pH/ORP (REDOX) Transmitter with Hart Protocol Communication Interface Model HBM-165H
Transmitter for pH/ORP measurement suitable for field installation. The transmitter features a Hart communication interface using a 2 wire, 24 VDC circuit. The transmitter also has a robost cast-aluminium case, digital display and a wide range of other useful features. Measurement of pH or ORP is available using the appropriate electrode
- Data on up to 5 calibration solutions is stored in memory. This combined with the built-in temperature sensor in the electrode allows automatic recognition of calibration solutions without needing user input. In addition, an automatic stability judgment function ensures accurate calibration, free from user errors.
- The transmitter judges the electrode quality when measuring calibration or checking solution.
- Electrode glass breakage detection.
- In addition to automatic temperature compensation, the transmitter also allows the user to set the temperature compensation coefficient. This allows measurement in applications such as boiler feed water control etc.. The transmitter is also compatible with electrodes that have non-standard temperature sensors (ie. 10 KΩ @ 25°C) or no temperature sensor.
- Maintenance mode feature holds the measured value immediately before switching into maintenance to prevent disruption to process control during maintenance activities. In addition, automatic return to measurement mode can be set in case operator forgets to manually switch back to measurement mode after performing maintenance.
- Hart communication interface.
