Pasta alarm end welding oil pressure sensor, the oil pressure sensor other end welding temperature sensor.
This practicality provide technological merit be：Using two fingers needle and double dial is equipped in not only can be straight on a dial plate
Oil pressure parameter can also be found out by watching out oil temperature parameter, employ LED display for digitlization display, display screen not only shows ginseng
Number, and can also show and alarm because of high oil temperature, the measured value of alarm is originated from the measurement of measuring appliance, when high oil temperature so that oil
Face is risen, when rising certain volume measuring appliance can judge liquid level and transmit electric signal to playing alarm.
As an improvement, the warm jump system knob end is equipped with the graduation mark for adjustment, the temperature jump system knob
There are three gears.
It is external tapping one, external tapping two and external tapping respectively as an improvement, there are three the quantity of the external tapping
Three, external tapping one end electrical connection wind turbine, three end of external tapping is equipped with metal connection, the metal connection
Temperature controller terminal is electrically connected, when high oil temperature generates alarm, at this time air-cooled is unable to effective temperature-reducing, then is dropped using wind turbine
Temperature transmits signal if wind turbine cooling still loses effect and transmits electric signal to interrupting and pre-processing from external tapping, directly
Open circuit.
As an improvement, being equipped with piezoelectrics in the oil pressure sensor, thermistor is equipped in the temperature sensor.
