The integration of sensor data into higher-level networks is a key requirement of modern process automation. Intelligent temperature sensors are increasingly taking over measuring, switching and display tasks within a single device. Such systems are used in the food industry, mechanical engineering and chemical process technology, where they contribute to process reliability and simplify integration into existing control systems.
Integration through Single Pair Ethernet and IO-Link
At the all about automation trade fair in Hamburg (2 to 3 June 2026, Hall B6, Booth 313), JUMO will present technological approaches to industrial digitalization. The focus is on the implementation of communication interfaces such as Single Pair Ethernet (SPE) and IO-Link in sensor technology. These standards enable continuous data transmission from the control level down to the field level. A key technical feature of SPE technology is the ability to transmit sensor data directly into cloud infrastructures via TCP/IP without the use of additional gateways or protocol converters, thereby reducing the complexity of the network architecture.
Technical specifications of the temperature sensor technology
One application example for this networking technology is the JUMO DELOS T02 temperature sensor. The system combines continuous temperature measurement with an integrated display and programmable switching functions. The device’s measurement accuracy is specified at up to 0.3 Kelvin. For parameterization and maintenance tasks, the sensor features wireless transmission paths via Bluetooth and NFC in addition to wired interfaces. Configuration can therefore be carried out wirelessly using mobile devices. The housing is mechanically robust and meets the requirements of UL certification and H2 readiness, making the system suitable for hydrogen applications and critical process environments.
Expansion of plant control and safety technology
In addition to the sensor level, process automation also requires hardware-coordinated control and safety components. In this segment, automation systems such as the JUMO diraTRON DR100 controller and the safety and control solutions of the JUMO safetyM series are used to implement networked plant architectures. The physical and network-related foundations of industrial data transmission will also be addressed during the trade fair in a specialist presentation by graduate engineer Manfred Walter on 3 June 2026 (12:40 p.m. to 1:00 p.m., Talk Lounge, Booth 300). The presentation, titled “Intelligent Sensors with Single Pair Ethernet,” will cover the implementation of these communication standards in industry.
Additional context: This section details technical specifications and competitive comparisons that were not included in the original product announcement
In the field of intelligent temperature sensor technology with digital interfaces, solutions from manufacturers such as JUMO compete with devices from Endress+Hauser, ifm electronic and Turck. A key distinguishing feature of current sensor generations is native support for Single Pair Ethernet (SPE) according to the IEEE 802.3cg standard. While conventional IO-Link sensors rely on master modules for connection to IP-based networks, SPE enables direct IP communication at the sensor node. Transmission rates of 10 Mbit/s over cable lengths of up to 1,000 meters (10BASE-T1L) are achieved. The combination of SPE, wireless short-range diagnostics (Bluetooth/NFC) and a measurement accuracy of 0.3 Kelvin positions devices such as the DELOS T02 in the segment of high-precision process sensor technology. Many competitors in the same application field currently rely primarily on IO-Link V1.1, which supports established topologies but requires additional translation hardware at the control level for direct IT/OT convergence.
