BH93420-I 4-20mA Water Level Transmitter with 316L Stainless Steel IP68
BH93420-I Diffused Silicon Water Sensor
This diffused silicon water sensor uses HT series diffused silicon isolation oil-filled core as its signal measuring element. Designed with a full stainless steel housing and compact one-piece structure, the sensing part is completely sealed with stainless steel for excellent waterproof performance. Rigorous high and low-temperature compensation and aging tests ensure high reliability and stability.
