Typical Applications

Description

The Pulsarpoint 200 series range of point level measurement systems offers the very latest state of the art technology applied to the well respected vibrating blade principle of operation. All units in the range are manufactured to the highest standard from 316 solid stainless steel for maximum strength durability and corrosion resistance. Series 200 provides highly reliable, fixed point level indication or control with a repeatability of 1mm or better. Versions are available to measure, solids and slurries with relay output. The Pulsarpoint 200 series uniquely combines solid rugged construction with high sensitivity to produce maximum reliability. The unique blade design allows 'tip sensitive' control and the unit does not react to troublesome material build up on vessel walls.

Application

Pulsarpoint 200 is a universal point level indication switch which is mounted in the vessel to be monitored at the appropriate indication point. It is offered in different mounting arrangements to suit various applications. Standard units may be extended in length using tubular or cable extensions to suit customer requirements. Pulsarpoint may be used to measure all solids including very light density powders and granules. It is not affected by turbulence, dust clouds or agitation. High temperature and liquid/solid interface along with rigid or cable extension versions are also available.

Operation

Pulsarpoint 200 series employs the continuous vibrating element technique to detect the presence or absence of slurry or solid materials at the point in a vessel where the device is mounted. The single blade sensing element is vibrated at high frequency by a piezo-electric crystal from within the device. In the absence of material at the sensing point the blade freely vibrates. When material comes into contact with the blade, the frequency of oscillation is changed or damped. This event is detected by a second piezo electric crystal and a signal is generated to provide an output to indicate the change of state at this point within the vessel. The vibrating action and the shape of the blade produces a self cleaning action when the material level falls away and blade oscillation resumes.
