KELLER Pressure

Pressure transmitters Series 21Y

Pressure transmitters are sensors that use additional electronics to compensate for linearity deviations and temperature errors, outputting measurement results as standardised signals. Every transmitter is measured over the entire pressure and temperature profile and compared to the desired signal span.

• Pressure Ranges 0…2 to 0…1000 bar
• Accuracy ±0,5 %FS
• Total Error Band ±1,5 %FS @ -10…80 °C
• Interfaces 4…20 mA, 0…10 V
• Temperature Range -40…100°C

The pressure transmitters of the 21Y series have no internal seal and a high insulation voltage of 300 VDC, and are extremely resistant to environmental influences. The sophisticated compensation circuit makes it possible to specify a narrow total error band. A wide range of pressure connections and electrical connections are available to choose from.
