Pressure transmitter 556
The pressure transmitter type 556 has been developed for static
applications, e.g. for refueling hydrogen stations. This highpressure
transmitter is ATEX and IECex certified and is available
with protection rating IP 67 or IP 69K.
The measuring cell is based on the Huba Control developed
thick film technology on stainless steel and is fully hermetically
welded.
- Suitable for gaseous hydrogen
- Compact and robust design for maximum operational safety
- Welded without seals
- 100 % inline helium leak test during production
- Excellent EMC properties
