Physical Installation
1)
The LS2100 is installed into the vessel wall using a ¾” NPT process connection. This can be either a threaded
coupling or a tapped entry such as a flange.
2)
The insulator should always extend at least 2” through the vessel wall.
3)
Always check for physical room around the location you have chosen to allow for installation. Allow 3.75” turning
radius to screw the probe in and clearance above for the length of the probe.
4)
CAUTION:
Always take the necessary safety precautions when cutting or welding in the coupling for the LS2100.
a)
Tag and lock out the electrical power to the equipment that services the vessels.
b)
Check liquid or dry powders that create a gas in the vessel for oxygen as well as the explosion factor.
(All dust will explode.)
c)
Vessels that are cross vented have to be isolated.
5)
Screw the LS2100 into the connection provided. In dry material applications, no sealant on threads is required. On
liquid, teflon or a good pipe thread sealant may be used.
6)
The LS2100 has a ¾” conduit entry. When wiring these units, conform to the National Electrical Code and any
other city or company codes.
7)
Always install the electrical connection into the ¾” conduit entry on the LS2100 so water will not follow the
connection routing into the threads of the conduit hub. To guarantee that condensation and water will stay outside
the unit, install an EYSM unilet before each LS2100 and fill with explosion proof sealing cement.
