General Description

Model OX optical interface sensor consists of a sensing probe and a separate electronic converter. Sediments, suspended solids, and interface of immiscible liquids are detected by using an infrared transmission operating principle. By transmitting the infrared light with pulse modulation, a strong beam goes through build up and fouling on the probe surfaces. Ambient light is electrically disregarded by using a special frequency.

The sensing probe is submersible and the PVC housing, PP sealing connector, and FEP covered probes are compatible with a wide range of liquids. Special PVC cable lengths are 20 meters. The detecting level can be easily adjusted by altering the height of the cable fixing point.

The electronic converter has a switch selectable High or Low fail-safe mode for relay safety. An adjustable 0.5 to 1 0 seconds switching delay is provided in order to avoid transient on/off signals.

Operational Description

When AC power is applied to a pair of isolated electrodes, without liquid between them, no current is delivered. When there is liquid, it becomes a part of electrical circuit and a current is delivered. When liquid contacts the electrode, MT directly detects the resistance and compares it with the value set in the relay unit to determine the liquid presence, then sends signals to amplifier, causing the relay to give output signals.

Operational Description

The OX consists of two element probes. A beam transmits from one which has a built in infrared emitting diode to the other which has a built in photo detector. When the probes are immersed into medium, the infrared beam transmission is decreased. This damping is detected and converted into an electric relay output.
