Digital Manometer LEO Record (Ei) - 1

Digital Manometer with record function LEO Record is an autonomous battery powered instrument with digital display designed to record pressure and temperature over long periods. LEO Record Ei is approved per IECEx for use in hazardous areas. Both the piezoresistive LEO Record as well as the capacitive LEO Record (ideal for low pressure ranges) offer the following advantages: - High measuring accuracy, resolution and robustness - High data security due to the use of a non-volatile memory - Display of the actual pressure and the record status - Recording of the pressure and temperature - Software Logger 5 (included in delivery) for instrument configuration and analysis of measured data - Combination of event-controlled recording and interval recording prevents unnecessary data being recorded (i.e. only measuring the pressure changes...) - Installation data (and comments) of the measuring station can be stored in the instrument - Pressure connection with G1/4” thread (other threads on demand) The pressure is measured and displayed once per second (shortest interval). The top display indicates the actual pressure, the bottom display shows the record status. All LEO Record versions have 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 instruments have the following functions: ZERO The ZERO-function allows to set any value as a new Zero reference. All standard instruments are calibrated in bar. The pressure can be indicated in the following units: bar, mbar/hPa, kPa, MPa, PSI, kp/cm2, (m)H2O RECORD The record can be started or ended with the operating keys. The configuration of the record takes place via interface/software. Optional accessories: - Protective rubber covering - Carrying bag LEO Record Ei with capacitive sensor Pressure Ranges1, resolution, overpressure: 1 mbar 10 mbar 100 mbar 100 mbar 100 mbar Total Error Band (0…50 °C) Long Term Stability typ. 0,1 %FS (Accuracy, incl. temperature error) 0,1 %FS Intrinsically Safe Version, 94/9/CE and IECEx 10 bar Classification: II 2 G Ex ia IIC T4 Gb 60 bar Certifications File: 400 bar 700 bar PTB 05 ATEX 2012 X and IECEx PTB 13.0028X 1000 bar The intrinsic safe version of LEO Record incor- Specifications LEO Record (Ei) capacitive Total Error Band (10…40 °C) Long Term Stability typ. Functions, ranges and accuracy are identical to the standard LEO Record version. PR (relative) / PD2 (differential) Overpressure Negative Overpressure porates an additional protection board. The factory setting of the zero for the ranges ≤ 61 bar absolute is at vacuum (0 bar absolute). For relative pressure measurements, activate “ZERO SEt” at ambient pressure. Instruments > 61 bar absolute or instruments with a relative pressure sensor (label marked with: Range: rel) are calibrated with the zero at atmospheric pressure. Other pressure ranges as well as instruments with relative pressure measuring cells on request For the PD-version, a tube connection Ø 6 mm for the reference is available KELLER Ges. für Druckmesstechnik mbH Companies approved to ISO 9001
