sales@nokeval.com www.nokeval.com Yrittäjäkatu 12 37100 Nokia, Finland One or two channel 2-wire transmitters RTB231 and RT232 for RTD sensors • One or two channels • RTD sensors Pt100, Ni100, Cu10 • 2 wire 4-20 mA output • Freely scalable measuring range • 2 point calibration option • Operating temperature range -40...+85°C • Accuracy < 0.05% from reading +0.1°C • Excellent stability One and two channel RTB series transmitters have been designed for different type RTD sensors with two wire 4-20 mA output. Channels are completely isolated from each other. Transmitters have exceptionally good input and output resolution, 24 bit input and 16 bit output. Excellent stability guarantees long term accuracy. If needed, the transmitter can be calibrated in one or two points together with sensors. The wide operational temperature range -40..+85°C makes it possible to use almost in any industrial enviroment. 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. Transmitters can be configurated using multi purpose configuration software MekuWin (free). MekuWin is compatible with all Nokeval’s intelligent instruments. Transmitters are delivered according to ordered measuring range. RTD sensors 3 or 4 wire connections Configurating is made using USB-port connected HTP-Prog programmer that is connected to transmitters output connectors. HTB-Prog programmer can program also headmounting transmitter HTB230. Transmitters delivered with ordered measuring range or settings can be done later using easy and versatile programming software MekuWin. It is possible to download MekuWin software from www.nokeval.com. Power supply
