| Say all:
The YLH30 series intelligence type the radar thing account(YLH31,YLH32,YLH33,YLH34), not the contact type and consecution measure of the pulse type the thing account the biggest diagraph to be apart from a 70 ms.Be applicable to professions, such as petroleum,chemical engineering,running water,dirty water processing,water conservancy hydrology,steel,coal mine,electric power,transportation and food processing...etc..
The characteristic and advantage:
Have no blind area, high accuracy
Two lines system techniques, is differ to press appearance, with the result that the stretch and shrink,radio frequency leads ,to turn over the plank gauge of good act for a product.
Be free from the environment influences, such as pressure variety,vacuum,the temperature variety,sloth air,smoke and dust and steam...etc.
Install simple, firm enduring, don't need a maintenance
The HART or PROFIBUS-PA correspondence agreement and foundation the spot total line agreement, mark settle simple,show through a numerical LCD relaxed carry out the spot a mark settle operation, carry out a simple set enactment and weave a distance through the software SDPF
Measure intelligent, break speed quick.
Be applicable to the heat work condition, be up to 200 ℃ process temperatures, be the adoption heat extension antenna can reach to 350 ℃s
Measure principle:
The radar thing accounts antenna to send out the microwave pulse, being being measure the material surface creation glint, and drive radar screen receive.
