    This piezoresistive pressure transmitter fits 19 mm ( 3/ 4”) manifold pressure ports for applications in bio- reactors or autoclaves. The transmitter is compensated up to 150 °C and may be operated continuously or sterilised at this level, including the special circuit electronics. The transmitter circuit is based on the “PROGRES” programmable KELLER amplifier.

    This piezoresistive high temperature transmitter ( - transducer) is suited for media temperatures up to 300! aC. The pressure, acting onto the flush diaphragm, is transferred over an oil- fille capillary onto the silicon measuring cell. The capillary has the function of a cooling spiral. When measuring media with temperatures of 300! aC, the temperature at the silicon cell onl

    increases by 100! aC. The integrated amplifier electronics provide a voltage- or current signa proportional to the pressure.

    For highly aggressive media, KELLER offers pressure ports in different materials.

    In applications where the differential pressure is more than 5% of the maximum standard pressure range, differential pressure measurement with two absolute pressure sensors offers major advantages over conventional methods of differential pressure measurement ( such as the Series PD- 10) . The Series PD- 39 X does not measure the differential pressure directly - instead, it uses two absolute pressure sensors to take the measurement indirectly. As well as reducing costs, this differential pressure transmitter is also more robust in relation to unbalanced ( one- sided) overloading. The differential pressure range should be at least 5% of the standard pressure range.

    The Econoline by Keller America is a general purpose pressure transmitter intended for almost any application involving aggressive media and where small size, weight, and low cost are required. This proven design utilizes a media isolated, piezoresistive silicon sensor, a design known to be highly reliable in thousands of applications around the globe. Combined with state- of- the- art signal conditioning electronics, the result is a robust transmitter that will provide trouble free service and

    accurate results. For more information on the Econoline, or any other Keller product, please con- tact Keller America, or view the entire.

    The Preciseline by Keller America pro- vides standard features that far exceed those of comparably priced transmit-

    ters by combining proven piezoresistive silicon sensor technology with Keller! ˉs state- of- the- art signal conditioning cir-

    cuitry. The result is outstanding ! Ã 0.25% FS standard ( ! Ã 0.1% optional) Total Error Band ( TEB) accuracy over a wide com-

    pensated temperature range. The ability of the Preciseline to provide this level of sustained performance over a wide range of operating condi- tions makes it ideally suited to pressure monitoring applications such as tank level measurement, pump control, and VFD control. Plus, guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning.

    Series 23 ( S) Ei, 25 ( S) Ei and 26 Ei pressure transmitters are all ATEX approved for use in Hazardous Areas where there is a high risk of explosion. Series 23 Ei / 26 Ei The Series 23 Ei / 26 Ei achieve high stability ( especially in low pressure ranges) with large piezoresistive capsules and stress- free, floating mountings with O- rings. Series 23 S Ei / 25 Ei / 25 S Ei

    The 23 S Ei / 25 Ei / 25 S Ei offer a complete range of „Ported“ and „Flush Diaphragm“ pressure transmitters for ranges of 1bar and above. Still giving high stability and accuracy but without any internal O- rings. This is achieved using either an all welded 316L stainless steel housing and diaphragm or an all welded 316L housing fitted with a brazed Nickel diaphragm.

    – A complete range Absolute, barometric, gauge ( positive and negative) . 16 nominal pressure ranges. Current or voltage output.

    – Flexibility A modular concept is used, with fast and economical production achieved by using off- theshelf sensors.

    69. Murphy pressure transmitter Direct Mount Pressure Switch Model PSB PD8100 Series, PXT- K Series

    The PSB switch is a direct mount switch for critical pressure points. It has one limit contact that can be used to activate an alarm, actuate indicator lights or shutdown equipment.

    The construction of this instrument is the same as our time- proven Swichgage® instrument. A precision machined brass mounting plate and port captures a high quality stamped beryllium copper diaphragm. The single- pole, double- throw ( SPDT) snap- switch is operated directly from the diaphragm for quick acting and positive switching. Trip point is factory preset according to your specifications.

    Housing is weather sealed to prevent entry of moisture, dust, etc. A glass- filled nylon terminal block with quick screw terminal connections gives the PSB switch a real advantage in industrial engine applications. The PSB is ideal when reading is not desired, but pressure is critical to operational efficiency.

    Intended for use in general purpose nonclassified areas.

    • High Stablity

    The PXT- K Series pressure transmitters are state- of- the- art instruments providing 4- 20 mA output. Each Piezoresistive Pressure Transmitter contains a transducer comprised of a piezoresistive silicon chip mounted on a glass- metal feedthrough header welded into a stainless steel housing and filled with silicone oil; the very thin laser- welded stainless steel isolation- diaphragm completes the front side.
