| | Construction The GEMU C30 Hydra-Gauge is equipped with a PFA transmitter and a pressure gauge. The body is made from PFA and can be directly integrated into the pipe system by commom flare unions. A PFA double diaphragm prevents contamination of the working medium. Only the PFA body and the PFA diaphragm are wetted parts. The pressure is transmitted by a monitor liquid (50 % Dl water and 50% IPA (isopropyl alcohol)). The pressure gauge complies with EN 837-1.
Features
- C30 is especially suitable for pressure measurement of ultra high purity chemicals
- All wetted parts are made from High Purity PFA
- Pressure transmission by double diaphragm technology
- Pressure gauge can be rotated through 360°
- Not suitable for applications with strong vibrations, pulsing process pressure or pressure peaks; provide for suitable pulsation dampers and throttling sections, if necessary
Advantages
- Minimal deadleg
- The proven GEMU CleanStar® technology is the basis of the transmitter
- Working medium hermetically isolated from the gauge by a double diaphragm
- Proven long term reliability
- Pressure gauge can be positioned through 360° enabling individual user options

Switching Functions1
| | Break Contact: Opens as pressure decreases Make Contact: Closes as pressure increases
| |
Inductive Contact | | Non-touching switch, no wear, high reliability, Ex approval, additional switching unit required
| |
Magnetic Spring Contact | | Open contacts, can switch power directly
| |
Electronic Contact | | Inductive contact with integrated switching amplifier, non-touching switch, high reliability, for direct connection to a PLC or piloting relays
| |
1 The switching function is irrelevant when piloting a PLC.
