» Keller Swiss-built Series 23s-25s High Accuracy Compact Pressure Transmitter
Product Description:
The Series 23S / 25S features a fully welded pressure port construction, no internal O-Rings or seals
are used up to 600 bar. Pressure ranges, pressure ports, signal outputs, electrical connectors, etc.Quality Each transmitter is subjected to severe test- and calibration procedures. Transmitters are manufactured and tested according to ISO 9001:2000.

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.

This high precision of 0, 01 %FS is available as an option (the standard Series 33 X has an accuracy of 0, 05 %FS). These Series are based on the stable, floating piezoresisitive transducer and the newly developed XEMICS micro-processor with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated.

Swiss-Built Series 35X HT-HTT High temperature high accuracy analog digital output pressure transmitter Piezoresistive pressure transmitter 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 transmitters are supplied in absolute or gauge versions, with current or voltage output. The sensing component is a micro-machined silicon pressure chip of high sensitivity. An independent temperature sensor is integrated on the surface of the silicon chip.

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 !à0.25% FS standard (!à0.1% 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. Numerous options and variations are available to meet customers’ specific requirements: Pressure ranges, mechanical- and electrical interface, process- and plug connection, signal outputs etc.
