GSTC Series Carbon Monoxide/Nitrogen Dioxide Gas Transmitter
Description: The GSTC Series Carbon Monoxide/Nitrogen Dioxide Gas Transmitter is designed for monitoring gas concentration in environments such as underground parking garages and loading docks. This series offers ease of field maintenance with industrial-grade replaceable sensors and simplified setup options, making it suitable for applications like garage or loading dock ventilation and mechanical room monitoring. With field-selectable outputs and compatibility with BACnet or Modbus® communication protocols, the GSTC Series provides flexibility and versatility in gas monitoring solutions.
Specifications:
- Sensor: Field replaceable electrochemical, 2 years typical lifespan.
- Range: NO2: 10 PPM; GSTA CO: Switch selectable 200 or 500 PPM; GSTC CO: 500 PPM.
- Output Drift: <5% per year in air.
- Coverage Area: 5000 to 7500 sq ft typical.
- Accuracy: CO: 2% FS, NO2: 3% FS, at the time of calibration.
- Resolution: CO: 1 PPM; NO2: 0.1 PPM.
- Temperature Limits: -4 to 122°F (-20 to 50°C).
- Storage Temperature: For best sensor life, 32 to 68°F (0 to 20°C).
- Humidity Limits: 15 to 90% RH constant; 0 to 99% RH intermittent.
- Response Time: <45 s to 90% CO, <25 s to 90% NO2.
- Span and Zero Adjustments: Via onboard push-buttons or using optional A-449 display; GSTC models: Zero only via BACnet or Modbus® communication protocol.
- Housing: UV resistant glass-filled polycarbonate.
- Output Signals: GSTA: Switch selectable 4-20 mA (loop powered), 0-5 V @ 5 mA, or 0-10 V @ 5 mA; Switch selectable 0-5 V/1-5 V and 0-10 V/2-10 V; Switch selectable normal or reverse output; GSTC: BACnet MS/TP, Modbus® RTU, or Modbus® ASCII (switch selectable) communication protocol.
- Power Requirements: GSTA: Current output: 10-35 VDC, Voltage output: 15-35 VDC or 15-29 VAC; GSTC: 10-36 VDC or isolated 21.6-33 VAC, 5.7 mA @ 24 VDC.
- Electrical Connection: Removable terminal block, knockouts for conduit fitting.
- Calibration: Via onboard push-buttons (LCD model only) or using optional A-449 display. Span gas concentration is field selectable.
- Enclosure Rating: IP64.
- Weight: 1 lb (0.45 kg).
- Compliance: CE.
Benefits/Features:
- Easy Field Maintenance: Industrial-grade replaceable sensors allow for quick and hassle-free maintenance.
- Reduced Inventory: Field-selectable outputs minimize the need for stocking multiple units.
- Simplified Setup: Non-LCD units feature setup display tools for easy configuration.
- Versatile Applications: Suitable for garage or loading dock ventilation and mechanical room monitoring.
With its robust features, versatile applications, and ease of maintenance, the GSTC Series Carbon Monoxide/Nitrogen Dioxide Gas Transmitter offers a reliable solution for gas monitoring in various indoor environments.
