Description
HYDRA-line
Our pressure measuring instruments of the HYDRA-line product family have been developed in co-operation with well-known customers in the semiconductor industry. The complete product concept has been adapted to the special requirements of the process equipment and UHP chemicals distribution system sectors.
The HYDRA-Dry pressure transducer offers high accuracy and reliability, ultra clean wetted parts and surfaces.
There is no fill fluid which avoids possible process contamination.
Furthermore, the production of all wetted parts, cleaning assembly, calibration and packaging takes place in a class 100 cleanroom.
Double safety
The patented HYDRA double diaphragm system enables a safe and reliable separation of the pressure sensor from the process medium. Simultaneously diffusing process media such as HF or HCI vapours are given off to the environment to avoid any falsification of the measuring result or the destruction of the sensor element.

Dynamic
The digital indicator Model HYDRA-Indicator offers a unique solution for a local display of the process pressure at the transducer Model HYDRA-Dry. With this HYDRAIndicator, which has been specially designed for the UHP market, a signal and freely adjustable switch points can be transmitted simultaneously. Its scale can be fully adjusted directly on site without master instrument.
Unit (psi, bar, kPa, MPa and kg/cm2), decimal point, display range, zero point and switch points can be adjusted via the control keys.
Comfortable
Power is directly supplied by the 4 ... 20 mA-loop, i.e. no extra power supply is required.
Practical
The seven millimetre high, red LED display is easy to read.
In order to be able to adapt the HYDRA-Indicator to the application, it is available in two different versions:
