SENSORES DE PRESION

How Pressure is measured

Pressure sensors work on a differential basis by measuring the difference between the applied pressure and a reference pressure. The reference can either be absolute vacuum pressure or atmospheric (ambient air) pressure. The sensor is therefore said to measure either ‘absolute’ or ‘gauge’ pressure.

Atmospheric pressure varies constantly from place to place, moment to moment depending on ambient weather conditions. The standard atmospheric pressure is approximately equal to typical air pressure at sea level and standardised to 101.325 kPa [or 0 psi(sg), 14.7 psi(a), 1.01 bar].

Absolute Pressure

An absolute pressure sensor measures pressure relative to absolute vacuum.
A sensor held out in normal air at sea level will show around 101 kPa [14.7 psi(a), 1.01 bar].

For example, manifold pressure (MAP) sensors are absolute pressure sensors, as these sensors are required to measure pressures both below (vacuum) and above atmospheric pressure.

Gauge Pressure

Pressure can be measured relative to atmospheric pressure. This is known as gauge pressure and in technical work, should be written as psi(g).

For example the air pressure in a tire of a car, which might be said to be ’30 psi’, is actually 30 psi above atmospheric pressure and should be more accurately referred to as 30 psi(g).

Sealed Gauge

Sometimes the rear of a sensor is sealed to prevent contamination and improve the repeatability of readings.

The zero point of the sensor is set to standard atmospheric pressure. This may not be exactly the same pressure as where you are on any given day, resulting in offset readings. Changes in temperature and atmospheric pressure will not effect the reading from sealed gauge sensors, it is an accurate measurement of actual gauge pressure above standard atmospheric.

Sealed gauge measurements are labelled as psi(s) or psi(sg).

Pressure Sensors

MoTeC supplies a wide variety of quality pressure sensors, all of which have been tested and calibrated to suit MoTeC systems. These sensors come in a variety of pressure ranges, and can be set up within the Dash Logger or ECU to show many units, including psi(g), psi(a), kPa(g), kPa(a) and bar. Some sensors are available to suit specific applications such as Nitro methane compatible sensors.

MoTeC supplies the following types:

• Air pressure sensors
• Fluid pressure sensors

CRNAK CAM & SENSORES DE VELOCIDAD – HALL

HALL SENSORS

Hall sensors contain a semiconductor Hall effect integrated circuit (IC) and a magnet. There are Hall sensor types available that can be used with a tooth (gear) style trigger wheel for measuring crank angle or wheel speed, and types that use a vaned rotor passing through a Hall sensor gap.
The IC detects changes in the field strength as the vane passes through the sensor gap or a tooth passes the sensor tip. The output voltage changes from low to high (or high to low) when the leading edge of the tooth passes the centre of the sensor.
The vane or tooth material must be magnetically soft, such as mild steel—do not use stainless steel.

CRNAK CAM & SENSORES DE VELOCIDAD – MAGNETICO

MAGNETIC SENSORS

A magnetic sensor consists of a wound coil of wire that generates a voltage between the sensor wires when the magnetic field strength changes as the tooth passes the sensor. The output voltage amplitude depends on the gap between sensor and tooth and increases with increased speed past the trigger wheel.

Magnetic sensors may be used if the trigger wheel has a large number of teeth as the sensor has a small magnetic pole size. They are often used as crankshaft or wheel speed sensors.

The sensor may be wired for either a rising or falling waveform by reversing the wires. The ECU should be setup accordingly. The tooth material must be magnetically soft, such as mild steel (do not use stainless steel).

Magnetic sensors must use shielded wire to help eliminate unwanted electrical noise and must be mounted rigidly as any vibration can cause false signals.

MAGNETIC SENSOR AMPLIFIERS

The Dual Magnetic Converter (DMC) converts magnetic style signals to open collector output signals – a square wave. This makes a typical magnetic sensor behave as a switched or Hall Effect sensor, to make the signals suitable for use with MoTeC ECUs and loggers.

This allows magnetic sensors to be used in applications where previously a Hall sensor was required, for example when using the digital inputs on an ECU to measure wheel speed.

A single DMC can convert two independent magnetic sensor signals.

The DMC comes in 4 versions, each having different trigger levels according to the requirements of the intended application.

• DMC A
  This version is intended for fuel flow sensors which have a very low trigger level.
  Heavy filtering minimises the possibility of interference, resulting in significant variation of the trigger level with frequency.
• DMC B
  This version is intended for engine trigger sensors that have insufficient amplitude to trigger a logic level input.
  Minimal filtering avoids delays in the signal. The trigger level does not vary significantly at normal operating frequencies.
• DMC C
  This version is intended for ignition system input conditioners, typically used in drag racing, for measuring ignition timing.
• DMC D
  This version is intended for magnetic wheel speed sensors.
  The signal should be symmetrical around zero volts.
  Heavy filtering minimises the possibility of interference, resulting in significant variation of the trigger level with frequency.
