JUMO Wtrans T Wireless RTD Temperature Probe

Name: JUMO Wtrans T Wireless RTD Probe – Datasheet & Price Quote
Brand: JUMO

Description

Overview

JUMO Wtrans T is a battery-powered wireless RTD temperature probe that acquires temperatures across an operating range of -30 to +260°C or -200 to +600°C, depending on ordered configuration, and transmits the measured value wirelessly to the receiver of the JUMO Wtrans measuring system. Available as an insertion or mineral-insulated RTD probe with fixed or flexible protection tubes, the JUMO Wtrans T makes mobile or stationary temperature measurement possible without any wiring work between the sensing point and the receiver.

With fast quotation turnaround and technical support, Seven Star LLC proudly supplies the JUMO Wtrans T to refineries, process plants, and instrumentation teams across Oman and the GCC. Customers purchasing through Seven Star LLC receive a formal quotation, the manufacturer datasheet, and technical support based in the Sultanate of Oman.

Measurement Principle

The JUMO Wtrans T uses a Pt1000 resistance temperature detector connected in a three-wire circuit to sense process temperature, following the standard RTD principle in which the platinum sensing element’s electrical resistance increases in a well-characterized, repeatable way as temperature rises. The probe’s onboard electronics digitize this resistance measurement, convert it to a calibrated temperature value, and transmit the reading – along with encoded transmitter identification and battery status – wirelessly to a paired JUMO Wtrans universal receiver at a configurable transmission interval of 1 to 3600 seconds.

Because the entire sensing and radio transmission chain is self-contained within the probe assembly, the JUMO Wtrans T eliminates the cable runs and signal wiring that would otherwise be required between a remote or hard-to-reach measuring point and the control system, while the wireless link itself operates fail-safe on the 868.4 MHz or 915 MHz ISM bands, chosen for their resistance to external interference even in rough industrial environments.

Engineering Design of the JUMO Wtrans T

The JUMO Wtrans T is built around a stainless steel protection tube housing the Pt1000 sensor per DIN EN 60751 Class A, available with flat, angled, or centrally aligned probe tips and insertion lengths from 30 to 10,000 mm to suit a wide range of installation geometries. The transmitter housing itself is molded from vibration-resistant, oil- and acid-resistant PEI (polyetherimide) and rated IP67, powered by a 3.6 V lithium battery that also supports the case’s ambient operating range of -30 to +85°C or -25 to +125°C depending on variant.

For hazardous-area installations, the JUMO Wtrans T is available with ATEX approval (basic types 902930/15, /17, and /55), allowing the transmitter to be installed directly in potentially explosive areas up to Zone 0 while the receiver remains outside the Ex zone – the wireless link avoiding the costly cable installations, protection barriers, or supply isolators that a wired intrinsically safe loop would otherwise require. Variants with an extension tube or an M12 × 1 plug connector are also available for connecting external Pt1000 RTD probes, and the Ex variant with M12 connector is always delivered with an approved JUMO RTD probe with PTFE connecting cable.

Key Features

The JUMO Wtrans T combines robust wireless RTD measurement with configuration flexibility for demanding mobile and hazardous-area applications. Key characteristics include:

Operating temperature range of -30 to +260°C or -200 to +600°C depending on configuration.
Pt1000 RTD sensor per DIN EN 60751 Class A in a three-wire circuit.
Wireless transmission at 868.4 MHz (300 m range) or 915 MHz (100 m range) to a JUMO Wtrans receiver.
Configurable transmission interval from 1 to 3600 seconds.
Available with ATEX approval for direct installation in explosive atmospheres up to Zone 0.
Vibration-resistant, oil- and acid-resistant PEI housing rated IP67.
Insertion lengths from 30 to 10,000 mm with flat, angled, or centrally aligned probe tips.
Optional extension tube or M12 × 1 plug connection for external RTD probes.

Industrial Applications

The JUMO Wtrans T is deployed wherever cable installation to a temperature measuring point is impractical, hazardous, or prohibitively expensive, including hard-to-reach plant locations, mobile and rotating equipment, and installations within potentially explosive atmospheres where a wired intrinsically safe loop would otherwise be required. Its wide -200 to +600°C range and mineral-insulated probe option extend its suitability to demanding high-temperature process monitoring as well as cryogenic and low-temperature applications.

With engineering support in Muscat, Seven Star LLC supplies the JUMO Wtrans T to refineries, gas processing facilities, and industrial plants throughout Oman and the wider GCC, including operations within the Sohar and Salalah economic zones. Regional customers benefit from hazardous-area installation guidance and access to JUMO’s engineering documentation through Seven Star LLC’s technical instrumentation division.

About brand

Temperature measurement is the origin of JUMO, founded in 1948 in Fulda, Germany, as a maker of glass thermometers. Today the catalog covers sensors and transmitters for temperature, pressure, level and liquid analysis, plus controllers and recorders. Seven Star LLC lists JUMO RTD probes, pressure and differential pressure transmitters, pH, conductivity, turbidity and dissolved oxygen instruments, and sources them for plants in Oman.

JUMO product families listed

JUMO uses family names that recur across the catalog:

dTRANS: transmitters, including dTRANS T01 and T100 for temperature, dTRANS p02 DELTA for differential pressure, and dTRANS pH 02 and CR 02 for liquid analysis
Wtrans: wireless probes and transmitters, such as Wtrans T for RTD temperature and Wtrans p for pressure
digiLine and ecoLine: digital and optical analysis sensors, for example the digiLine O-DO S10 dissolved oxygen sensor and the ecoLine NTU turbidity sensor
NESOS: float-based level transmitters and switches
RTD temperature probes: screw-in types such as 902030 and mineral-insulated designs

Where JUMO sensors are used

JUMO sensors and transmitters are typical of food and beverage lines, water and wastewater treatment, pharmaceutical utilities, heating and cooling systems, and packaged machinery supplied to the GCC by European builders. Many requests are for a like-for-like replacement of a probe fitted by the machine maker, where length, thread and connector have to match exactly.

Ordering JUMO parts: what we need

JUMO identifies each product group by a six-digit type number, such as 902030, followed by an order code that fixes the options. The label of the delivered item normally carries a part number as well. Send whichever you have, ideally both, or a photo of the label. For JUMO temperature probes add insertion length, diameter, process connection, sensor type and wiring. For JUMO pressure sensors state range, output, process connection and electrical connector. For analysis sensors name the transmitter they connect to and the cable length.
