Product description

Air conditioning pressure transmitter circuit electricity low how to return a responsibility? 1, the operation of air conditioning depends on whether the clutch is closed. The general conditions of inspirations are as follows: the high and low pressure switch is normal, the idle speed is normal, the engine is under no special conditions, the air conditioner switch is on, and the circulating air switch is on. High voltage switch: This is a protection switch, the voltage may be inversely proportional or proportional, so your fault is likely to be reported this switch or low voltage switch. The switching state is :(1) insufficient heat dissipation, high pressure on the high pressure side; (2) excessive refrigerant charging, high pressure on the high pressure side; (1) To find the reason, we can focus on whether the condenser is blocked and whether the cooling fan is running. (2) The reason can be respectively connected to the high pressure side and low pressure side of a group of pressure gauges, whether qualified. (3) The high voltage switch itself is faulty, replace. Low-voltage switch: This switch is generally disconnected only when the refrigerant is charged too much or too little, and only needs to be charged according to the standard volume. Of course, it could be the switch itself. Specializing in the manufacture of intake manifold absolute pressure sensor, high precision pressure sensor, water pressure sensor, refrigerant pressure transmitter, air conditioning pressure transmitter, etc.
