Description
Field of application:
- Measuring directly after the compressor
- Measuring at high temperatures
- Measuring fast processes
Advantages of the differential pressure sensor VD 500:
- Proven measuring principle by measuring the differential pressure (dynamic pressure)
- Pressure and temperature compensated, thus output of the standard volume flow rate
- Particularly suitable for extremely high flow rates
- Extremely fast response time of 100 ms
- Quick and easy installation via a ½” ball valve
- No moving parts, therefore low maintenance effort
- Negligible low pressure loss due to negligible low blockage of the diameter
- Applicable for wet and hot compressed air directly after the compressor
Typical applications:
- Measurement of the delivery quantity of compressors
- Compressed air audits
- Efficiency measurement of compressed air systems
Installation conditions:
- After working water separator
- In horizontal lines (recommended) or in risers
Technical details:
- 04…20 mA, pulse and a Modbus RTU (RS 485) interface as standard
- Optional interfaces like Modbus TCP (Ethernet), PoE, M-Bus
- Pressure range up to 20 bar
- Temperature range up to 180°C
- Integrated display to show the measured values
- Available from DN20 to DN500
- Easy installation under pressure
- Settings adjustable via the keys of the display
- Main counter reading can be reset via the display
- Can be used for velocities up to 600 Nm/s
- High accuracy with 1.5% deviation of the measured value
