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. Application Oil or Ammonia, Halocarbon & Brine Cable Length Optional 10' Cable Maximum Operating Pressure (barg) 150 Maximum Operating Pressure (psig) 2175 Connection Thread Size (inch) 3/4" NPT Minimum Ambient Temperature (C) -20 Minimum Ambient Temperature (F) -4 Maximum Ambient Temperature (C) 50 [...]
CO2 Switch HBSC2 is a level switch for detecting liquid CO2 in refrigeration systems. Typically, it is installed in/on the receiver, but it is also suited for installation in other locations where a level indication is needed. The sensor's measurement principle makes it unique for these purposes, since the properties of the measurement principle as well as its special construction allows it to withstand high pressure and low refrigerant temperatures. The sensor is suited for use on transcritical CO2 refrigeration systems. Markets: • Industrial Refrigeration • Commercial Refrigeration Features and Benefits: • Complete solution with sensor and transmitter in one unit. • Simple to install by one thread sleeve. A cost optimized solution • LED indication of power supply and alarm status • Unique split [...]
HBDX is a new revolutionary, patent-pending sensor technology, and it is thus the first sensor in the world capable of measuring the relationship between vapor and liquid a refrigeration system. The sensor measures the degree of dryness, “X”, of the gas in the gas pipes, and the value is converted into a 4-20 mA analogue signal corresponding to “X”. The HBDX measures the dryness of the gas in the range X = 0.85...1.05. The sensor is available in two variants, "Rod Style” for installation in a pipe elbow and “In-line” for welding into the suction pipe. The sensor offers very precise measurements and provides instant read-outs of the gas quality, making it useable in most evaporators (plate, pipe, and air evaporators). The sensor’s microprocessor also [...]
The HBLT-WIRE is a field adjustable capacitive liquid level sensor designed to measure refrigerant levels in traditional stationary systems such as vessels, receivers or accumulators, as well as in marine systems. Better, compact and cost efficient, the HBLT-Wire is a field adjustable capacitive liquid level sensor designed to measure refrigerant levels in traditional stationary systems such as vessels, receivers or accumulators, as well as in marine systems. The HBLT-Wire is an all-in-one length probe. The flexible sensor wire provides on the job length adjustability, so one part number covers all application requirements. The sensor has an output signal of 4-20 mA, which is proportional to the 0 and 100% of liquid level. Markets: • Industrial Refrigeration • Commercial Refrigeration [...]
The LLSS refrigerant float switch provides an electrical switching action in response to change in the refrigerant levels in various applications where control and monitoring of liquid levels are required. Parker’s LLSS Refrigerant Float Switch offers proven and reliable operation by using a mechanical switch and magnet mechanism. This reliability will reduce complexity, reduce replacement costs and offer enhanced system safety. The LLSS uses corrosion resistant components including a stainless-steel float chamber to ensure a long lifetime in the harsh environments of industrial refrigeration. The Float Switch is used to open and close solenoid valves, to activate or de-activate electrical controls, to energize or de-energize magnetic starters for starting and stopping refrigerant liquid pumps and compressors, and as a safety device, to sound [...]
