Product Details
CYW501AY ceramic capacitance type input level transmitter shell is made of 316L stainless steel, the sensing core is made of ceramic capacitance measuring element, and the liquid-connecting part is made of ceramic material, which makes it have the characteristics of anti-stabbing, corrosion-resistant, high precision, high stability, and small blind zone. It can measure liquid, fluid or medium with particles. Explosion-proof function is optional.
