Keller OEM Sensors, Transducers Series 6 / 6T Piezoresistive oem capsule for sealed gauge and vented gauge pressures

The Series 6 capsules are of all welded stainless steel construction, with integral media isolation diaphragm. No !(R)O!ˉring sea are used. The Series 6 uses a silicon TAB sensor mounted in the oil filled stainless steel capsule, providing a highly stable measuring cell with negligible hysteresis, high output signal and a life of millions of pressure cycles. TAB (Tape Automated Bonding) is a flexible printed circuit system for interconnection between the silicon sensor and the capsule output pins, offering improved reliability and significantly lower production costs. Series 6 is a low cost sensor for OEM use, tested for function only, with no calibration data supplied. Series 6T is supplied tested, with calibration certificate: Linearity, sensitivity, zero point, temperature coefficients 0!-5!aC and compensation resistor values (resistors nt supplied).
