Absolute (PSIa) Pressure SensorsAEM
offers high quality stainless steel PSIa sensors in 15 (1BAR), 30
(2BAR), 50 (3.5BAR), and 75 (5BAR). PSIa is referenced to absolute zero.
Absolute zero is the pressure measurement when all the pressure exerted
by the atmosphere has been removed. The most common use for absolute
pressure sensors is reading manifold pressure. PSIa sensors are required
if you wish to measure vacuum. A PSIa sensor will read about 14.7 PSI
when the sensing element is exposed to atmospheric pressure at sea level
however they can be recalibrated to read zero at atmospheric and a
negative number at values less than atmospheric pressure.Which Pressure Sensor is right for you?There
are many different tools that can be used for measurement, but the
degree of accuracy is dependent upon the tool. For example, a ruler can
measure distance with a good degree of accuracy, but for a more precise
measurement a caliper should be used. The difference between a brass
pressure sensor and a stainless steel pressure sensor is similar if we
think about it in these terms:Brass Pressure Sensor = RulerUse a Brass Pressure Sensor where you need a good reference to what pressure is being seen.Example:
Brass Pressure Sensor used for a Boost Gauge _ Reference/Information
for knowing manifold pressure, not for ECU calibration.Stainless Pressure Sensor = CaliperUse a SS Pressure Sensor where you need exact details of the pressure.Example: MAP Sensor information for the ECU _ Calibration/crucial information for the ECU.FeaturesStainless-steel sensors accurate to within 1% of full scale (pressure sensors)High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)Connector and pins includedSpecs30-2130-30 - 30 PSIa or 2 Bar Stainless Sensor KitAccuracy: +/- 1% Full Scale over -40C to 105C includes Repeatability, Hysteresis and LinearityOperating Temp: -40C to 105C / -40F to 221FBurst Pressure: 150PSIResponse Time: < 1msVibration:100 to 2000Hz, 20g Sinusoidal, 3 AxesSensor Body: Stainless SteelWetted Materials: 304L & 316L Stainless SteelThread: 1/8" NPT Male ThreadWeight: < 85 GramsSupply Current:Output: .5 to 4.5Vdc LinearElec.
