供应可编程两线制变送器/智能变送器 深圳供应商代理销售德国原装进口Roessel可编程两线制变送器,型号:Model RT Programmable Transmitter Type RT Two-wire transmitter for mounting in sensor-heads, field-housings or control panels. Transmitters convert the low-level ** from thermocouple or resistance thermometer into a high-level standard **. The non-linear input from temperature sensors is converted into a temperature- or EMF - linear output **, 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.
