Evolution Of Automotive Pressure Sensors

As a Hall Sensor Manufacturer, let us introduce the evolution of automotive pressure sensors.
Almost all gasoline vehicles are composed of an engine control module (ECM) that combines sensors and actuators to form an engine control system. The most critical input control for this system is the manifold absolute pressure (MAP) sensor. In the "speed density" state, the MAP sensor is able to detect the air flowing in the engine to determine the injection time and pre-ignition time for optimal operation. Even vehicles that rely on direct measurement of intake air volume need to be equipped with atmospheric absolute pressure (BAP) sensors, mainly for high-pressure measurement compensation. Today, manufacturers produce tens of millions of MAP and BAP sensors every year, and have driven several generations of pressure sensor modules over the past decade.
Today, the main design of MAP and BAP sensors is a piezoresistive pressure sensor derived from silicon micromachining. Most of them are used in passenger cars, laying the foundation for the application of micromechanical pressure sensor technology in other emerging automotive industries, such as pressure measurement in exhaust gas recirculation systems (EGR), evaporative emissions in fuel systems, and Pressure measurement of fuel injection systems, etc.

Omnipolar Hall IC

图片
  Omnipolar Hall IC The omnipolar Hall-effect sensor  includes the following on a single silicon chip: reverse voltage protector, voltage regulator, temperature compensation circuit, Hall-voltage generator, signal amplifier, Schmitt trigger and open-drain output driver, etc. Produced with CMOS technology, an omnipolar Hall IC is asked for lower supply voltage and less power supply. It is available in two package types: SOT-23-3L (Type M) and TO-92UA (Type UA). More detail of China Hall Sensor , please via: https://www.ahest.net/

Method Of Detecting Switch Type Hall Sensor

图片
In the use of hall sensor for maintenance machinery, we will encounter holzer not working, from holzer's shape can not distinguish whether the holzer element is damaged, and how to detect whether the switch type of hall sensor is damaged. Taking Holzer YS282 as an example, the test method of switch type Holzer element is as follows: First, find a resistance R of 1K Omega, which is connected to the figure 1 and 3 feet, and connect the positive pole of the DC power of the 12V to the foot of the  switch type hall sensor YS282, and the anode is connected to the foot. The multimeter is placed in a DC 50V file, the red pen is connected to the foot, and the black pen is connected to the foot, and the pointer changes of the multimeter are observed. When the magnet N is very close to the test point of the hall sensor YS282, the pointer of the multimeter is deflected from the high level to the low level; when the N pole of the magnet is far away from the test point of the Holzer element Y

How To Use Water Flow Sensor？

图片
The  Water Flow Sensor  consists of a plastic valve body, a water rotor and a Hall Effect Sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This type of sensor can be found on different diameters, water pressure (MPa) and flow rate (L/m) ranges. Make sure to select one that will cover your needs. The sensor that I have it has 20mm diameter, <1.75Mpa water pressure and ~30 L/m flow rate range. A  Water Flow Meter Sensor  is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.  Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall cost-of-ownership. The question is: What water flow meter should you choose for your w
