The Keller Series 21Y pressure transducer / transmitter is designed for general industrial and OEM applications requiring medium to high measurement accuracy. Its high design flexibility affords numerous options of process and electrical connection. Pressure ranges between 0-2 and 0-1000 bar are available with output signal options of 4-20mA, 0-10V and 0.5-4.5V. The Series 21Y employs active temperature compensation to significantly reduce total error band and has extremely high EMC protection for a transmitter of this class / price point. Total error band including linearity and all thermal errors over 0-50°C is ≤±1%FS max.
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 extent of the vertical range of manufacture, the modular design and the programmable electronics make it possible to manufacture large, customer-specific batches.
The 21 Y product line is outstanding due to its extreme ruggedness towards electromagnetic fields. The limits of the CE standard are undercut by a factor of up to 10 with conducted and radiated fields. These transmitters are also extremely immune to external voltages between the housing and the electrical connection, which is particularly important when frequency converters are being used. The high insulation voltage of 300 V make this product ideal for use in the harshest of environments.
