Overview
The ULTIMA X
®
Series instruments are housed in a flameproof enclosure and are
calibrated at the factory ready for installation.
The instrument components vary somewhat depending on the particular model.
All models are provided with ¾" NPT or M25 x 1.5 cable entries.
The following instrument types are available:
ULTIMA XE
Gas monitor with electronic display in a 316 stainless steel flameproof enclosure
[
Fig. 1]. For combustible gases a catalytic sensor is used and for toxic gases and
oxygen an electrochemical sensor is used. The ULTIMA XE can be ordered with
the standard 4 to 20mA analogue output or with an optional HART [Highway Ad-
dressable Remote Transducer] protocol, which is superimposed on the 4 to 20 mA
signal.
ULTIMA XA
Gas monitor with electronic display in a rugged plastic general purpose enclosure.
The ULTIMA XA can be ordered with the standard 4 to 20mA analogue output or
with an optional HART [Highway Addressable Remote Transducer] protocol, which
is superimposed on the 4 to 20mA signal.
ULTIMA XIR
Gas monitor with electronic display in a 316 stainless steel flameproof enclosure,
based on infrared absorption technology [
Fig. 2]
ULTIMA XI
Gas monitor without display unit in a flameproof enclosure made of stainless steel,
based on infrared absorption technology. The sensors generate an output signal
which is transmitted directly or via a connection box to an appropriate control unit
[
