导读：TMS-Y81射频导纳高温物位开关是一种新颖的电容式物位的换代产品,采用*的射频导纳技术,不受挂料、温度、压力、密度、湿度、甚至物料化学特性变化的影响（注明：克服电容式物位开关不能消除导电挂料影响的缺陷）。
Introduction: TMS-Y81 RF admittance level switch is a kind of high temperature capacitive novel position updating products, using radio frequency admittance technology advanced, not affected by hanging, temperature and pressure, density, humidity, even the material chemical properties change （Note: to overcome the SCAP cannot eliminate the defects of conductive coating effects of）.
结构原理
TMS-Y81射频导纳高温物位开关测量罐、槽、筒仓或的（液体、浆体、粉尘、颗粒以及两种液体界位）的料位控制及报警（堵煤强冲击、低料位加重型强冲击、酸碱强腐蚀）等介质。
The structure principle
TMS-Y81 RF admittance level switch high temperature measuring tank, tank, silo or （liquid, paste, powder, granule and two kinds of liquid level） of the material level control and alarm （coal blockage strong impact, low material level and severe shock, strong corrosion medium pH）.
