AD 1000 - Electronic barometer
Product Description
Absolute pressure transmitter for measuring absolute pressuresin closed Systems.
Special features
- High level of accuracy and long-term stability
- Little zero point drift or hysteresis; largely independent oftemperature
- Reduction can be performed to adjust to the altitude of theplace of installation
- Available for a variety of measuring ranges, output signals andsupply voltages
- Available with display (optional)
- Can be calibrated
The AD 1000 absolute pressure transducer is designed fordisplaying atmospheric pressure (BA 1000) and
absolute pressure. At the heart of the unit is an evacuatedmeasurement cell made from an elastic copper
material. The deflection of the measurement cell due to absolutepressure is measured inductively without
making contact. The transmitter emits an electrical outputsignal proportional to the absolute pressure. The
device can be powered using a 24 VDC power supply or a varietyof AC voltages. The pressure port is led
through in the AD 1000 making it suitable for measuring absolutepressures in closed systems.
