Safety, Installation, and Handling
-
Safety and installation: Refer to the installation and maintenance guide (IM-P027-17) supplied with the product for detailed information. As a precision measuring instrument, the gauge must be installed and used with particular care. Installing a shut-off valve is recommended to facilitate calibration and maintenance. In steam and hot gas service, use a U-type or ring-type syphon with a cock to prevent the pressure gauge from rupturing.
-
Handling: The product is recyclable and will not cause environmental problems when disposed of properly.
Ordering Example
Example: 1- Spirax Sarco pressure gauge, range 0 - 1.0 MPa, 3/8”BSP threaded connection
Spare Parts Information
The pressure gauge has no spare parts.
Typical Applications
-
U-type syphon and pressure gauge: Vertical piping, the side of a vessel, or above horizontal piping where space is limited.
-
Ring-type syphon and pressure gauge: The top of a vessel or horizontal piping where sufficient overhead space is available.
