### Basic information for diaphragm seal systems

| Version | Diaphragm seal with flange connection, cell-type |
|---|---|
| Other versions | ■ Per NACE 1) MR0175 / ISO 15156, use in H ₂ S-containing environments in oil and gas production ■ Per NACE 1) MR0103 / ISO 17945, metals resistant to hydrogen sulphide stress crack - ing ■ With pre-volume deflagration flame arrester 2) for mounting to zone 0 (EPL Ga); model 910.21; see data sheet AC 91.02 |
| Pressure range | The maximum permissible operating pressure must be determined individually for each diaphragm seal system. It is dependent on the operating temperature, the process connec- tion, the joining method, the system fill fluid and the mounted measuring instrument. |
| Connection to the instrument | Suitable connection adapter to the instrument (e.g.G½, G¼, ½NPTor ¼NPT) |
| Mounting type | Capillary with handling tube |
