Coding of Series 700
Process Options
Series
700 pressure switches may be used
for monitoring the pressure of inert processes such as air or nitrogen,
or aggressive processes such as ammonia or nitric acid. Both the
Diaphragm and the Pressure (or DP) Chamber(s) of the switch are in
contact with the process so clearly the materials of both must be
chosen to be compatible with the process.
If assistance is required in determining the suitability of a diaphragm
or chamber material with your process please contact Hamall. Additional
non-standard options are also available Hamall can advise you of these.
