Description
The TEFRACTO-PAD ® model TC59-T is the first development in the WIKA Houston R&D center. Taking into account the knowledge of customer applications, needs and requirements the product addresses proven accuracy and ease of installation. The proprietary thermal shield design of the TEFRACTO-PAD ® is a patent-pending WIKA innovation in several countries (patent pending, property right: US 17/554,754, EP 21215402.5 and CN 202111548816.4).
The TEFRACTO-PAD ® sensor hot end is a contoured weld-pad and optimised heat shield attached to a mineralinsulated cable (sheathed cable). It consists of a metal outer sheath, which contains the insulated internal leads, compressed within a high-density ceramic composition. The material of the outer sheath can be selected to match the application. At the hot end of the sheathed cable, the internal leads are welded together to form an insulated (ungrounded) or non-insulated (grounded) measuring location.
A proprietary moldable shield is placed over the thermopad and sheathed cable. This shield and insulation is a key component for the TEFRACTO-PAD ® , providing accurate
Special features
- Proprietary thermal shield design, integrated one-step installation
- Application ranges from 0 ... 1,260 °C [32 ... 2,300 °F]
- Flexible sheathed cable, mineral-insulated internal leads
- High mechanical strength, shock-resistant
