Đồng hồ áp suất điện tử Keller LEO 2, LEO 2 Ei

Model: LEO 2, LEO 2 Ei

Hãng sản xuất: Keller

Thông số kỹ thuật:

LEO 2 is a compact, micro-processor (µP) controlled, highly accurate and versatile pressure measuring instrument with digital indication. The piezoresistive pressure transducer as the heart of the instrument has gone through extensive pressure- and temperature tests. Its characteristics are stored in the instruments internal EEPROM. The µP of the LEO 2 reads the characteristic values and calculates therefrom the pressure to an accuracy of < 0,1 %FS at room temperature.

The pressure is measured twice per second and displayed. The top display indicates the actual pressure, the bottom display shows the Max.- or Min.- pressure since the last RESET.

Also available as intrinsically safe version (LEO 2 Ei)

Pressure Ranges: -1...3 bar; -1...30 bar; 0...300 bar; 0...700 bar

Accuracy room temperature: < 0,1 %FS

Total Error Band 0…50 °C: < 0,2 %FS

Storage- / Operating Temperature: -20...70 °C / 0...50 °C
