JUMO Mineral-Insulated RTD Temperature Probe

Overview

JUMO Mineral-Insulated RTD Temperature Probe is a flexible resistance thermometer built according to DIN EN 60751, engineered for chemical plants, power plants, pipelines, engine building, and test rigs wherever measuring locations require flexibility and simple replacement. Featuring a flexible, thin-walled stainless steel sheath cable with a vibration-resistant measuring insert, the JUMO Mineral-Insulated RTD Temperature Probe covers an exceptionally wide temperature range from -50°C (or -200°C on select variants) up to +600°C.

As the official authorized partner and exclusive regional representative for JUMO, Seven Star LLC proudly supplies the JUMO Mineral-Insulated RTD Temperature Probe to chemical, power generation, and industrial customers across Oman and the wider GCC. Every unit shipped through Seven Star LLC is genuine JUMO product with full manufacturer warranty and access to local technical support – ensuring facility engineers and procurement teams in Muscat, Sohar, and Salalah receive an authentic, factory-certified JUMO Mineral-Insulated RTD Temperature Probe backed by regional service.

Working Principle

The JUMO Mineral-Insulated RTD Temperature Probe operates on the resistance temperature detector principle: inside a flexible, thin-walled sheathed cable made of stainless steel, low-ohmic conductor copper wires are embedded in compressed, heat-resistant magnesium oxide, providing continuous electrical insulation while transferring heat efficiently to the Pt100 or Pt1000 sensing element at the tip. The temperature sensor is connected to the conductor in two-wire, three-wire, or four-wire technology, and as process temperature changes the platinum element’s electrical resistance changes in a precise, DIN EN 60751-compliant relationship, giving a standardized and repeatable measurement.

This mineral-insulated construction gives the probe its defining response speed and durability advantage: the compressed magnesium oxide insulation conducts heat quickly to the sensing element while damping mechanical vibration that would otherwise fatigue a conventional wired sensor over time. Response times as fast as t0.5 = 0.4 m/s in water or 3 m/s in air reflect the thin, flexible sheath’s ability to transfer thermal changes to the sensor rapidly, making the probe suitable for process loops requiring quick temperature feedback.

Engineering Design of the JUMO Mineral-Insulated RTD Temperature Probe

The JUMO Mineral-Insulated RTD Temperature Probe is available with connecting cables in PVC (-5°C to +80/+105°C), silicone (-50°C to +180°C), PTFE (-190°C to +260°C), or metal-braided cable (-50°C to +350°C), allowing the cable material to be matched to the ambient conditions surrounding the installation. The protection tube itself is manufactured from stainless steel 1.4541, and cable ends can be supplied stripped bare or fitted with ferrules, plug-in sleeves, or multi-pole electrical connectors according to the termination requirements of the connected instrumentation.

Process connections include screw connections in G1/2, G1/4, G3/8, M8, and 1/2-14 NPT sizes, and the probe is available as a single or double RTD temperature probe, with sheath diameters of 1.9 mm, 3 mm, or 6 mm, and insertion lengths from 100 mm up to 1000 mm to match application-specific mounting requirements. The standard adapter sleeve (end closure) is rated up to 120°C, with a 300°C-rated version available for higher-temperature connecting-head applications.

Key Features

The JUMO Mineral-Insulated RTD Temperature Probe combines a flexible, vibration-resistant sheath design with a wide operating envelope that makes it a standard choice for demanding process temperature measurement.

• A flexible, thin-walled stainless steel sheath cable with vibration-resistant measuring insert supports demanding mechanical environments.
• Temperature range from -50°C (or -200°C) up to +600°C covers cryogenic through high-temperature furnace applications.
• Fast response times (t0.5 as low as 0.4 m/s in water, 3 m/s in air) support quick-reacting process control loops.
• Multiple cable materials (PVC, silicone, PTFE, metal-braided) match the connecting cable to ambient installation conditions.
• Single or double RTD configurations in two-, three-, or four-wire circuits support redundant or high-accuracy measurement schemes.
• Application-specific insertion lengths and multiple sheath diameters allow precise fit to the process thermowell or direct insertion point.
• Multiple cable termination options (bare, ferrules, plug-in sleeves, multi-pole connectors) simplify field wiring.
• Compliance with DIN EN 60751 ensures standardized, interchangeable Pt100/Pt1000 measurement characteristics.
