Model: DS190(S)
Introduction
Diaphragm seals generally install on pressure gauge, switch, transmitter and other instruments to protect diaphragm from corrosive, crystallized, viscous and high temperature media that may cause blockage or damage to pressure measurement system. Different materials and pressure range can be chosen according to actual using media, connected pressure gauges, operating temperature and other factors.
Features
■ OEM service
■ Applicable to corrosive, crystallize, and viscous media
■ Screw fixed type, install a cleaning hole to directly clean the interior of diaphragm is available
■ With PTFE diaphragm, the min. measureable pressure is 4000mmH2O (Option)
