These compact Single Point Level Sensors and Switches are economical solutions for reliable and accurate level detection. They are designed to detect the presence of ammonia or halocarbon refrigerant liquid (but not oil) at a specific location in vessels containing refrigerant by capacitance-type, non-optic sensing.
Hansen SEE-LEVEL™ Refrigerant Liquid Indicators provide simple indication of true liquid levels in industrial and commercial refrigeration systems.
The Hansen Vari-Level Adjustable Level Control provides excellent level control and monitoring flexibility for industrial and large commercial refrigeration systems. It takes the place of multiple single point level switches on new or existing refrigerant vessels.
These specially-designed Techni-Level Transducer Probes with 4-20 mA output are for refrigerant level control in computer operated industrial and commercial plants.
Designed to be inserted directly into refrigerant receivers and facilitate the continuous measurement of refrigerant liquid levels.
The HT100, HT200, and HT300 High Side Floats (Float Drain Regulators) are typically used to drain condensers to chillers, recirculators, controlled pressure receivers, or flooded evaporators; to drain hot gas supply mains; or to drain liquid condensate from heat reclaim coils.
The HD101 Defrost Drainer, a variation of the HT100 high side float, has an adjustable vent valve bypass to fine-tune individual systems which may experience evaporator defrost gas binding.
The Hansen Refrigerant Float Switch (HLL series) is used to electrically indicate or control a liquid level by opening or closing a single pole, double throw (SPDT) switch. Its simple, reliable design provides long life performance for almost any application.
