HIGH-DENSITY TEMPERATURE MONITORING VIA ETHERNET WITH TCS
M
oore Industries has announced a significant update to its TCS Temperature Concentrator System, enhancing both efficiency and versatility.
The latest development introduces the HES HART-to- Ethernet Gateway System, which integrates seamlessly with the company’s 16-channel TCM Temperature Concentrator Modules. This advancement enables Ethernet-based communication within the TCS. The HES is available in single- channel or four-channel configurations and can connect with up to two TCMs per channel. As a result, up to eight TCMs can communicate with a single HES, allowing as many as 128 temperature signals to be transmitted over an Ethernet link to a MODBUS/TCP-based host.
This update significantly expands monitoring capabilities, enabling users to access temperature readings across an industrial Ethernet backbone via any MODBUS/TCP or HART-IP host. In addition, the HES features an embedded web server, allowing temperature points to be viewed and monitored through a standard web browser. The system can also communicate with up to sixteen HART devices per channel, meaning that even when two TCMs are connected, capacity remains for a further fourteen HART devices.
or replace competitors’ analysers, we know the true cost of unreliability.”
Good examples of the ways in which product development at Signal has been driven by customers include detachable screens, remote communications and portable VOC analysers.
All of Signal’s latest analysers feature detachable screens. This is because gas analysis rarely takes place in a clean, tidy, perfect environment. Often, analysers have to be installed in locations with difficult access. This could be in an ATEX enclosure, in a vehicle exhaust test cell, on a raised gantry around a stack, in a combustion test rig, or where safe working cannot be guaranteed. In all these applications the ability to operate the analyser from up to 50 metres away offers enormous advantages.
The development team at Signal noticed that the ability to check measurements remotely from anywhere and at any time would be a particular advantage. For example, it would be particularly advantageous to be able to monitor readings overnight and during weekends. To achieve this, Signal’s latest analysers each have their own IP address, and are compatible with 3G, 4G, GPRS, Bluetooth,

Wi-Fi and satellite communications. A further example of a useful development to improve gas measurement reliability is a portable gas analyser. “Yes, we would obviously have developed portable analysers anyway,” Clements concedes, “Customers need them for discontinuous measurements and multi-site operation, but our portable FIDs provide an excellent back-up to fixed analysers, and can also be rushed in to maintain the continuity of VOC monitoring when continuous monitors are down for any reason.”
Continuing this theme, Signal recently developed a portable version of its fixed VOC analysers. The recently launched S4 SOLAR XPLORE is a portable heated FID VOC analyser with most of the capabilities of its fixed siblings.
Summarising Clements says: “The cost of unreliable gas measurement can be incredibly high, representing an unacceptable risk for most businesses. For that reason, we invest heavily in developing analysers and ancillary equipment that enhance Signal’s reputation as a reliable partner.”

The TCM Temperature Concentrator Module converts signal inputs into the standard HART protocol, allowing the HES to poll each module using a device-specific command. This enables all 16 channel values to be transmitted in a single HART message packet, improving both throughput and response time. Designed to reduce costs and improve operational efficiency, the TCS system is suitable for both general-purpose and hazardous environments. Each TCM module features 16 I/O channels that can be configured for multiple input types and converted into the HART digital protocol, enabling long-distance transmission over Ethernet via the HES.
Supporting HART, MODBUS RTU, MODBUS/TCP and HART-IP protocols, the TCS Temperature Concentrator System integrates easily with existing monitoring and control infrastructures. It is also intrinsically safe approved for hazardous areas where numerous temperature points are present, offering a high-density monitoring solution that reduces the need for dedicated transmitters and extensive wiring.
