  • LITERATURE
GDS GDS-48 Remote Gas Detector Transmitter with Stainless steel sensor head configured with Catalytic Bead for Combustibles LEL (specify gas) with range 0-100% LEL (Lower Explosive Limit). 3-Wire Bridge Output. Available calibrated to Methane (Natural Gas), Ethane, Ethylene, Hydrogen, Butane, Pentane, IPA, Methanol, MEK, Propane, Propylene, Pentane and many others. CSA Certified for Div. 1 Explosion Proof.

Inquiry

The GDS-48 is a three-wire remote sensor for combustible, carbon dioxide or volatile organic compounds that provides a low impedance bridge-style output suitable for long distance transmission to an appropri- ate receiver device such as a C1 Protector, C2 Protector, C2 Quad Protector Controller or GASMAX II gas monitor.

Wide Variety of Available Sensors

The GDS-48 is compatible with all GDS Corp catalytic bead combustible, SmartIR infrared combustible, SmartIR carbon dioxide and photoionization detectors. Sensors can be easily replaced in the field. Interchangeable catalytic bead and infrared sensors allow users the opportunity to switch between the two technologies with minimal impact to controllers and wiring.

Volatile Organics

In today’s highly regulated environment, monitoring for organic compounds, such as benzene and low level gasoline vapors is critical. The GDS-48 with photoionization detector is available in two ranges, 0-50 ppm and 0-300 ppm isobutylene equivalent.

Rugged Detection

The GDS-48 encloses the sensor in a stainless steel housing with integrated flame arrestor that is CSA approved for all Class I, Division 1 and 2 hazardous environments.

Low Cost Solution

The GDS-48 is designed specifically to work with GDS Corp controllers that provide the necessary excitation voltage and bridge-style interface circuitry, often delivering the the lowest overall cost per point. GDS Corp offers single, dual, four, eight and sixteen channel controllers with compatible bridge-style inputs suitable for final calibration, alarm, display and retransmission of monitored gas values.

Easy Installation

The GDS-48 includes an explosion proof junction box with wiring terminals for easy installation and maintenance. An optional splash guard is recommended for locations where water or liquid may be present.

FEATURES

  • Certified for Class I Division 1 Hazardous Locations
  • Interchangeable catalytic bead and SmartIR combustible sensors for combustible applications
  • SmartIR infrared Carbon Dioxide Sensor for ppm to 100% v/v
