BL-932700-1
The BL-932700 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.
BL-932700 is an ORP mini controller that has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control. As a result of its compact size, BL-932700 can be installed right next to tanks or vats.
An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
- Large Clear LCD
- Fire Retardant Casing
- BNC Connection
Adjustable Dosing Relay
The BL-932700 features a dosing relay which may be configured to dose above or below a user programmable mV setpoint.
Selectable Overdose Protection
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.
Selectable Control Override
With the flick of a switch, normal “Auto” operation may be overridden turning your connected device “Off” from operation or always “On.”
Analogue Output Communication
The BL-932700 features a 4 - 20 mA analogue output for connection to a data logger, chart recorder, or other device.
External Disabling Feature
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.
Matching Pin Connection
An included matching pin option helps protect the sensor from ground loop effects that may lead to erratic readings or system damage.
