6 .1 General
Gas type: natural gas, town gas, LPG (gaseous), flue
gas, biogas (max. 0.1 %-by-vol. H
2
S) and air.
Max. inlet pressure p
max.
= withstand pressure, see
page 22 (Adjusting range, switching hysteresis).
Electrical connection type: screw terminals.
Diaphragm pressure switch, silicone-free.
Diaphragm: NBR.
Housing: glass fibre reinforced PBT plastic with low gas
release.
Lower housing section: AlSi 12.
Enclosure: IP 65, safety class: 1.
Max. medium and ambient temperatures, see
page 21 (EU certified pressure switches) and
page 22 (UL, FM certified pressure switches).
Storage and transport temperature:
-20 to +40°C (-4 to +104°F).
Long-term use in the upper ambient temperature range
accelerates the ageing of the elastomer materials and
reduces the service life (please contact manufacturer).
The set switching point may palpably change in media
and ambient temperatures below -22°F (-30 °C).
