Vulcain’s sensors’ inherent reliability and stability
characteristics have accounted for the universal
acceptance within a broad spectrum of
commercial and industrial applications.
Catalytic gas sensors are used to detect
hundreds of different fl ammable gases and
vapor concentrations. Toxic gases are detected
through electrochemical cells, while fuel cells are
used for oxygen detection. Moreover, a second
generation of semi-conductor sensors provides
a highly effective solution for a range of different
applications.

Stand- Alone Detectors and Transmitters
The VA-201M provides all the necessary hardware for continuous monitoring of toxic and combustible gases. This unit is primarily "stand alone" and provides alarm - activated relays for simple applications, such as small parking garages.
• Two alarm levels
• 10-step LED display
• 2 high/low DPDT alarm relays
• Audible/visual alarms
• Programmable time delays
• Quick self-test and warm-up
• Calibration status warning
• Innovative and attractive case design
• Simple installation and operation
• Easy field verified caution
• Remote sensor configuration available
• Cost-effective
The VA201R acts as an output to the VA201C. The Relay Module
provides up to 8 relays (DPDT 5A, 30 Vdc or 250 Vac resistive load)
for the indirect activation of fans, louvers, etc at programmable alarm
levels. Since the relay module is an output to the controller it can be
located at any point within the gas detection network.
• Fully compatible with the VA-201C Controller
• Offers either 2, 4 or 8 DPDT relays
• Easy daisy chain installation (RS-485)
• LED visual indication of status next to each relay
Each VA-SQN-8X is equipped with a
built-in noise immune RS-485
communication network providing
the ability to transmit long distances
with the VA-201C controller.
The VA-201C accommodates up to 4
VA-SQN-8X. Features of the VA-201C
controller include:
- Visual Indicators and audible alarm
- Multiple alarm levels
- Programmable time delays
- LCD display
- RS-232C transmission port
The VA-SQN-8X Series, with its
unsurpassed network expandability,
offers a cost-effective centralized
solution.
Combining state of the art technology with a rugged explosion-proof housing the VA-301D analyzes a wide variety of both toxic and combustible gases to high levels of precision. Engineered to rigorous specifications the unit is specifically designed to provide enhanced performance and reliability in the most adverse industrial conditions.
