Mass airflow sensors

A growing focus on reducing CO2 emissions means that mass airflow sensors are becoming increasingly important in ensuring the optimum air fuel ratio.



Mass airflow sensors are positioned directly after the air filter in the intake manifold and supply information on temperature, humidity and intake air volume. Despite their highly compact construction they feature precision technology to capture information, which – together with other engine data – enables optimum engine management.

This data includes:

Intake air temperature
Intake air humidity
Intake air volume
In gasoline engines, mass airflow measurement is used in conjunction with other sensor readings to regulate the supply of fuel to the engine.

In diesel engines, mass airflow sensors are used to regulate the exhaust gas recirculation rate and calculate the maximum injection quantity.

Our mass airflow sensors are exceptionally reliable and highly capable of withstanding environmental factors. Their dynamic measurement ability makes an important contribution to reducing vehicle emissions.

multimeter

What is a digital multimeter? A  digital multimeter  is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries. Digital multimeters long ago replaced needle-based analog meters due to their ability to measure with greater accuracy, reliability and increased impedance. Fluke introduced its first digital multimeter in 1977. To better  understand  digital  multimeters,  it’s  helpful  to  become  clear  on  the  basics  of electricity.                       After  all,  digital multimeter  always  measure  some  aspect  of  electricity. In  the  case  of electricity,  that  force  might  be  a...

Zoomlion Qy 50v Load chart free pdf download

A Chinese construction machinery manufacturer, having taken on the mission of contributing to our motherland through industry and through the great ambition of "broadening our vision by aiming high" for more than fifty years, we have taken one firm step after another on our way towards allowing "Made in China" to challenge the world standard. With steps restlessly marching forward and with a long, winding path covered by single individual strides for over half a century, each and every footprint made, burdened under heavy loads, demonstrates nothing but the strong demeanor and ambition that a climber shows while looking down upon everything from mountain peak. We have experienced innumerable glorious moments over the past fifty years, such as: showing our strength in the centennial Three Gorges Project, being highly praised for building the Antarctic Scientific Exploration Bases, challenging the extreme construction conditions on the Qinghai-Tibet Platea...

Ammeter

It's Electronic device in which we measure current in amperes (A)in close Circuit. It is connected in series with circuit. The effective resistance of ammeter is low The Resistance of an ammeter is zero. A moving coil of galvanometer is converted in to an ammeter by connected a suitable low resistance in parallel to it. Circuit must be disconnected in order to attach the ammeter. Ammeter considered as less accurate value. Type of ammeter There are 7 type of ammeter. 1.Moving coil  2-Moving magnet  3-Electrodynamic  4-Moving iron  5-Hot wire  6-Digital  7-Integrating Moving coil ammeter:                                   The D'Arsonval galvanometer is a moving coil ammeter. It uses magnetic deflection, where current passing through a coil causes the coil to move in a magnetic field. The modern form of this instrument was devel...
