Keller AG has implemented a new concept for temperature compensation and protection from electromagnetic fields (EMC) in their Series 21 Y pressure transmitters.
With measuring ranges between 2 bar and 1000 bar, this series can be used at temperatures ranging from -20 °C to +100 °C in any industrial application. Particular attention has been paid to providing low-cost calibration that guarantees a maximum Total Error Band of ±1.5 %FS over the entire standard temperature range of -10 °C to +80 °C.
Series 21 Y transmitters are also characterised by being highly resistant to electromagnetic fields. The verified values for conducted and radiated fields are significantly below the limits of the CE standard. These transmitters are also immune to external voltages between the housing and the electrical connection of up to 300 V.
The scope of the vertical range of manufacture, modular design and programmable electronics mean that large-scale customer-specific batches can be easily accommodated. 2-wire (4 to 20 mA) and 3-wire (VDC) output signal versions are available with an extensive selection of pressure and electrical connections supplied as standard.
