SPD...G Gauge Pressure Sensor Product description
The Smart Pressure Device SPD series of pressure sensors are silicon based and encapsulated in modified plastic Dual In Line packages, to accommodate six pins for through-board printed circuit mounting.
The sensors come in two distinct types: Gauge and absolute. The gauge type merely measures the pressure with respect to the atmospheric pressure. The absolute type contains a reference vacuum chamber, which is formed on the die during manufacturing.
The output voltages of both types are proportional to the pressure that is measured.
Various pressure ranges are available. On request, other ranges and encapsulations can be supplied. Please contact our sales department for more information.
Because of its bridge resistance value, the SPD pressure sensor is especially suited for use in combination with the Universal Transducer Interface (UTI03), which gives an easy and very accurate interface to a digital environment.
