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.

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.
