Product description

CNG/LPG high voltage sensor is a kind of detection device, it can sense the measured information, and the measured information according to certain rules into electrical signals or other required information output form, so as to meet the requirements of information transmission, processing, storage, display, record and control. Physical sensors apply physical effects, such as piezoelectric effect, magnetostriction phenomenon, ionization, thermoelectric, photoelectric, magnetoelectric, etc. Small changes in the measured signal are converted into electrical signals. Chemical sensors include sensors that utilize chemisorption, electrochemical reactions, and other phenomena as causal sensors. Small changes in the semaphore under measurement can be converted into electrical signals. A 15V power supply is provided to the sensor, and a crystal oscillator in the circuit is excited to generate a 400Hz square wave. Ac excitation power is generated through the tda2030 power amplifier and transmitted from the stationary primary coil to the rotating secondary coil through the energy ring transformer T1. The resulting AC power supply generates 5v DC power through a rectifier and filter circuit on the shaft. As the operational amplifier AD822 working power supply; The high precision voltage regulator power supply consists of reference power supply AD589 and dual operation amplifier AD822, generating 4.5V DC power supply, as the power amplifier and V/F converter bridge power supply and working power supply. Specializing in the manufacture of CNG/LPG pressure sensor, water purifier pressure transmitter, urea pressure sensor, refrigerant pressure sensor, air conditioning pressure transmitter, etc.
