Mounting and Installation Guidelines (continued)
2.2.1 Installation of Flush-Mounted Sensing Elements
Material Backed-Up Above
Sensing Element
(No Flow)
Mount the sensing element as to avoid enhancing
electrostatic discharge from the process medium, as is good
practice with any thermowell, displacer, or sampler. This
includes correct bonding to the tank or silo wall.
If installation area is rated explosion-proof and requires
conduit seal fittings, they should be used in accordance with
company standards and local codes.
Mounting the sensing element inside a pipe is not
recommended.
Do not mount a Cote-Shield sensing element through a
nozzle that exceeds the length of first insulator.
Ensure there are no obstructions or agitator blades to
interfere with sensing element.
Rigid sensing elements can be mounted either vertically or
horizontally.
These instructions apply to all flush on/off sensing elements,
models 700-0207-001, 700-0207-002, 700-0207-003, 700-0207-
004, 700-0207-006. These systems will sense presence of
material (no flow or plugged chute) and absence of material
(flow or empty chute) at the sensing element. The Flush
Sensing Element will ignore free falling material.
Sensing Element at the Top of a Chute.
• The flush sensing element should be mounted In
The Flow Stream. These sensing elements are
designed and built to withstand the impact of coal,
rock, wood, chips, etc. This location is important
to prevent excessive build up of material on the
face of the sensing element.
• Excessive build up, typically consisting of wet and/
or sticky fines, can occur if the sensing element is
protected from falling material.
Sensing Element in an angle chute.
• Do not mount on the top or bottom.
• Best mounted on either side
7
Sensing Element at the Bottom
• Mount on any side.
• Low-Level sensors can be used to detect
a plug or to insure that a seal is present
(chute is full at this point).
