The BL932700 is a compact,ORP process controller designed for applications where space or cost is important. The device may be used with any ORP electrode with a standard BNC connector. It's adjustable dosing relay may be configured to dose above or below a user programmable mV setpoint. Users may choose from automatic or manual dosing modes allowing for easy maintenance and troubleshooting.
The BL932700 features a dosing relay which may be configured to dose above or below a user programmable mV setpoint.
The mini controller may be programmed to deactivate a valve, pump, or connected device if its activation continues over a selected time; adjustable from 5 to 30 minutes.
With the flick of a switch, normal "Autoin. operation may be overridden turning your connected device "Offin. from operation or always "On.in.
The BL932700 features a 4 - 20 mA analog output for connection to a data logger, chart recorder, or other device.
A normally open contact may connect to a level controller or flow monitor. This safety feature may be used to prevent continuous dosing in the event of specific or undesired system conditions.
An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
