GG-H2-EC
Specifications
Input Power:
+24 VDC, 350 mA
Detection Principle:
Electrochemical
Detection Method:
Diffusion
Gases:
Hydrogen (H2)
Ranges:
0-2,000 ppm
0/25%LEL (1% Vol.) (10,000 ppm)
Output Signal:
Linear 4/20 mA (max input impedance: 700 Ohms)
Response Time:
T
50
= less than 10 seconds
T
90
= less than 30 seconds
Accuracy:
+/- 5% of value, but dependent on calibration gas
accuracy and time since last calibration
Zero Drift:
Less than 0.1% of full-scale per month,
non-cumulative
Span Drift:
Application dependent, but generally less
than 3% per month
Linearity:
+/- 0.5% of full-scale
Repeatability:
+/- 1% of full-scale
Wiring Connections:
3-conductor, shielded,
stranded, ≥ 20 AWG cable (General Cable C2525A or
equivalent) up to 1500 ft.
Terminal Block Plug (Field Wiring):
26-12 AWG,
torque 4.5 lbs-in.
Power (green) LED:
Blinks once per second for 60
seconds during power-up. If supply voltage is too
low (<10VDC) or improperly grounded, will blink once
per second continuously. Stays on steady to indicate
power. Blinks twice per second in calibration mode
(10 minute timeout delay).
Status (amber) LED:
Blinks once per second if RFI
(radio frequency interference) is detected.
Fault (red) LED: Stays on steady if supply voltage is too
low (<10VDC).
Enclosure:
Injection-molded, NEMA 12 Washdown-
Duty, polycarbonate sensor housing with hinged lid
and captive screw. For non-classified areas. Optional
18 GA, NEMA 3RX Washdown-Duty stainless steel
enclosure with hinged lid and captive screw. For non-
classified areas.
