These Thermowells are turned & drilled from solid bar stock. This enables them to be placed within processes which experience or operate under high pressure. They consist of a stainless steel shaft which can be straight or tapered. This is welded onto the Tri_Clover which is drilled to suit the shaft. There is a lag at the back of Tri_Clover which houses an internal instrument connection thread. This unit is generally Polished to achieve a high surface finish. The bore is drilled out to 0.3mm larger than the intended sensor to be assembled giving a snug fit to encourage good thermal conductivity.
