Martens, a member of the GHM Group, has introduced the first digital safety temperature limiter for thermal industries. The Safety-TL4896 is the first to offer a switch panel installation.
Jan Grobler, Managing Director of GHM Messtechnik in South Africa commented “The Safety-TL4896 is innovation at its best, offering users a host of cost and resource savings. A key innovation is that it is the first digital safety temperature limiter available worldwide. The limiter complies with all European Standard safety regulations. It has a reaction time of 0.5 seconds, shutting down the system if it detects an unsafe condition and will ensure continuous operating with the added feature of a pre-alarm for temperature fluctuation . The front LED alarm and the background light of the display illuminate showing the cause as plain text on the display. The Safety-TL 4896 eliminates the need for any other measuring instrumentation in the systems chain”.
The Safety-TL4896 satisfies all DIN EN14597 requirements and has been issued with a SIL2 certificate.
- The Safety-TL operates as a direct indicator, because it is installed in the control panel instead of on the top-hat rail. Therefore, the additional “indicator” element can be omitted.
- With the integrated analogue output for the temperature signal, an additional measuring chain for the measuring signal for the PLC or SCADA world can also be omitted.
- Another advantage is the execution of the reset function directly on the device. No additional control element is needed.
- Configuration of the Safety-TL takes place directly via the front-side buttons in combination with the graphic display – without any additional programming software.
The advantage of the pre-alarm, which triggers an (preliminary) alarm before the limit value is reached, is that a potential shut-down of the system can be avoided. This makes it is possible to intervene and take corrective action an early stage.
Grobler concluded “The Safety-TL4896 is a world first for the thermal industries and enhances a plants compliance and obligations to local regulations”.
