Hawk Measurement Systems products

The Gladiator Acoustic Switch uses Acoustic Wave technology in a new Sender/Receiver form for blocked chute detection and anti collision for heavy machinery. The Gladiator Amplifier powers two AW Transducers which use special Hawk developed software where both units pulse and receive each others Acoustic echoes. When the path between the Transducers is blocked the units immediately detect the presence/absence change of the return signal and trigger a communications relay for indication or control purposes. The Transducers work both together and independently to detect pulse interference giving twice the application security.

The MiniWave emits an ultrasonic pulse, which is reflected from the surface of the liquid being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false echoes. Adaptive sensitivity control allows the unit to dynamically adjust and improve the received echoes for the best possible measurement outcome.

The HAWK range of Guided Radar products are ideal for the measurement of liquids, sludge, powders and granules to a range of 18.5m (60ft) for level and interface. This technology is not affected by pressure, temperature, viscosity, vacuum, foam, dust, changes in dielectric constant or coating of the probe.

To optimize performance in each interface application under all process environments: HAWK has developed a powerful low frequency transducer to penetrate through the suspended solids and capable of measuring the sludge bed level at the bottom of a clarifier or the lightest flocculent layer. To optimize performance under all process environments in each interface application: HAWK uses one transducer with a frequency and power level that is applicable to the density of the interface and process conditions expected in the tank. Also, HAWK can guarantee performance for controlling pumps etc, rather than for monitoring purposes only.

The ORCA Sonar Bed Level transducer emits a high powered acoustic pulse, which is reflected from the interface density selected. The reflected signal is processed using specially developed software algorithms, that eliminate lighter floating densities and stratified layers, allowing measurement of RAS or BED levels. It can be calibrated to measure lighter densities like FLOC or one of the outputs could be used for a CLARITY output, similar to a basic turbidity transmitter measuring solids in suspension. By choosing the correct sonar transducer frequency, the ORCA sonar guarantees the optimized performance when measuring both light and heavy density interfaces.

Based on the principle of magnetic coupling and buoyancy, the magnetic level gauge provides real-time measurement for level and interface.

The OptioLaser S200 series offers an optional visible alignment laser, RS232 and 4-20mA outputs. It uses an infrared semiconductor, GaAs laser diode. A light energy wavelength of approximately 905 nanometers, with a beam divergence of 3 milliradians (equal to 3ft at 1000ft), travels to the material being measured. Any solid or liquid target in its path, will reflect back a certain percentage of the emitted energy. The OptioLaser calculates the distance, based on the transit time the laser pulse travels to the material and back.
