Parker offers Level Control Sensors for both oil and liquid applications. They are both stand-alone sensors with control funtion built in for safe and easy distribution of oil and refrigerants. The HBLC, Liquid Level Control, is designed to work in conjunction with a 4-20mA modulating control or solenoid valve, and the HBOC, Oil Level Control, is made to work with a 24V DC solenoid valve. These compact and cost effective sensors provide accurate detection of oil and refrigerant levels in equipment.
