The JUMO dTRANS O2 01 2-wire transmitter serves to measure dissolved oxygen in watery solutions. It provides an electrically isolated output signal 4 ... 20mA according to the oxygen content. The device can be configured via a setup program or an optionally available connection and operating unit. The temperature of themedium to be measured can be detected and further processed (from the standard version also as 2-wire signal 4 ... 20mA) via a Pt 1000 in the 2-wire transmitter.
Measurements are carried out with an electrochemical probe covered by a membrane. The microprocessor circuit installed in the 2-wire transmitter considers the factors: temperature, air pressure and salinity (salt content).
The probe is designed as a module and can be easily maintained and replaced.
