The PS-220 Analog Leakwise Controller is a power supply and signal processor that interfaces with a single (1) Leakwise ID-220 Series Sensor to report hydrocarbons spill/leak alerts, including layer buildup and thickness, to users via outputs interfaces for local or remote reporting. The PS-220 has a well proven reliability and is cost effective for a basic monitoring system. It can be AC or DC line powered.
Typical PS-220 and Leakwise ID-220 Series Sensor applications include oil spill/leak monitoring in tank farm sumps, discharge from wastewater treatment plants, hydrocarbon pipeline pumping stations, hydroelectric and fossil fuel power plants, transformer substations, groundwater monitoring wells, remediation sites, etc.
• Low-power consumption.
• Built-in self-diagnostics of the controller and Leakwise Sensor.
• Simple calibration procedure.

The PS-220 supplies stabilized 12 VDC for powering the sensor. The returned current signal from the sensor is filtered and amplified, and then it is compared to two (2) alarm set-points to determine the status that the sensor reports: Water, Oil, High-Oil or Air, depending on the application. There are two relay outputs with dry contacts for reporting the status. An additional fail-safe operated relay reports sensor or power failure. There is an option to turn on a low-pass filter for applications with turbulent water and avoid false alarms. An optional 4-20 mA output reports oil layer thickness. An optional Bar-Graph visualize the oil layer thickness.
