VEGA has extended its radar sensor portfolio with a new instrument series. The 80 GHz-based sensors are suitable for more price-sensitive applications, such as those found in the water and wastewater industry. With their precise focusing, they deliver reliable measured values regardless of external conditions such as temperature or build-up on the sensor.

The new instrument series is available as compact version with cable connection compartment or with fixed cable connection (IP68). VEGAPULS operates with a transmission frequency of 80 GHz. With an 80mm antenna, this yields a beam angle of only 3°. This means the radar sensor only receives clear, distinct reflections from the measured medium. This makes the measurement even more accurate and reliable.

By comparison: A conventional radar sensor with 26-GHz transmission frequency and the same antenna size has a beam angle of about 10°. Due to the much wider signal beam, agitators, internal fixtures or build-up on the vessel wall cause interference that can affect the measuring result.

Compared to ultrasonic sensors, no false signal suppression is necessary. The new VEGAPULS instrument series is also not bothered by condensate or dirt.

The instrument series is complemented by VEGAMET controllers, which feature a large graphic display that can be used to visualise all measured values.  Since it was specially designed to meet the needs of the water and wastewater industry, the instrument series is ideal for simple implementation of pump control, flow measurement in open channels or overfill protection according to WHG. The controllers have a weatherproof field housing to protect them against the effects of weather.

All instruments can be easily adjusted via Bluetooth with a smartphone or tablet. This makes parameterisation, display and diagnostics considerably easier, especially in harsh environments or hazardous areas.
