<p>A manometer of simple design and therefore economical to manufacture is particularly suitable for use in the case of abrupt changes in pressure in a humid, conductive medium, principally in hydraulic engineering. To this end, the invention proposes that even when a protective layer (15) of glass covers the measuring resistances on the manometric cell (9), this glass layer is omitted or removed in the contact region (20) of the leads (23). In this region, a glass-free material is cast to protect the connection regions. The manometric cell is fixed to a support (19) and protected by the glass-free material (29).</p> |
