Acoustic Wave Level Transmitters suit difficult environments.

Press Release Summary:

Powered using 2-wire (loop power) or 3-/4-wire sources, SULTAN Series emits acoustic wave pulse that reflects from surface of material being measured and is processed using software to enhance correct signal and reject false or spurious echoes. Measured signal is temperature-compensated for optimal output and display accuracy. Operating over 393 ft range, non-contact solution utilizes Adaptive Gain Technology and is compatible with HART, GOSHAWK, MODBUS, Profibus, and Fieldbus.

Original Press Release:

The SULTAN Series of Acoustic Wave Level Transmitters

Hawk Measurement announces the release of the Hawk SULTAN Series of acoustic wave level transmitters with Smart card 2-wire / 3 or 4 wire configuration.

Hawk, a leading global provider of level, positioning and flow measurement technology introduces the Sultan 234, which can be powered using loop power (2-wire), 3, or 4 wire sources. It does not matter which power source you choose... the Sultan Acoustic wave can measure in difficult environments. These powerful and effective instruments emit an acoustic wave pulse, which is then reflected from the surface of the material being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false or spurious echoes. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display. This principle of operation elevated the Hawk SULTAN range to one of the most powerful level measurement systems on the market. This is a high-power device with long-range capability even on 2-wire loop power. There is no direct contact with the media, which can extend up to 393 feet (80 meters) from the sensor. The combination of low frequency, high power and signal processing (Adaptive Gain Technology) creates one of the world's most reliable level devices available.

Always a leader in innovation, Hawk has engineered its superior product to be compatible with HART, GOSHAWK, MODBUS, Profibus, and Fieldbus. There are a wide range of transducers to choose from, making the SULTAN Series suitable not only for the prime area's of application (waste water, mining, and power stations), but also food, cement, plastics, chemicals, paper, and quarries. The SULTAN Series form of acoustic wave transmission is on the breaking edge of innovation, making this the most effective and reliable instrumentation in the market today.
