RaloTex Diaphragm Pressure Gauges

Threaded Process Connection ----- Plastic material

DS418 series

 

 

Applications:

Diaphragm pressure gauges are used when medium is corrosive, contaminated, viscous, crystallizing or with particles. DS418 series is particularly used with high corrosive medium. Industries of chemical, plating, waste water treatment and fertilizer are the most common applications.

Technical data:

Instruments

All series pressure gauges and pressure transmitters are available

Process connection

(Thread)

1/4”; 3/8”; 1/2”; 3/4”; 1” PT (BSPT) / NPT, male or female thread Other connection available made-to-order.

Note: Generally PF (BSP) thread is not available because the inlet hole is too small and it will be clogged with viscous or crystallizing medium.
