SPECIFICATIONS
SENSOR AND TRANSMITTER
AVAILABLE SENSORS—
Refer to Appendix G.
CROSS SENSITIVITY—
See Appendix G for Cross Sensitivity information.
CALIBRATION—
Sensors are calibrated at the factory. Gas type and
range are read by the transmitter. Field calibration is
initiated at the detector, at the UD10/UD20 Universal
Display Unit, or by some other HART interface device.
OPERATING VOLTAGE—
24 volts dc nominal. (12 Vdc minimum, 30 Vdc maximum).
Maximum ripple is 2 volts peak-to-peak.
If using the HART function, the installation must comply
with the HART power standard.
POWER CONSUMPTION—
0.8 watt maximum @ 30 Vdc.
CURRENT OUTPUT—
• 4–20 mA (Normal operating mode).
• 3.8 mA indicates calibrate mode.
• 3.5 mA or less indicates a fault condition (2.45 mA
option available).
MAXIMUM LOOP RESISTANCE—
300 ohms at 18 Vdc, 600 ohms at 24 Vdc.
WIRING—
The transmitter has flying leads, 20” long, 600V insulation.
Colors: Red = V+
Black = V–
Green = earth ground
Gauge: 22 AWG (red and black)
16 AWG (green).
WARM-UP—
Warm-up time can last up to 150 seconds.
OPERATING TEMPERATURE—
See Appendix G.
STORAGE TEMPERATURE—
Transmitter: –55°C to +75°C (–67°F to +167°F)
Sensor:
0°C to +20°C (+32°F to +68°F).
Ideal: +4°C to +10°C (+39°F to +50°F).
HUMIDITY RANGE—
15 to 90% RH.
PRESSURE RANGE—
Atmospheric ±10%.
INGRESS PROTECTION—
IP66.
ELECTRO-MAGNETIC COMPATIBILITY—
EMC Directive 2004/108/EC
EN55011 (Emissions)
EN50270 (Immunity).
THREAD OPTIONS—
3/4" NPT or M25.
ENCLOSURE MATERIAL—
GTX Transmitter:
316 Stainless Steel
GTS Sensor Module: PPA (30% carbon filled).
DIMENSIONS—
See Figure 4.
WARRANTY—(For the GTX and GTS)
12 months from date of installation or 18 months from
date of shipment, whichever occurs first.
