Programmable microprocessor sensors for stand alone operation from HB Products

The Danish expert for sensors and switches in industrial refrigeration applications is adding its highly reliable microprocessor sensors for ammonia systems. The new HBLC/OC sensors series offers unique stand-alone operation without use of a controller and is designed for direct operation of a motor or solenoid valve.

The newly developed microprocessor controlled sensors from HB Products for ammonia refrigeration systems consists of the HBLC liquid level control sensor and the HBOC oil level control sensor. The HBLC is ideal for liquid level control, use as high/low pressure float, valve control system and defrost liquid drain control. The HBOC on the other hand is ideal for control and management of oil valves, compressor protection with alarm and all kinds of oil return systems.
