| 摘要 |
The invention relates to a tubular insert for a magnetically inductive flowmeter, a production method for said type of tubular insert and a flowmeter. The tubular insert (6) is made of, essentially, an electrically-insulating material, in particular, rubber, which is reinforced by a tubular moulding part made of a dimensionally stable plastic which is based on polymers (7), at least in a measuring section. The tubular moulding part (7) is embedded in the electrically-insulating rubber material by a press or casting method such that the electrically-insulating, rubber material essentially covers the inner surfaces (30, 31) of the tubular moulding part. An economical to produce, robust, tubular insert is thus achieved. |
