mmWAVE: a compact FMCW RADAR sensor

Pulsar Process Measurement has launched mmWAVE, a compact FMCW RADAR sensor that offers high accuracy, repeatable level measurement and compatibility with Pulsar’s full range of level controllers.

That means that Pulsar customers can choose between mmWAVE RADAR and dB ultrasonic measurement without having to make any compromises in terms of functionality – they choose the right control solution and simply pair it with the appropriate measurement technology for the application.



RADAR and non-contacting ultrasonic measurement are complementary non-contacting technologies – measuring level by signal analysis but excelling in different situations.

RADAR is preferred where there is variation in temperature or changes in gas composition, and extremes of fog, haze, mist or rain, so users can now introduce Pulsar’s sophisticated control functionality into new applications.

mmWAVE RADAR is a Frequency Modulated Continuous Wave (FMCW) transducer with a 16m range and accuracy of ±2mm.

FMCW RADAR offers significant advantages over pulsed RADAR systems – higher resolution, better signal to noise ratio and better target discrimination.

A major benefit to customers is that mmWAVE sensors are compatible with existing Pulsar controllers already installed and used in the field, such as Ultra 3 and Ultra 5.

This means that sites can retrofit a RADAR sensor within their existing applications, redeploy Pulsar equipment across a wider range of applications for maximum flexibility, or test the performance of different measurement technologies without having to significantly reconfigure the device.

Commenting on the development, Pulsar’s Sales & Marketing Director, Alistair MacKinnon said, “Pulsar is known all over the world for its ultrasonic systems control and communication functions that have been developed over 20 years to meet the needs of a wide range of industries and processes.

“mmWAVE RADAR now allows us to broaden that approach to new markets and new applications.”
