6.3 Coil housing configuration
The coil housing provides physical protection of the coils and other internal components
from contamination and physical damage that might occur in an industrial environment.
The coil housing is an all-welded and gasket-free design.
The MS sensor model is available in four coil housing configurations. Configurations are
identified by the M0, M1, M2, or M4 options codes found in the model number.
6.3.1 Standard coil housing configuration
The standard coil housing configuration is a factory sealed all-welded enclosure and is
available for the following models (see Figure 6-12):
• MS with option code M0 - MSxxxxxxxxxxxxM0

B. No relief port (welded shut or absent)
6.3.2
Process leak protection (option M1)
The sensor is available with process leak detection through the use of a threaded
connection and pressure relief valve (PRV). This coil housing configuration is a factory
sealed all-welded enclosure.
• MS with option code M1 - MSxxxxxxxxxxxxM1
A PRV can be installed in the threaded connection to prevent possible over-pressuring of
the coil housing caused by a primary seal failure. The PRV is capable of venting fugitive
emissions when pressure inside the coil housing exceeds five psi. Additional piping may be
connected to the PRV to drain any process leakage to a safe location (see Figure 6-13).
In the event of a primary seal failure, this configuration will not protect the coils or other
internal components of the sensor from exposure to the process fluid.
