Standerd model (CSH-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 CSH-3005 is the culmination of 40 years decades of improvements and modifications based on practical experience in a wide range of commercial settings.

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 (CSH-1505) and a signal converter(ASH-40)for power supply, signal conversion, and alarm activation. The CSH-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 ASH-40 signal converter, which then engages the oil leak alarm circuit.
Salient features
Oil-resistant, chemical-resistant, weather-resistant float Operation unimpaired by rough water surface No false alarms due to dirt and slime on electrodes
No special maintenance required ? only periodic cleaning of float surface Alarms indicate signaling unit malfunction, cable disconnection, and cable short
Able to detect high-viscosity oils Optional 50 mm electrodes enable thickness of detectable oil layer to be increased
Sure, accurate oil detection by sensor just 150 mm in diameter. Efficiency and ease of use in indoor and underground channel drain pits.
System alarm automatically initiated by relay circuit, in the event of power loss at signal converter, cable disconnection, or cable short-circuit.
