The GDS-49 (Model 10-0248) two-wire
toxic sensor transmitter provides a scaled
4-20mA current sink output suitable for
long distance transmission to an appropriate receiver device such as a C1 or C2
Protector series controller or GASMAX
transmitter.
Wide Variety of Available Sensors
The GDS-49 is compatible with all GDS
Corp toxic sensors, including oxygen,
hydrogen sulfide, chlorine, carbon monoxide and more. Built-in fault detection
circuity constantly monitors the sensor for
correct operation and sensors can easily be
replaced in the field.
Rugged Detection
The GDS-49 is enclosed in a stainless
steel housing with integrated flame arrestor and is CSA approved for all Class I,
Division 1 and 2 hazardous environments.
For certain highly reactive gases that are
not compatible with stainless steel, the
GDS-49 is also available in a configuration without a flame arrestor that can be
installed as intrinsically safe (IS) with an
approved IS barrier, A standard junction
box is supplied with the GDS-49 for connection to field wiring.
Calibration Required
Initial factory adjustment is completed
by installing a fixed gain resistor on the
sensor. This resistor establishes the range
and provides basic calibration. Since the
GDS-49 electronics are completely sealed
and potted for maximum protection, final
calibration must be performed at the
receiver device in order to meet the rated
accuracy specifications and accomodate
changes in sensor characteristics over
time. GDS Corp. offers single, dual, four,
eight and sixteen + channel controllers
with compatible analog inputs suitable
for final calibration, alarm, display and
retransmission of monitored gas values.
Easy Installation
The GDS-49 includes an XP junction box
and functions with loop voltages ranging
from 10-30VDC; voltage drop across the
GDS-49 is less than 9 volts. An integral
“transient voltage suppressor” protects
the GDS-49 against lightning and other
electrical transients. Non-polarized wiring
elimnates wiring errors.
