DIAPHRAGM PRESSURE GAUGE
Threaded Process Connection
DS148(W) series
*APPLICATIONS
Diaphragm pressure gauges are used when medium fluid is corrosive, contaminated, viscous and
crystalline or with impurities. DS148(W) series is particularly used in chemical and petrochemical
industry, mechanical engineering, plants and apparatus construction.
*SPECIFICATIONS
Instruments：All series pressure gauges and pressure transmitters are available
Process connection (Thread)：
1/2" PT (BSPT) / NPT, male and female thread, SS304 (C Type) or SS316 (J Type)
Note：
1. Generally PF (BSP) thread is not available because the inlet hole is too small and it will be clogged with viscous or crystallizing medium.
2. If the connection of wetted parts material is 1/4‖ or 3/8‖ PT, an additional connector is available.
