Intended Use
Dräger PIR 7000 Infrared Gas Transmitter
— For stationary, continuous monitoring of the concentration of flammable gases and vapours
containing hydrocarbons in a suitable atmosphere.
— Alternatively configurable for various gases and vapours as well as measuring ranges.
Dräger PIR 7200 infrared gas transmitter
For stationary, continuous monitoring of the concentration of carbon dioxide in a suitable
atmosphere.
— With analogue output signal from 4 to 20 mA for measuring mode, bi-directional serial
interface and HART
®
interface (optional) for configuration and measuring mode.
— Suitable for use in rough ambient conditions (e.g. offshore).
— For installation alternatively in Ex areas zone 1, 2 or 21, 22 corresponding to device
category 2G, 3G or 2D, 3D or Class I or II, Div. 1 or 2 hazardous areas.
In connection with a central device (e.g. Dräger REGARD 4-20 mA or HART):
— Warning before an explosive concentration level is reached.
— Automatic initiation of countermeasures which avert the explosion hazard (e.g. switching on
ventilation).
— Device fault warning.
— Special calibration mode (blocking of alarm triggering, one-man-calibration).
In connection with the Operating and Display Unit Dräger P 3300 / Dräger P 7300:
— Display of the measured value.
— Configuration of the gas transmitter.
