Keller LEO2
Product Information
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).
- RESET With the RESET-function, the Max.- and Min.-value is set to the actual pressure value
- ZERO The ZERO-function allows to set any value as a new Zero reference. Barometric pressure variations can thus be compensated. The factory setting of the Zero for the ranges -1…3 bar or -1…30 bar is at 0 bar absolute. For sealed gauge pressure measurements, activate “ZERO SEt” at ambient pressure. Instruments with ranges > 30 bar are calibrated in a sealed gauge mode at ambient pressure
- CONT The instrument turns off 15 Min. after the last key function. Activating cont (Continuous) deactivates this automatic turn-off.
- UNITS All standard instruments are calibrated in bar. The pressure can be indicated in the the following units: bar, mbar/hPa, kPa, MPa, PSI, kp/cm2
- LEO 2 has 7/16” UNF male thread and is delivered complete with an O-ring seal swivel fitting which allows LEO 2 to be rotated through 360 °. Only minimal tightness is needed to seal up to 300 bar. Process pressure connection is G 1/4” male.
