### Basic information

| Standard | EN ISO 16852:2016 'Flame arresters …' |
|---|---|
| Measuring assembly |  |
| Variant 1 | Pressure gauge with Ex approval and integrated model 910.21 |
| Variant 2 | Diaphragm seal system 1) with integrated model 910.21 |
| Permissible media | Flammable gases and vapours occurring during operation may be classified into explosion group IIC with a nominal gap width of ≥ 0.29 mm.The use for explosive gas, mist, vapour or air mixtures which are volatile (e.g. acetylene, carbon disulfide) or for chemically instable substances is not permitted. |
| Material (wetted) |  |
| Variant 1 | ■ Stainless steel (typically) ■ Special materials such as the wetted parts of the pressure gauge, e.g. Monel, Hastelloy |
| Variant 2 | Model 910.21 is non-wetted |
| Components of the measuring assembly | Mounting parts, such as cooling elements, connection adapters, capillaries, etc., are located on the protected process side. Measuring assemblies with capillaries are, generally, protected ex-works with a capillary protective tube (wall thickness approx. 0.2 mm). |

### Further details on: Measuring assembly, variant 1 Pressure gauge with Ex approval and integrated model 910.21

| Pressure gauge with Ex approval | ■ Pressure gauge (e.g. models 232.50, 432.50, 732.51) ■ Contact pressure gauge (e.g.PGS23, PGS43, DPGS43) ■ Pressure gauge with output signal (e.g.PGT23, PGT43, DPGT43) |
|---|---|

### Further details on: Measuring assembly, variant 2 Diaphragm seal system with integrated model 910.21

| Pressure measuring instrument with Ex approval | ■ Pressure gauge (e.g. models 232.50, PGS43, DPGT43) ■ Model CPG1500 ■ Model IS-3 ■ Model UPT-20 ■ Model IPT-20 ■ Model DPT-10 |
|---|---|
| Diaphragm seal | ■ Diaphragm seal with flange connection ■ Diaphragm seal with threaded connection ■ In-line diaphragm seal ■ Diaphragm seal with sterile connection |

### Operating conditions

| Lu/D=n/a | Ratio of the pipe length of the unprotected side to the pipe diameter |
|---|---|
| BC:c | Classification under stabilised combustion, combustion classification c (no burn time) |
| -40 °C ≤ T 0 ≤ 60 °C | Permissible operating temperature The measuring point for the permissible temperature in the final application is the position symbol of the zone separation. |
| P 0 = 1.1 bar | Maximum ambient pressure |
