디지탈 마노메타 Digital Manometer LEO2 ,digital pressure
measuring instrument |
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 % over the temperature range of 0...50°C.
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.
LEO 2 has two operating keys. The left key is to turn the
instrument on, to select the functions and the pressure units. The right key
executes the selected function or unit. The right key is also used to switch
between the MAX.- and MIN.-value.
RESET: With the RESET-function, the MAX.- and
MIN.-value is set to the actual pressurevalue.
ZERO: Any value can be set as a new Zero
reference. The instruments are calibrated in a sealed gauge mode with the
ambient pressure (1 bar) as a Zero reference.The ZERO allows to compensate for
the variation of the barometric pressure or to transfer LEO 2 in an absolute
measuring mode by applying a vacuum and executing the zero.
CONT: The instrument turns off 15 Min. after the
last key function. Activating CONT (Conti-nuous)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, PSI, kPa, MPa.
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.
