Keller OEM Sensors, Transducers Series 1TAB OEM pressure sensor

The TAB 1 pressure measuring cells are designed to measure absolute pressures. They are
offered in two different version: Version 1 to be soldered on a glass feed through and welded
in an oil filled housing as for industrial transmitters. Version 2 can be soldered directly on
printed circuit boards of instruments as for the measurement of depths or altitude, where the
surrounding pressure is measured. 
TAB (Tape Automated Bonding) is a special process for contacting the diffused resistors on
the chip. The resistor aluminum contacts are provided with 0,1 mm thick gold bumps. The
pretinned ends of the copper strips on the flexible circuit material are soldered to the these
goldbumps. Each contact is able to withstand a force of more than 1 Newton. TAB bonded
cells withstand extreme conditions in shock or vibration. TAB bonded cells may be surrounded
by high viscosity gels or mouldings in water depth instruments without danger of contact
braking as with wire bonded cell.
