LMI Controllers

pH pulse output controller

Use with flow and level switches to stop pump in case of blockage or chemical exhaustion
Pulse output models feature three point proportional control for precise measurements
These wall-mount controllers feature either on/ off or pulse output with optional isolated 4 to 20 mA output. Compatible electronic diaphragm pumps are listed below to simplify for system' s component selection.
All controllers accept pH probes with 1 k© Pt RTD ATC — order from pages 662-669. Controller also accepts contact closures from flow and level switches to stop pump operation in the event of blockage or chemical exhaustion. Remote on/ off enables use with another control system.
Use the three-point proportional control capability found with pulse output controllers ( 57300-20, -30) to define two slopes of flow rate vs. pH. This feature is ideal for either fine-tuning the pump output when conditions require rapid chemical addition.

Controllers with pulse output are compatible with 74501-, 07100-, and 74500-series pumps--no need for a separate timer to " translate" pulse signal.
