VA 525 G 1 1/2" - Compact sensor for precise measurement of compressed air and nitrogen
The newly developed VA 525 compact sensor combines modern digital interfaces for optimum connection to energy monitoring systems with a compact design. It is used in particular when several compressed air consumers need to be integrated into an energy monitoring network.
Reduce your energy costs and increase the sustainability of your company with the VA 525. Monitor the consumption of individual machines and analyze leaks with just one powerful measuring device.
Advantages of the compact VA 525 flow sensor:
- Precise measurement of the mass flow rate: The VA 525 provides a direct output of the standard volume flow rate without the need for additional measurements of pressure and temperature.
- Compact design: The device is ideal for installation in confined spaces and requires no inlet and outlet sections thanks to the integrated flow straightener.
- Optional pressure sensor: The VA 525 is also available with an integrated pressure sensor.
- Highly accurate: It delivers precise measured values at both low and high flow rates.
- Low maintenance: As there are no moving parts, the sensor is particularly easy to maintain.
- Versatile use: The VA 525 is suitable for both compressed air and nitrogen.
Technical details of the VA 525:
- Serial interfaces: 04...20 mA and pulse as well as Modbus RTU (RS 485).
- Optional interfaces: Modbus TCP (Ethernet), PoE, M-Bus are also available.
- Pressure range: Up to 16 bar.
- Temperature range: Up to 60 °C.
- Integrated display: Clearly shows the measured values.
- Available sizes: Available in sizes from 1/4" to 2".
- User-friendly settings: Adjustments can be made directly via the buttons on the display.
- Restoring the main counter reading: Can be reset via the display.
- Machining speed: Suitable for speeds up to 224 Nm/s.
- High accuracy: With an accuracy of ±1.5% or ±1% of the measured value and ±0.3% of the final value.
Use the VA 525 to monitor your compressed air and nitrogen systems more effectively and optimize your operating costs with precise measurements and innovative technologies.
