This Product Selection Guide contains information to help select products in the Pressure Sensors - Industrial category on DigiKey.com
Industrial Pressure Sensors or Transducers are designed to detect and respond to the presence or a change in the amount of force on the device. The pressure types are Absolute, Compound, Differential, Gauge, Sealed Gauge, Switch, Vacuum, and Vented Gauge with operating pressures from -100PSI (-689.48kPa) to 20000PSI (137895.15kPa). These are made for use in an industrial setting.
SelectionCharacteristics
Specifications to determine which industrial pressure sensor is right for your application.
Application: Application is the type of equipment or environment the device will be used in, they are tested and typically rated by a third party to ensure certain minimum standards for the application they are intended for. You could use one with a higher rating, but you cannot use one with a lower rating as it will fail in that application. For example, you could use a medically rated device to replace a commercial device, but you cannot replace the medical device with the commercial device.
Pressure Type: Indicates key sensor attributes, such as zero-pressure reference and applicable use.
Operating Pressure: Characterizes the pressure range or limiting pressure value for which a device is specified to produce valid measurements, or actuation pressures for switch-type devices.
Output Type: Indicates the type of electrical signal the device provides, such as analog, digital, I2C, etc.
Output: The range of the output signal.
Accuracy: Typically listed as +/- and a percentage it represents the deviation from the true pressure that the output of the device may be.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Port Size: Describes the size and connection style of the orifices that carry the working fluid measured by a sensor.
Port Style: Describes the physical form of the pressurized media connector on the sensor.
Features: These are different capabilities or properties of the device such as amplified output or temperature compensation, etc.
Termination Style: Selection of termination style used to connect the device to a system, such as PC pins, wire leads, cable, etc.
Maximum Pressure: The pressure beyond which damage is expected to occur to the sensor; absolute maximum pressure or burst pressure.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Package/Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
