Oil Leak Detector Apolarm™C(CSR-3005)
Standerd model (CSR-3005)
The Apolarm™C oil leak detector is designed for use at tank yards and other facilities where large amounts of oil are stored, to quickly detect leaks and prevent leaked oil from entering effluent water flows.The Apolarm™C is the leading oil leak detector, with some 30,000 units sold throughout the world.
The CSR-3005 is the culmination of over three decades of improvements and modifications based on practical experience in a wide range of commercial settings.
Oil Leak Detector MicroApolarm™(CSR-1505)
The MicroApolarm™oil leak detector is designed for optimum performance in small indoor or underground drain pits for conduits or channels.
It comprises a floating-body hermetically-sealed capacitance sensor (CSR-1505) and a signal converter(AS-20)for power supply, signal conversion, and alarm activation. The CSR-1505 sensor circuit applies a high-frequency potential to three electrodes which project downward from the float body.
If an oil layer forms on the water, and the electrodes thus project into oil rather than water, it effectively lowers the capacitance between the electrodes and ground. This change is detected, amplified, and conveyed as a signal current from the sensor circuit via the sensor cable to the AS-20 signal converter, which then engages the oil leak alarm circuit.

System schematic
Apolarm™C (CSR-3005)
| (1)TC-SE Low-water guard | For applications where water level may become too low for the detector unit to float. The adapter grounds the electrodes to prevent false alarms when water is low. |
|---|---|
| (2)4A-8 Cable float | Installation of cable float recommended to prevent cable tension or entanglement due to rough water surface. |
| (3)CSR-3005 sensor | |
| (4)Guide bar | For application in a wide space, with high flow, or with rough water surface. Guide bar prevent the sensor from drifting and tilting. |
| (5)Guide bar supports | Install as appropriate when guide bars are used. |
| (6)Junction box | Required for attachment of extension cable when the sensor and signal converter are installed more than 12 m apart. |
| (7)Extension cable | Install as necessary when the signal converter is more than 12 m from the sensor. |
