JUMO safetyM STB/STW Ex

The compact and user configurable JUMO safetyM STB/STW Ex can now also enable early and reliable detection of risks in Ex-areas which could potentially result in personal injuries, environmental damage, or destruction of the production plant and production materials.

The primary task of safety temperature limiters is to reliably monitor thermal processes and to switch plants to a safe operating status in the event of malfunctions. Along with the existing approvals according to DIN 14597, SIL 3, PL e (Performance Level), DNV, the device also has approval according to ATEX and can therefore also be used for measurements in Ex areas. However, the device itself has to be installed outside the Ex area.

The inputs are intrinsically safe [Ex ia] so that relevant probes can be connected directly. Barriers are no longer required. The device is also certified according to DIN EN 50495 and DIN EN ISO 80079-37 as an ignition source monitoring device (iPL 2) as specified in the ATEX directive and can be used to monitor potentially explosive atmospheres containing gas or dust. The device concept also meets the stringent requirements of DIN EN 61508 and DIN EN 13849. The 1oo2D structure ensures reliable detection of faults, meaning that the device concept can also be used for applications subject to the new Machinery Directive 2006/42/EC.

Along with the keypad, the clear and well-structured backlight display with plain text provides quick and straightforward configuration directly on the device. The clear menu structure ensures easy operation, which in turn shortens startup times. All safety relevant process values are displayed and the most important functions are shown by simple pictograms.

Working with JUMO

JUMO GmbH & Co. KG is one of the leading global supplier of components and systems for individual sensor like pressure transmitter and automation solutions. As a high-tech company Jumo distinguishes itself by a particularly high degree of innovation, above-average production depth, and a broad product range.
