A conductivity transmitter that achieves both high precision and reliability.
The conductivity transmitters DO9766T-R1 (wall-mounted type) and DO9786T-R1 (panel-mounted type) correct the output of the conductivity electrode for temperature and convert it into an insulated 4-20mA analog signal from the input circuit of the electrode, with scaling capabilities. In addition to the analog output, they are equipped with two relay outputs that can be set with a delay of up to 250 seconds. The large LCD on the front displays the process measurement values under normal conditions and the set parameters during configuration. Thanks to high-quality product design and the use of carefully selected components, they enable long-term, high-precision, and reliable measurements. They are used in combination with separately sold conductivity electrodes and temperature probes (Pt100Ω/0℃). ▼ DC4-20mA output conductivity meter ▼ Relay output (delay setting available)
