The ASL low cost miniature pressure transmitter, has a piezoresistive ceramic pressure sensor which is chemically inert and has very fast dynamic response. The housing is made from stainless steel with a choice of Internal O ring seals to select to ensure the product is suitable for a the applications mentioned below. Every device is temperature compensated, calibrated, supplied with a traceable serial number and calibration certificate. The electronics incorporates a microprocessor based amplifier, this means there are no adjusting pots and therefore the electronics is very stable, especially in high vibration/shock applications.
