Programmable two-wire transmitter for use in measurement and control systems. Transmitters convert the low-level signal from thermocoupples or resistance thermometers into a high-level standard signal. The non-linear input from temperature sensors is converted into a temerature- or EMF-linear output signal, depending on programming, 4... 20mA.
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.
