Pulsar - Model dB Transducer Series - Non-contacting Ultrasonic Transducers for Level Measurement
The Pulsar dB Transducer Series are ultrasonic transducers that can measure level in a wide range of liquids, powders and solids as well as open channel flow applications. The dB Transducers have a compact, low power transducer design that can be I.S. certified and uses standard interconnecting cables, yet produces extremely high acoustic power to give exceptional results in a wide variety of challenging situations. All transducers also have flammable atmosphere approval as standard. dB Transducers can be teamed with any of Pulsar's control units to create the perfect solution for your application.

Transducer Options
- Threaded Transducers : dB3, dB6 and dB10 are available with threaded noses for easy mounting. dB3 and dB6 models feature 1.5inch universal thread while dB10 has 2inch universal thread. All performance parameters of the transducers remain unchanged.
- Flanged Transducers : Available in a flange option, ANSI or DIN specification, all featuring full PTFE coating on the process wetted side, up to the dB15 size.
- Sanitary Flanged Transducers : For standard transducers up to dB10 an option of an sanitary flange construction exists. The flange has a full face PTFE or PVDF seal for use in hygienic applications.
- Foam Face Transducers : A foam face option is available for all standard range transducers to provide more acoustic power output in dry, dusty environments.
- Submergence Shield Transducers : A shield can be fitted to keep the transducer face clean and dry in applications at risk of submergence. The shield can be fitted on the standard transducers up to dB25 size. Note: All dB3 transducers are fitted with a shallow drip shield.
Applications
- liquids, powders and solids level measurement
- open channel flow measurement
- corrosive applications
- dry dusty environments
- risk of submergence applications
