Description
The Delta
Controls Model 562 level transmitter consists of a potted electronic
module and a pressure sensing probe. The probe consists of a cable connected
sensor supported and protected by a S.S. body and supported by a rigid 3/4"
Sch 40 pipe. The electronics housing can be mounted directly on the probe head
or remotely for convenience or safety. The length of supporting pipe can be
supplied by Delta Controls or by the user.
Typical
Applications
When the Delta Controls
Model 562 is installed in a tank, sump, basin or other containment, the strain
gage sensor detects the pressure exerted on it by the water or other liquid
surrounding it. This pressure is linearly proportional to the height and density
of the liquid above the sensor. There are no cavities and the diaphragm is completely
open to the liquid being measured. The sensor cannot be plugged and rendered
inoperable by liquids with high solids contents. Waste liquids and slurries
are easily handled.
The top mounting feature
of the Model 562 makes it easy to use in concrete basins, sumps and other containments
where bottom or side mounting of a sensor would be difficult or impossible.
Compared to a capacitance probe transmitter, it requires neither reference ground
nor periodic cleaning and recalibration to function accurately and reliably.
The 562's probe can be mounted
using a wide range of NPT and flanged connections. It can also be supplied with
either a vertical wall or a horizontal ledge mounting bracket for support over
basins, open tanks, pits, and similar installations. The sensor is referenced
to atmospheric pressure through a vent tube. A desiccant filter or isolation
bladder prevents moisture condensation in the tube.
