Stainless Steel Radar Level Transmitter, For Liquid Measuring

Extremely short microwave pulses with low emitted power are transmitted by the antenna system to the measured product, reflected by the product surface and received back by the antenna system. Radar waves travel at the speed of light. The time from emission to reception of the signals is proportional to the level in the vessel. A special time stretching procedure ensures reliable and precise measurement of the extremely short transmission periods.
The propagation of microwaves is virtually unaffected by the ambient temperature and pressure. Hence these radar sensors are ideal for use under extremely difficult process conditions. Pressures from vacuum up to 160 bar(2320 psi) and temperatures from - 40 ... +400 °C (-40 ... +752 °F) are no problem for radar.
