LDES025UE6S 数据手册

LDE Series

Digital low differential pressure sensors

FEATURES

· Pressure ranges from 25 to 500 Pa (0.1 to 2 inH₂O)

· Pressure sensor based on thermal micro-flow

measurement

· High flow impedance

→ very low flow-through leakage

→ high immunity to dust and humidity

→ no loss in sensitivity using long tubing

· Calibrated and temperature compensated

· Unique offset autozeroing feature ensuring

superb long-term stability

· Offset accuracy better than 0.2 %FS

· Total accuracy better than 0.5 %FS typical

· On-chip temperature sensor

· Analog output and digital SPI interface

· RoHS and REACH compliant

· Quality Management System according to

EN ISO 13485 and EN ISO 9001

Specification notes:

1. Sweep 20 to 2000 Hz, 8 min, 4 cycles per axis, MIL-STD-883, Method 2007.

2. 5 shocks, 3 axes, MIL-STD-883E, Method 2002.4.

3. The maximum voltage applied to pin 1 and pins 6 through 10 should not exceed V_S+0.3 V.
