PD-10 PAA-10 PA-10
The KELLER Series 10 sensor is mounted with the compensation resistors in a stainless steel housing. The sensor floats on an O-ring seal and is therefore free of any housing stresses. It is particularly suited in connection with PAP-based signal processing. Transducers can be ordered with the coefficients of a mathematical model ready for integration with a PAP-base
system. Error Bands of 0,1%°≠0,01 %FS are achievable, depending on the temperature ranges Whilst the Series 11 fulfils all the classical functions expected of a mV-transducer, it is often used in development of larger OEM projects to test the performance of the KELLER OEM sensors. As a special order, any OEM sensor from Series 3 to 10 can be ordered in such a housing, with or without integrated compensation resistors. The customer can then verify that the chosen OEM sensor is suitable for the application.

The Series 41 X combines the ceramic measurement cell for low pressure ranges with the µP electronics of the digital Series 30 transmitter. The pressure values from the signals of the pressure and temperature sensors are determined by polynomial compensation (see reverse). The values can be displayed and stored on a PC via an RS485 interface and programming can also be carried out. The transmitters are calibrated to the base range. The PROG30 software permits programming of the analog output signal in each section of the range within the base range (e.g. range 100 mbar. Output 4…20 mA for 20…60 mbar). With KELLER RS converters K-100 Series, up to 128 transmitters can be hooked together into a bus system and read by means of a PC or laptop. READ30 software allows the current pressure of each transmitter to be read or the pressure activity of several transmitters to be recorded or stored whilst “on line”.

The KELLER Series 21 / 21 PRO are extremely reliable and cost effective pressure transmitters. These pressure transmitters use a programmable KELLER-ASIC microchip called!±ProgRes!±  (programmable resistors).
The modular design of the Series 21 C and the extensive vertical range of in-house manufacture provide a high degree of lexibility. The company can quickly adapt to customer requests, even with large production batches. The extensive standard range of connectors and pressure connections means that a CIO measuring cell (Chip-in-Oil) can be quickly welded in from stock if small numbers are involved, and then calibrated to the required temperature range. RoHS conformity and comprehensive EMC protection are a matter of course, therefore qualifying the Series 21 C for use in industrial areas.

Series 21G, is the result of a 20 year long development programme for industrial transmitters. ‘G’ stands for ‘Graduate’; this product has received ‘summa cum laude’.... the highest honours. The standard mPm electrical connector overlaps the body to remind us of ‘mortar board hats’ on graduation day.
These piezoresistive silicon pressure transmitters are produced on the new KELLER automatic brazing lines, making possible the mass production of high quality pressure transmitters at low cost.This new technology allows the crevice-free construction of the pressure port without using seals or O-rings. In the brass sensor line (Series 21 MC), a steel insert and a nickel
diaphragm is brazed into a brass housing. In the steel sensor line (Series 21 SC), all parts are of stainless steel (AISI 316 L). The header with the silicon pressure sensor and glass lead through pins is welded to the steel insert underneath the oil filling. The tiny chip-on-board amplifier (weight  1 gram) with the KELLER-specific !°PROGRES!± circuit is mounted direct
on the glass feed-through pins. It is then encapsulated in silicone compound for humidity and vibration protection.
Note: The cable version of the transmitters has exceptionally high RFI protection.

Series 22 DT was developed and homologated specially for use in so-called °∞bivalent vehicles fitted with engines for combined natural gas/gasoline operation. The unconventional design with a small mass swept by the flow results in a fast response with temperature changes, the temperature being measured by an NTC or PT sensor located directly behind
the stainless steel separating diaphragm. The same diaphragm transmits pressure via a capillary to a stress-free mounted silicon measuring cell. The signal processing for pressure and temperature is carried out by an electronic module connected to the sensors by flexible conductors. Mounted to the back of the electronic module, which is directly connected to the 6-pole plug connector are the EMC protection components. A special feature is the immunity from interference from electromagnetic fields up to 200 V/m.SPECIFICATIONS

The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1,5 Kelvin (K) wide. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analogue signal path depending on the temperature. Each temperature is the „calibration temperature” for this transmitter. The accuracy thereof is mainly determined by linearity. 120 fields are available, representing a possible temperature range of 180 K. The wider the temperature range, the greater the amount of testing that is needed to minimise the inaccuracy of the mathematical model. The Series 23 (S)Y/25 Y product line is outstanding due to its extreme ruggedness towards electromagnetic fields.

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.
