JUMO 902030 Screw-In RTD Temperature Probe

Overview

JUMO 902030 is a screw-in RTD temperature probe with a Form J terminal head, engineered for reliable direct-immersion measurement in mechanical engineering, thermostat baths, gearbox construction, and food and beverage processing lines. Available with Pt100, Pt500, or Pt1000 sensing elements in Class 1 or Class 2 accuracy, and in sheath diameters of 6, 7, or 8 mm with insertion lengths from 50 mm to 500 mm, the JUMO 902030 gives specifiers a highly configurable, field-proven RTD platform built in corrosion-resistant 1.4571 stainless steel. Its spring-loaded internal connection and reliable sealing for both vacuum and overpressure duty make it a dependable choice for continuous industrial monitoring throughout Oman’s process and food-manufacturing sectors.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the JUMO 902030 screw-in RTD probe to industrial buyers across the Sultanate of Oman and the wider GCC. Every unit shipped from our regional stock is a genuine JUMO instrument, backed by full manufacturer warranty, metrological registration, and in-country technical support — giving facility engineers in Muscat, Sohar, and Salalah confidence in authentic instrumentation rather than uncertain grey-market imports.

Measurement Principle

The JUMO 902030 measures temperature via the resistance thermometry principle: a platinum sensing element changes electrical resistance in a precise, repeatable relationship with temperature, in accordance with IEC 60751. As the probe’s screw-in tip is inserted directly into the process medium, the platinum element absorbs heat and its resistance rises correspondingly, allowing the connected head transmitter or control system to derive an accurate, standards-based temperature reading. Because platinum RTDs offer excellent long-term stability compared with thermocouples, the 902030 is specified wherever repeatable, drift-resistant temperature feedback is required over years of continuous plant operation.

The 902030’s fast-response design is optimized for rapid measurement in air as well as liquid media, while its reliable internal sealing maintains accuracy under both vacuum and overpressure conditions — a combination that keeps the sensor performing consistently across variable process states without introducing pressure drop or contamination risk to the measured medium. This solid-state RTD sensing approach, with no moving parts, is why the 902030 requires minimal maintenance over its service life once correctly installed.

Engineering Design of the JUMO 902030

The JUMO 902030 is constructed from stainless steel 1.4571 throughout its sheath and connection head, screwing directly into the process via a spring-mounted threaded connection that maintains constant contact pressure between the sensing tip and the base of the installation point. Sheath diameters of 6, 7, or 8 mm are available, paired with insertion lengths ranging from 50 mm to 500 mm, giving specifiers the flexibility to match probe geometry precisely to vessel wall thickness or pipe diameter without ordering a custom part.

The Form J terminal head houses the wiring terminals for 3-wire or 4-wire connection and can optionally accept a head-mounted transmitter for direct 4–20 mA conversion at the measurement point, reducing cable-run signal degradation on larger sites. With an IP65 ingress protection rating and metrological registration plus SIL and PL functional-safety approvals, the 902030 is built to satisfy both general industrial duty and regulated process environments where documented compliance is part of the procurement specification.

Key Features

The JUMO 902030 screw-in RTD probe combines flexible configuration options with the build quality that JUMO temperature instrumentation is known for across regional industry.

• Pt100, Pt500, or Pt1000 sensing elements in Class 1 or Class 2 accuracy give specifiers precise control over cost and measurement tolerance.
• Sheath diameters of 6, 7, or 8 mm and insertion lengths from 50 to 500 mm allow the JUMO 902030 to be matched exactly to the installation geometry.
• Corrosion-resistant 1.4571 stainless steel construction withstands humid coastal and industrial atmospheres common across Gulf facilities.
• A spring-mounted screw-in connection maintains constant sensing-tip contact pressure for stable, repeatable readings.
• Reliable sealing for both vacuum and overpressure applications extends the probe’s suitability across variable process conditions.
• An optional Form J head-mounted transmitter converts the RTD signal to a 4–20 mA output directly at the sensor for simplified control-system integration.
• Metrological registration together with SIL and PL functional-safety approvals supports use in regulated and safety-instrumented systems.
• Fast response in both air and liquid media makes the 902030 suitable for dynamic thermostat-bath and process-monitoring duties.

Industrial Applications

The JUMO 902030 is widely deployed in mechanical engineering, gearbox and drivetrain manufacturing, thermostat baths, and heating and oven construction, as well as air-conditioning and refrigeration systems throughout the region. Food and beverage processors across Oman rely on its corrosion-resistant stainless steel construction and fast response time for pasteurization, cooking, and cold-chain monitoring, while district cooling plants and commercial HVAC systems in Muscat specify the 902030 wherever a configurable, screw-in RTD is needed on chilled-water and process-air loops. Meat-processing facilities and light-industrial manufacturers operating within Oman’s growing industrial zones also favor the 902030 for its metrological registration and documented accuracy class, both of which support internal quality and food-safety compliance programs.

With regional stock and engineering support in Muscat, Seven Star LLC distributes the 902030 screw-in RTD probe to contractors, OEMs, and plant operators throughout Oman, the wider GCC, and specifically within the Sohar and Salalah economic zones, where manufacturing, food processing, and logistics facilities depend on genuine, locally stocked instrumentation and responsive after-sales support. Hospitality developments and hospital complexes across Muscat also incorporate 902030-class RTD probes into their kitchen, laundry, and building-utility systems, where accurate and stable temperature monitoring directly supports operational safety and energy efficiency. Sourcing through Seven Star LLC ensures customers receive authentic JUMO hardware with full warranty coverage rather than uncertain third-party imports.
