DIFFERENTIAL PRESSURE SENSOR
Inspect the package for damage. If damaged, notify the appropriate
carrier immediately. If undamaged, open the package and inspect
the device for obvious damage. Return damaged products.
Warning:
• Do not use on oxygen service, in an explosive/hazardous
environment, or with flammable/combustible media.
• Disconnect power supply before installation to prevent
electrical shock and equipment damage.
• Make all connections in accordance with the job wiring
diagram and in accordance with national and local
electrical codes. Use copper conductors only.
Caution:
• Use electrostatic discharge precautions (e.g., use of wrist
straps) during installation and wiring to prevent equipment
damage.
• Avoid locations where severe shock or vibration, excessive
moisture or corrosive fumes are present.
• Do not exceed ratings of the device.
