Description
The oil pressure sensor is installed on the main oil passage of the
engine. When the engine is running, the pressure measuring device
detects the pressure of the oil, converts the pressure signal into
an electrical signal and sends it to the signal processing circuit.
After voltage amplifiion and current amplifiion, the amplified
signal is amplified by the signal line. The pressure signal is
connected to the oil pressure indior, and the ratio of the currents
passing through the 2 coils inside the oil pressure indior is
changed to indie the engine oil pressure. The pressure signal after
voltage amplifiion and current amplifiion is also compared with the
alarm voltage set in the alarm circuit. When the voltage is lower
than the alarm voltage, the alarm circuit outputs an alarm signal
and lights the alarm light through the alarm line.
The wiring method of the electronic oil pressure sensor is exactly
the same as that of the traditional mechanical sensor. It can
replace the mechanical pressure sensor and directly connect with
the automobile oil pressure indior and the low pressure warning
light to indie the oil pressure of the diesel engine engine and
provide a low pressure warning signal. Compared with the
traditional piezoresistive oil pressure sensor, the electronic
automobile oil pressure sensor has the advantages of no mechanical
moving parts (ie no contact), high precision, high reliability,
long life, etc., and meets the requirements of the development of
automobile electronics. .
Due to the harsh working environment of the automobile, the
requirements for the sensor are very strict. In the design of the
electronic automobile oil pressure sensor, it is not only necessary
to select a pressure measuring device with high temperature
resistance, corrosion resistance and high precision, but also a
reliable performance and wide operating temperature range.
components, but also need to take anti-interference measures in the
circuit to improve the reliability of the sensor.
