 | BL 981411 PH Mini Controller | | |
| - Easy to handle
- Fire retardant casing
- Selectable overdose protection system
- Splash resistant cover
The BL 981411 pH controller has been designed for easy, affordable installation in tight spaces, ideal for simple and effective process control. The unit is provided with high impedance pH input and can be used with any pH electrode with standard BNC connector. Measurements are clearly displayed on the LCD, while the status LED indicates operating mode. BL 981411 is also provided with a dosing relay. Selecting acid dosing, will cause the relay to activate when the measurement is higher than the set point. If the basic dosing is selected, the relay is activated when the reading falls below the set point. Set point adjustment (from 0 to 14 pH) and calibration procedures are easily performed with trimmers on the front panel. Users can choose from automatic or manual dosing modes with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. An overtime control system advises users when the relay is active too long, to help prevent overdosing. Order Information:

- Selectable overdose protection system
- Splash resistant cover
BL 983314 is a simple to operate resistivity controller designed for ultra pure water, reverse osmosis, and water conditioning applications. The BL 983314 resistivity controller is also ideal for continuous monitoring of process solutions. Set point and calibration are manually adjusted with a trimmer and the alarm relay allows for simple control. Readings are automatically temperature compensated, with three different coefficients (β=2.4, 3.5 or 4.5 %/°C). The alarm contact can be used for connection to an alarm, pump, solenoid or dosing system. The relay contact is open when readings are higher than the set point, while for measurements lower than set point, the relay contact is closed. The Hysteresis is typically 0.20 MW/cm from the set point. Measurements are displayed on the LCD and the multicolored LED continuously indicates if the controller is in measurement, dosing or alarm mode. Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. The overtime control system advises users when the relay is active for too long, helping to prevent over-dosage. Order Information:
