Pressure transmitter

OEM relative pressuretransmitter
Type 505
Type 505 pressure transmitters are particularly suitable formeasuring water pressure rates in heating and industrial
circular flow.
Due to partially automated manfacturing we are able to handle
customer orders in high quantities.

Pressure range
0 ... 4 – 16 bar+ Best price / performance ratio through:– electronic integrated in measuring element– optimised mounting concept– automatic production+ Ideal for use as a control element, owing to small
hysteresis+ The measuring element includes the well provenceramic technology of Huba Control AG
