Bourdon tube pressure gauges with additional electrical accessory (data sheet 1201.90)
The data sheet contains information on the maximum possible number of contacts, on electrical connections, ordering information and options concerning the models RCh and RChOe with limit switch contact assemblies (with low-action, magnetic, electronic or inductive contacts), as well as dimensional drawings with the position of the electrical connections.
Data sheet 1201 contains all details concerning the available versions of models RCh and RChG without limit switches. These details as well as the required ordering information apply also to the version with limit switches, unless otherwise stated in data sheet 1201.90.
Instead of glycerin, a special oil is used for liquid-filled pressure gauges with limit switches. The model code for instruments with case filling is RChOe.
