Programmer can be connected directly to a USB port where it takes the operational energy so the additional power supply is not required. The transmitter is configurated using multi purpose configurationsoftware MekuWin. MekuWin is compatible with all Nokeval’s intelligent instruments. The wide operational temperature range -40..+85°C makes it possible to use the transmitter almost in any industrial enviroment. Transmitter has exeptionally good input and output resolution (24 bit input and 16 bit output). Excellent stability guarantees longterm accuracy. If needed, the transmitter can be calibrated in one or two points. Transmitter has been fully tested in our EMC-laboratory in Nokia to be as immune as possible to different type of distortions. The transmitter exceeds the required standards and is CE-approved. Configurating is made using additional USB-port connected programmer. The programmer is connected using crocodile clips to transmitters out putconnectors. Settings are done using easy and versatile programming software MekuWin. It is possible to download MekuWin software from www.nokeval.com. Field enclosure is available with or without Pt100 sensor (option). Enclosure size is 58 x 65 x 35 mm (WHD), IP65, gland(s) PG11. Transmitter can be installed to DIN rail (35 mm) by using HTB-DIN bracket. Programming is fast and easy using MekuWin cofiguration program. Programmer takes it’s power from USB connectoin from PC.
