Abstract
Electro-chemical sensor for the detection of ion activity comprises a selective glas membrane (4) in direct contact with a metal electrode (3) or in direct contact with a variable conducting glas layer (4a), which is itself in contact with (3). (3), (4) and (4a) are plated onto a steel-ceramic substrate using screen-print technology. The thermal expansion coefficients of the steel-ceramic substrate and the glas layers differ by a maximum of = 6 multiply 10-7 K-1. USE - The sensor is especially useful in the detection of hydrogen, sodium, calcium, ammonium and silver ions in environmental measurements, bio and medical technology, and in the food and chemical indu...
