ROESSEL has many years of experience, state-of-the-art manufacturing plants combined with a comprehensive quality control system.

This assures the reliability and accuracy of ROESSEL sensors.

The ROESSEL subsidiary CENTROCAL – a consulting, testing and calibration center for temperature measurement – calibrates temperature sensors at highest accuracy and with state-of-the-art equipment.

ROESSEL transmitters are manufactured with state-of-the-art components using SMD technology. They are extremely resistant and meet highest demands. They can withstand harshest ambient conditions, and can also be supplied with ATEX certification. Resistivity against radio frequency interference acc. to industrial NAMUR standards is met.

Programmable transmitters reduce the number of measuring ranges, like with analog transmitters, to only one design. Analog transmitters are supplied with potentiometer for calibration point of zero and span, alternatively without potentiometer for highest requirements.

Our transmitters are supplied in intrinsically safe design acc. ATEX in EEx ia / ib II c T6. The electromagnetic compatibillity is acc. standard of industry to EN 50081 and EN 50082.

ROESSEL transmitters are manufactured in different designs. Prefered is the mounting in the lid of the connection head or directly on the measuring insert. Designs for field housing are also available as well as rail-mounted housing in control cabinets                                   

Model with potentiometer

This model is designed for direct connection of resistance thermometers. The transmitter converts the signal from the temperature sensor into a standard signal of 4 … 20 mA.

The AT-W transmitter is available in intrinsically safe design EEx ia II C T6 according to EN 50020.

Model with potentiometer

This model is designed for direct connection of resistance thermometers and thermocpuples. The design for thermocouples has a built-in reference junction and is available for a multitude of thermocouple types. The transmitter converts the signal from the temperature sensor into a standard signal of 4 … 20 mA (current loop). Depending on the design the signal is displayed temperature- linear (resistance thermometer) or EMF-linear (thermocouple). We supply transmitters with potentiometer for calibration point of zero and span.

The programmable two-wire transmitter combines all the advantages of analog 2-wire transmitters with being in addition programmable. Using a standard PC and an interface adapter (RKA) all important parameters like measuring range, sensor type, etc. can be preset. Thus only one design is needed for all applications. In addition the programmable transmitters possess a galvanic insulation between input and output signal.

Two-wire transmitter for mounting in sensor-heads, field-housings or control panels.

Transmitters convert the low-level signal from thermocouple or resistance thermometer into a high-level standard signal. The non-linear input from temperature sensors is converted into a temperature- or EMF - linear output signal, depending on programming, of 4... 20mA.

The microcomputer-controlled system reduces the type and range variety, usual with analog transmitters, to only one model. Significant lowered inventory costs, universal use, short change - over and shut - down times are the advantages.

For maximum operational safety and reliability in harsh ambient conditions like vibrations no mechanical components (potentiometers) are involved whereever possible. Extensive calculations like drift/offset compensation, linearisation, limit comparison are done ''on site'' which means immedialely close to the sensor.

For the transmitter configuration a RS232-interface adapter is available. A comfortable user-friendly software in Windows - technique is used for programming communication and operation. Standard parameters are available via the RS232-interface as well as the measuring value, limits, cool joint temperature and so on without affecting the analog output of 4 to 20 mA.

HART-Communication Two-wire transmitter for mounting in sensor-heads, field-housings or control panels.

Transmitters convert the low-level signal from thermocouple or resistance thermometer into a high-level standard signal. The non-linear input from temerature sensors is converted into a temperature or EMF - linear output signal, depending on programming, of 4 ... 20mA. The transmitter uses the HART - protocol and frequency shift keying on the 4 - 20 mA current output loop.

This system ensures either a multi - drop communication with up to 15 units or full operation as a - wire transmitter in a 4 - 20 mA current loop.

The microcomputer-controlled system reduces the type and range variety, usual with analog trasmitters, to only one modell. Significant lowered inventory costs, universal use, short change-over and shut-down times are the advantages.

Extensive calculations like drift/offset compensation, linearisation, limit comparison are done `on site`, which means immediatly close to the sensor. For the transmitter configuration a RS232-interface is available. A comfortable user-friendly software is used for programming communication and operation. Standard parameters available via the RS232-interface as well as p.e. the measuring value, limits, cool joint temperature etc. withhout affecting the analog output of 4 ... 20 mA.

Our model RT-R is especially designed for use in small and wall-mounted housings. The compact size of the rail-mounted housing (only 22.5 mm width) allows a high packing density in the mostly rare cabinet space. The small height of 104 mm makes a double-stage mounting possible. In most cases an extension of existing systems is easy to realise.
