Brand: Ihne & Tesch / Keller Ihne + Tesch.
Model: TEF SP clamp‑on thermocouple sensor for pipe diameters Ø40–Ø60 mm, part no. 1100147, Fe‑CuNi Type L with 2.000 mm DR cable, date 28 Nov 2018.
Condition: New old stock, never used, in original factory plastic bag; sensor, clamp band and cable appear clean with no installation marks. Perfect as a spare or retrofit sensor for industrial heating systems, process pipes and machinery.
Technical specifications (from label and manufacturer data):
-
Sensor type: Thermocouple Type L (Fe‑CuNi), DIN 43710, similar characteristics to Type J.
-
Design: TEF SP strap/clamp sensor for mounting around cylindrical surfaces (pipes, heater bands) Ø40–Ø60 mm.
-
Cable: 2.0 m flexible thermocouple cable with braided insulation and strain‑relief spring at sensor head.
-
Typical temperature range for Fe‑CuNi Type L: approximately +100 to +600 °C, suitable for many industrial heating applications.
Main features:
-
Easy clamp‑on installation with included stainless‑steel band for secure, repeatable contact on pipes or nozzles.
-
Rugged construction and braided cable for reliable service in demanding environments such as plastics processing, packaging and general industrial heating.
-
European‑made sensor from a specialist in electric heating and temperature control, compatible with many temperature controllers and PLC inputs that accept Fe‑CuNi L or J‑type ranges.
Background / application information:
Type L Fe‑CuNi thermocouples are widely used in older European installations and remain popular in heating technology thanks to their stability in the typical industrial temperature band. Clamp‑on TEF SP sensors from Ihne & Tesch are commonly used on heater bands, extruder barrels, injection moulding machines and process pipes where drilling sensor holes is not possible.
Please confirm sensor type (L / Fe‑CuNi), mounting diameter range and cable length are suitable for your equipment before ordering. Additional details can be found in the Ihne & Tesch temperature sensor technical information and stock program documentation available online.
