FlangedTransducers
Flange options are available for dB3, dB6, dB10 and dB15 transducers, ANSI or DIN 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). See technical specifications for more details. These integral flange options are available with the standard family of transducers, up to the dB15 size.
A range of threaded nose transducers are available, 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. These are also available in PVDF for corrosive applications.
These integral flange options are available with the standard family of transducers, up to the dB15 size.
Transducer Options:
Foam Face
A foam faced option is available for all the standard range transducers to provide more acoustic power output in dry, dusty environments. This higher acoustic power output increases return echo strength in these dry applications. Not available on dB3 versions.
Submergence Shield
A shield can be fitted to keep the transducer face clean and dry in applications at risk of submergence. In case of submergence the controller can be asked to fail high, low or hold the last reading. When the level drops back below the shield it allows the controller to resume operation with a clean transducer face. The shield can be fitted to the dB3, dB6, dB10 and dB15 dB25 standard transducers. Note: All dB3 transducers are fitted with a shallow drip shield.
dBMACH3 - high accuracy open channel flow transducer
Featuring unique sun and submergence shields, the dBMACH3 transducer is designed specifically for open channel flow applications. dBMACH3 is the first ultrasonic transducer with zero effective blanking distance beyond the nose cone, allowing it to be sited as little as a few mm from the high flow level. One of the critical factors affecting ultrasonic accuracy is the measurement distance and air temperature, so by minimising this distance, accuracy is maximised. Operating at 125kHz frequency the transducer provides a resulting high resolution accuracy. Essential in open channel flow applications. This dBMACH3 is used with Ultra 3 or 5 and TWIN when in open channel flow mode.
Sanitary Flanged Transducers
For standard transducer from dB3 to dB10 an option of a sanitary flange construction exists. The flange has a full face PTFE or PVDF seal for use in hygienic applications. The flange is available in 2" or 3" (on dB3) and 3" on the dB6 and dB10 units. These flanges allow Tri-Clamp fittings to be used onto tanks or vessels.
Threaded Range Transducers:
dB3, dB6 and dB10 transducers are available with threaded noses for easy mounting. dB3 and dB6 models feature 1.5 inch universal thread while dB10 has a 2" universal thread. Standard transducer bodies are made from Valox 357 PBT with a special foam radiating face. All are available in optional PVDF version for corrosive applications. All performance parameters of the transducers remain unchanged.
