Seal ring for metal sealing. After sealing has been achieved, the pressure gauge can still be turned by 360°, so that any desired position can be set.

Installation information

When assembling the measuring line at the pressure gauge, the pressure gage connection piece (SW14; SW22) is to be held by means of a counter wrench. Bleeding and/or pressure relief openingThe pressure gauges are equipped with bleeding facilities at the top side of the housings. Before commissioning the pressure gauges, the bleeding facilities are to be manually set from the “closed” position to the “open” position in order to avoid measuring errors.

Marking on the dial

On dual scales, the lettering of the outer scale division (bar) is black, that of the inner scale division red.

Note: Single or dual scales for other pressure ranges (psi, kPa, MPa) on request.

Safety note according to Pressure Equipment Directive 97/23/EC

Pressure gauges are classified as pressure-holding equipment according to Article 1, Paragraph 2.1.4 of the Pressure Equipment Directive. The volume of the pressurised housings is < 0,1 l.

According to Annex 2, Diagram 4 (fluids) and Diagram 2 (nitrogen) the pressure gauges according to the present data sheet R.50205 are subject to the Pressure Equipment Directive up to PS = 1000 bar. According to Article 3, Paragraph 3 they are manufactured according to "good engineering practice" and are not CE-marked.

Use in potentially explosive atmospheres according to Directive 94/9/EC (ATEX)

The pressure gauges are provided with stainless steel housings which cannot generate igniting sparks according to DIN EN 13463-5.

The maximum surface temperature depends not on the pressure gauges, but mainly on the relevant fluid temperature and must therefore be assessed within the risk analysis of the power unit/block.

Because the pressure gauge according to the present data sheet R.50205 do not include any potential sources of ignition, they do not fall under the ATEX Directive and are not CE-marked.
