and 316L S.S. materials in various
lengths and diameters, including
hinged models, to accommodate a
wide range of control applications.
The 1001 has a smaller case than the
1001A or 1001XL and has a knurled
knob screw type closure. The 1001A
a
nd 1001XL have lever latch door

Before disassembly or maintenance, all
pressures in this device must be relieved.
Failure to relieve pressures may result in
personal injury or device damage. The
resulting uncontrolled venting or spilling
of process fluids may cause personal
injury, loss of process control or environ-
mental contamination.
Controller Identification
Controller model numbers are typi-
cally 13 positions long (example:
2SM60-SRDA-BG). Refer to Table 1
— Model Designation on page 2 for
specific information on the controller
nomenclature.
A nameplate attached to the inside of
the case by the lower door hinge
includes the controller model and
serial numbers as well as other infor-
mation pertinent to the controller
assembly, such as supply and out-
put pressures, displacer material and
rating, body size and material, ANSI
class, and pressure and temperature
limits.
Always use only Norriseal replace-
ment parts when servicing level con-
trollers. Please refer to the serial and
model numbers when ordering
replacement parts.
