CHAPTER 4

TECHNICAL DATA

Specifications

Operating range

Pressure range (1 hPa = 1 mbar) 800 ... 1100 hPa

Temperature range -5°C ... +45°C

Humidity range < 80%RH

Accuracy

Linearity ±0.25 hPa

Pressure hysteresis ±0.05 hPa

Repeatability ±0.05 hPa

Accuracy at +20°C ±0.3 hPa

Temperature hysteresis ±0.3 hPa

Accuracy (-5°C ... 45°C) ±0.5 hPa

Total accuracy after the OFFSET correction (+20 °C, 1000 hPa)

performed by the user is obtained by using the following equation:

Total accuracy = hPan

5.0 +± (5)

where n is the calibration uncertainty

Without the OFFSET correction performed by the user:

Total accuracy (-5 ... +45 °C)±1.00 hPa

Long-term stability ±0.20 hPa/year (typical)

Effect of thermal or mechanical

shocks <0.20 hPa

An error of 1 °C in temperature measurement causes an error of 0.14

hPa in pressure.

General

Supply voltage range 9...16 VDC

Shutdown control with TTL level trigger

<0.7 V module ON

>2.0 V module OFF

Supply voltage sensitivity less than 0.1 hPa
