Senect ORP Controller

Q: Is the ORP probe included?

Yes — unlike the wider SENECT range, this controller ships with the ORP sensor and the actuator cable, so there is no separate probe to order.

Q: What ORP range and accuracy does it read?

-1,000 mV to +1,000 mV at ±2.5% accuracy, on a 6 m cable as standard. Senect does not publish a resolution figure for this sensor.

Q: How does it control the ozone generator?

It sends a 4-20 mA signal to the generator and modulates injection to hold your set ORP level, for example 300 mV.

Q: Will it work with my ozone generator?

It will if the generator accepts a 4-20 mA control input. It is commonly paired with ClearWater Tech generators and we can wire the complete package before shipping.

Q: What are the spare relays for?

Two of the three relays are free once ozone control is assigned, so you can also switch a feeder, lighting, a pump or an alarm from the same unit.

Q: What if I need to control more than ORP?

Step up to the wider SENECT range, which offers up to 6 sensor inputs and 6 relays and covers dissolved oxygen, pH and conductivity as well.

Q: Can I change the set point remotely?

Yes — over WiFi through the free SENECT Control App on a phone, tablet or PC, which also pushes alarm messages.

A controller that holds a set ORP level by adjusting the ozone generator, for ozone dosing in RAS and water treatment.

Product Information

Key Features

Closed-loop ozone control — the unit holds a set ORP level (300 mV, for example) instead of dosing blind, which removes the overdose risk
ORP sensor and actuator cable are supplied with the controller, so it works out of the box; no probe to order separately
Sensor measures -1,000 mV to +1,000 mV with ±2.5% accuracy, on a 6 m cable as standard with extensions available
Replaceable electrode with a BNC connector in a silicone-housed transducer, so a worn probe is a cheap consumable rather than a new controller
Drives the ozone generator over a 4-20 mA signal, with 3 output relays in total — one for ozone, two spare for a feeder, lights or a pump
Built-in WiFi (WLAN) and the free SENECT Control App for remote monitoring, set point changes and push alarms from phone, tablet or PC
Scalable — several Senect units combine into a single software system, and we can wire a complete ozone package before shipping for plug-and-play start-up
This is a single-parameter, single-loop controller with one sensor input, so there is no model to size: check your ORP set point sits inside the -1,000 to +1,000 mV range, that your ozone generator accepts a 4-20 mA input, and that two spare relays are enough for anything else you want switched. If you need more parameters or more relays, move up to the wider SENECT range.
