DO Transmitters with Hart Protocol Interface
Model OBM-165H (low concentration)
Model OBM-167H
The Model OBM-165H (Low-Concentration Measurement) and Model OBM-167H are 2-wire type (24VDC power supply) dissolved oxygen transmitters housed in robust, cast aluminium enclosures suitable for field installation. These models are equipped with a wide range of useful features, such as HART communication interface.
- HART communication (version 7) supports the transmission of digital data such as DO measured value, temperature measured value, and equipment
status commands. - Freely adjustable transmission output range.
- When maintenance mode is enabled, the “ST-BY” indication is on. In maintenance mode, the output signal is held at the value which was set before the
mode was enabled. The instrument can also be configured to automatically
return to measurement mode. This feature is especially useful when the instrument is inadvertently left in maintenance mode. - The instrument is equipped with a burn-out function. When the self-diagnostics function detects an error in the measurement system, such as a computer error or
the failure of the temperature compensation resistor, the burn-out function provides notification of the problem by causing the transmission output to go off-scale
(upper or lower limit). - The instrument automatically judges the quality of electrode characteristics during calibration, and provides diagnostic information in the form of error
messages.
