BL931700 pH MINI CONTROLLER WITH 4-20mA RECORDER OUTPUT
|
BL931700 mini pH controller has been designed for easy,
affordable installation in tight spaces to perform simple yet effective
process control. Thanks to its compact size, BL931700 can be installed right next to tanks or vats. This versatile controller is ideal for a wide variety of applications, such as textiles, papers, photographic solutions, plating baths, chemicals and water treatment. BL931700 is provided with a selectable setpoint for acid or basic dosage. Measurements are directly aquired from a pH electrode in the range from 0 to 14 with a 0.01 pH resolution. Accuracy is ensured by the 2 point calibration, performed manually through trimmers on the front panel. You can also choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits you to enable or disable the dosing relay according to your need. The overtime control system advises you when the relay is active for too long, helping to prevent overdosing. In addition, this model features a 4-20mA analog output for recorder connection. Two models are available, with different power supply input at 115/230 VAC or 12 VDC. BL931700-0 is supplied complete with mounting brackets, transparent cover, 12 Vdc power adapter and instructions. BL931700-1 is supplied complete with mounting brackets, transparent cover and instructions. |
