Single and Multi-Station Gauge Isolators
Hydac has developed both single and multi-station gauge isolators in order to effectively monitor and measure the operating and resting pressures in a hydraulic system. Hydac products are available through HFT of the Bosch Rexroth South Africa Group of Companies.
Single Station Gauge Isolators
Long life and continuous accuracy can be achieved if pressure gauges are only pressurised for the time it takes to read the pressure.
For the rest of the time the gauge isolator isolates the pressure gauge and the gauge is automatically vented to the tank. This then protects the gauge from possible pressure surges from the system. This is possible with the HYDAC Single Station Gauge Isolator.
It can be operated in two ways:
- Push button: the pressure is indicated as long as the button is depressed.
- Push button and turn clockwise through 90°: this locks the pressure indication until the button is released.
Multi-Station Gauge Isolators
Multi-station gauge isolators are designed to check different pressures in a hydraulic system.
There are models with a built-in pressure gauge for different pressure ranges or models to which a separate pressure gauge can be connected. If it is necessary for the system pressure to be retained during the measuring process, the leakage-free model must be used.
