Dwyer GSTA-N Nitrogen Dioxide Detector 0-10 Ppm

Product Description

The DWYER GSTA-N is a wall-mount nitrogen dioxide (NO2) gas detector with field selectable analog outputs. It measures NO2 concentration across a range of 0 to 10 ppm and transmits readings via voltage or current output, making it compatible with a wide range of building automation systems, PLCs, and data acquisition equipment. The GSTA-N is designed without an onboard display, placing it in a class of transmitter-style sensors intended for integration into larger monitoring and control systems. Licensed instrumentation technicians and industrial service professionals are the primary installers for this class of device.

The GSTA-N is suited for applications where continuous NO2 monitoring is required in fixed installations. Typical deployment environments include industrial facilities, oil and gas operations, laboratories, agricultural settings, transportation infrastructure, and mining operations. The wall-mount form factor allows for permanent installation in areas where localized gas concentration monitoring is necessary for safety compliance or process control. Because the unit offers field selectable outputs, it can be configured on-site to match the input requirements of the connected control system without requiring a separate signal conditioner.

Key Features

• Measures nitrogen dioxide (NO2) from 0 to 10 ppm
• Field selectable analog output: voltage or current signal
• Wall-mount enclosure for permanent fixed installation
• No onboard display — designed for integration with external monitoring systems
• Suitable for industrial, agricultural, mining, laboratory, and transportation environments

Compatibility

Designed as an OEM-style fixed gas transmitter for integration with building automation systems, PLCs, and analog data acquisition equipment that accept standard voltage or current input signals.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed electrician familiar with low-voltage sensor wiring and applicable electrical codes. Power down the circuit before making any wiring connections. Mount the unit at a height appropriate for NO2 detection, following the sensor placement guidelines in the product documentation and any applicable local or industry safety codes. Verify output signal type selection before commissioning the device with the connected control system.
