GTR 210

Product catalog summary

Overview

The ADOS GTR 210 Gas Transmitter is designed for continuous gas measurement in both normal and potentially explosive environments. It supports six different sensor technologies to detect toxic, combustible, and inert gases and vapors. The device features a multicolor graphical display with adjustable alarm thresholds and a touchscreen or TouchPad interface for user input. It outputs a proportional current signal (4–20 mA) to a control unit located in a non-explosive area.

Sensor Technologies and Measurement Principles

Sensor Type	Measurement Principle	Measurement Range	Typical Gases	Measurement Accuracy	Response Time (t90)	Temperature Influence	Sensor Life
TGS	Semiconductor	ppm to 100% LEL	Toxic, combustible, explosive gases	±5%	~20 s	5%	No limitation if catalysts not poisoned
VQ	Thermocatalytic (pellistor)	ppm to 100% LEL	Toxic, combustible, explosive gases	±5%	~20 s	2%	No limitation if catalysts not poisoned
GOW	Thermal conductivity	0–5% vol. to 0–100% vol.	Gases with thermal conductivity different from air	±5%	~40 s	2%	No limitation if gases do not attack Al, Re-W, Au
TOX	Electrochemical reaction	0–100% vol.	O2, CO, NH3, NO2, SO2, H2S, others	±3%	<60 s	2%	12 months to 5 years depending on cell
IR	Infrared absorption	0–100% LEL (CH4, C3H8, C2H2)	CH4, propane, CO2	±3%	<30 s	2%	Approx. 5 years
PID	Photoionization	0–200 ppm to 0–2000 ppm	VOC (e.g., toluene, xylenes), chlorohydrocarbons, toxic gases like PH3	±5%	~60 s	2%	12 months

Installation and Mounting

Mounting position is flexible with ±90° tolerance from vertical.
All sensors are plug-in type for easy replacement.

Interfaces and Outputs

Three-wire system with 4–20 mA current output for EX and Standard versions.
Comfort version includes one 4–20 mA current output, four potential-free switching contacts for alarm/fault, and one digital input for alarm acknowledgment.

Applications

The GTR 210 transmitter is suitable for diverse industrial applications including chemical industry, paint and lacquer manufacturing, plastics processing, wastewater treatment plants, gas-fired boiler installations, liquid gas storage, laboratories, oxygen concentration analysis, refineries, refrigeration buildings (ammonia control), and enamel booths.

El transmisor de gas ADOS GTR 210 se apropia para medir de un modo continuo gases en áreas normales y potencialmente explosivas. Usando 6 tecnologías de sensores distintas se pueden medir gases y vapores que ponen en peligro la salud, explosivos e incombustibles. La concentración de gas detectada y de los umbrales de alarma ajustables se visualizan en una representación gráfica multicolor. La entrada por teclado se efectúa mediante una pantalla táctil, o TouchPad. Proporcionalmente a la concentración de gas medida se genera una señal de corriente que se transmite a la unidad de valoración en...
