signet 2250 Hydrostatic Level Sensor uses a gauge pressure sensor to calculate the level of ﬂ uid in a tank.

Gauge pressure sensors measure the difference in pressure between the process on one side of a diaphragm and the atmospheric

pressure on the opposite side of the diaphragm. A tiny capillary tube running from inside the sensor body and

up the length of the cable provides the reference to atmospheric pressure.

Hydrostatic level measurement can be a simple and practical solution to those applications where the ﬂ uid

temperature is stable and constant.

IMPORTANT! This method of level measurement is not recommended if the ﬂ uid is subject to

temperature variations or any other variable that causes the density of the ﬂ uid to change.

The 2250 Hydrostatic Level Sensor has excellent chemical compatibility.

The wetted materials are PVDF, Ceramic and FPM.

Several different hardware mounting kits are available to accommodate every installation requirement.
