The Jumo dTRANS T05 represents the next generation of 2-wire temperature transmitters that introduce a USB interface for programming. The devices are available as head transmitters, for installation in a DIN terminal head form B (Jumo dTRANS T05B), as well as for mounting rail installations (Jumo dTRANS T05T). The USB interface allows technicians to use a PC or notebook for easy and convenient programming. This way, the transmitter can be programmed with the setup program and a mini USB cable without an additional auxiliary power connection or a special interface. The sensor wiring can be quickly checked with the integrated online display of process values in the setup program. The drag pointer function integrated in the transmitter provides information about the thermal limit states. This allows the setup program to query the minimum and maximum process temperatures that are important for plant optimization.

Both versions have a universal measurement input for all common RTD temperature probes or thermocouples. Resistance transmitters and voltage signals (0 to 1 V) can also be connected. When using a resistance transmitter or RTD temperature probe, it is possible to connect the sensor in a 2-wire, 3-wire, or 4-wire circuit. The measurement input with 22-bit resolution guarantees a high measuring accuracy when conditioning the sensor signal. The electrically isolated current output (4 to 20 mA) with 1 µA resolution ensures good transmission behavior with high insulation strength.

Safety temperature limiters/monitors
The compact and freely-configurable temperature limiters/monitors safetyM STB/STW Ex with ATEX approval can now also be used for the reliable and early detection of potential dangers in the Ex zone that could lead to personal injuries, damage to the environment, or destruction of production systems and industrial goods. The instruments are available in versions Ex II (1) G [Ex ia Ga] IIC and Ex II (1) D [Ex ia Da] IIIC. The primary tasks of safety temperature limiters are to monitor thermal processes and to bring systems to a safe operating state in the event of a malfunction.

The inputs are intrinsically safe [Ex ia] so that the corresponding probes can be directly connected. Therefore the use of a barrier is no longer necessary. The instrument is also certified according to DIN EN 50495 and DIN EN 13463-6 as an ignition source monitor (iPL 2) according to the ATEX directive.
The new safety temperature limiter/monitor can be used to monitor critical processes in potentially explosive gas and dust atmospheres. The bright, clearly structured display with clear text display and background lighting ensures − in connection with the keyboard − a fast and uncomplicated configuration directly on the device. A mini-USB connector is available at the front for the configuration with a PC or laptop. LEDs indicate whether the system is operating without errors or whether a pre-alarm or limit value alarm has been triggered.
