Specications

Diaphragm seals are used to isolate pressure measuring element of pressure gauges, pressure switches, pressure transmitters, andother pressure instruments from pressure media which may be corrosive, viscous, hot orsedimentary. The ange connection is directlyattached to the process by means of a ANSI, DIN, or JIS ange. The metal diaphragm is welded to the front of ange. This frontdiaphragm design improve the insufciency which the standard ange diaphragm seal maybe insensitive due to the media clogging within

an internal cavity. They are particularly suitablefor corrosive, heavily loaded or viscous mediawhich may damage or clog the process connection of the measuring instrument.

In order to reduce the temperature effect for the instrument, the cooling tower is recommended for the directly mounted instrument when temperature of the media > -120°C and capillary remote mounted instrument when temperature of the Media > 180°C
