Ultrasonic dB Transducer Series

Non-contacting sensors for level, volume and flow - liquids and solids

dB Ultrasonic Level Transducer Models

Pulsar's dB ultrasonic transducers offer reliable level, volume, open channel flow, pump control and differential measurement within liquid and solids applications. dB ultrasonic sensors utilise a low power transducer design with standard interconnecting cables - yet produce extremely high acoustic power to give exceptional results in a wide variety of challenging applications.

Transducer Options Explained:-

PVDF transducer on a diesel tank Pulsar PVDF level transducer

PVDF face

A PVDF face is suitable for many applications where chemicals are present. Please consult Pulsar regarding your application needs. 




Ultrasonic level transducer with submergence shield Pulsar Submergence Shield Transducer

Submergence Shield

A shield can be fitted during manufacture to keep the transducer face clean and dry in applications at risk of submergence. In this situation, the transducer continues to read a high level. When the level drops back below the shield, it allows the controller to resume operation with a clean transducer face.

  PVDF front threaded ultrasonic transducer on a diesel tankPulsar Front Threaded Ultrasonic Transducers

Front Threaded Versions

Available in standard or PVDF options. Front threaded versions allow for easy mounting - either 1.5" or 2" BSP/NPT nose thread.

 

Pulsar Flanged Transducer in an Industrial ApplicationPulsar Flanged Level Sensor

Flanged Transducers

Available in DIN or ANSI flange specification - all featuring full PTFE coating on the process wetted side. Various flange sizes are available. Maximum vessel pressure on flanges is 0.5bar (7psi). These incorporate the performance features of the standard products but additionally offer a front thread mount option to suit threaded nozzles or flanged tank entries. PTFE is a chemical resistant material - please consult Pulsar regarding your application needs. 

  Pulsar Foam Face TransducerPulsar Foam Face Ultrasonic Sensor

Foam Face

A foam faced transducer provides more acoustic power output in dry and dusty environments. This higher acoustic power output increases return echo strength in these dry applications.

 

Sanitary Flange

A santiary flange option includes a full face PVDF seal for use in hygienic applications and 3" sanitary flange which allow Tri-Clamp fittings to be used on tanks or vessels.
