TECHNOLOGY:

The new series of KELLER pressure transducers Y series offers users an extremely small thermal error and resistance to electromagnetic influences, exceeding the latest applicable standards.

The special newly-developed compensation technology used in the Y series pressure transducers allows for a significant reduction of thermal errors of the pressure sensor. The effect of temperature on the accuracy of pressure measurement with a piezo-resistive sensor is much larger than the error in the sensor's non-linearity, which is not always reported by other manufacturers! The quasi digital technology of the Y series transducers divides the temperature field into small 1.5K clusters. Zero and gain compensation is made for each of the small 1.5K fields in accordance with the programmed mathematical model. Any temperature can therefore be considered a calibration temperature. Thus, accuracy is mainly determined by the non-linearity error (typically 0.2%) and sensor stability.

FLEXIBILITY:

The 21Y Series uses modular production technology which applies standard measuring capsules, produced in very large quantities (about 1 million per year) and programmable Prom Comp electronics allowing enormous production flexibility. The steel capsule is welded into the selected housing. The lack of internal seals ensures trouble-free operation even with aggressive media! The appropriate electronics are later calibrated and programmed using a wide temperature and pressure range at one of 1000 calibration stations at KELLER. We offer a variety of process and electrical connections. The transducers are made for absolute pressure (PAA-), quasi relative (PA-) and relative pressure (PR-). Of course, measuring underpressure (vacuum) is also possible.

OUTPUTS:

Various output signals: current 4 ... 20mA (2 wires) and various voltage e.g. 0 ... 10V, 0 ... 5V, 0.5 ... 4.5V etc (3 wires) are available.

EMC:

Another unique feature of the new series of KELLER transducers is high resistance to electromagnetic field influences. Transducers with multiple reserves (approx. 10 times!) meet new, strict CE standards to be in force since mid-2009. The transducers also have exceptional resistance to potential between the housing and the electrical connection, which is usually important when used near inverters. With high 300V insulation, the product can be used in the harshest conditions.
