This data sheet contains ordering information, minimum pressure ranges, information about the electrical connections and dimensional drawings of diaphragm pressure gauges models PCh and PChOe with limit-switch contact assemblies.
Data sheet 3201 contains all important features of model PCh and PChG without electrical accessories. These technical details are also valid for gauges assembled with limit-switch contacts, as far as you don't find a deviating description below. The ordering code for the liquid-filled version with limit-switch contact assemblies is Oe instead of G. The filling liquid is a special oil.
For detailed information about use and operation of mechanical,inductive, electronic and pneumatic limit-switch contact assemblies please note our general information leaflet 9000, and for further information, especially about the available make/break operations, see the data sheets for the individual models of limit-switch contact assemblies:

Pneumatic Data sheet 9300

Minimum Pressure Ranges
Every pressure gauge needs a sufficient amount of torque the limit-switch contacts with minimized error. For this reason following miminum pressure ranges are to consider1):

1) lower pressure ranges upon request
2) 4 contacts for pressure gauges nominal case size 100 (4") upon request
3) 4 contacts upon request
Pneumatic limit-switches in nom. sizes 100 (4") are only available as
single contacts.
For pressure gauges with 3 or 4 contacts it is no
