Dissolved Oxygen Transmitters

The DO500 4-20mA loop-powered transmitters allow a galvanic DO sensor signal to be sent as a 4-20mA loop (DO6400 series, 971651). The built-in electronic circuit converts the millivolt raw sensor signal to a 4-20mA output. The display can be programmed to read % saturation or mg/mL or ppm DO. Temperature is also visible on the display via a Pt100 temperature sensor (automatic) or manual input. Salinity and pressure compensation are via user input. A separate 12-36V DC power supply (user supplied) is required to power each DO500.

DOMA-10 and DOMA-20, are very basic 4-20mA loop-powered transmitters which allow DO1200/H sensor signal to be sent as a 4-20mA loop. The built-in electronic circuit converts the DO1200/H sensor's millivolt signal to a 4-20mA signal. Two ranges are available: DOMA-10 (0-100% = 4-20mA) and DOMA-20 (0-200% = 4-20mA). A separate 12-36V DC power supply (user supplied) is required to power each DOMA.
