ENVIRO-SEN™

The ENVIRO-SEN™ is a rugged, NEMA 4 industrial grade, temperature controlled enclosure designed to maintain optimum internal operating temperatures over a wide range of ambient temperatures.  In general, gas sensors are usable over a fairly restricted temperature range. If the temperature limits are exceeded, the sensors may sustain permanent damage. With  the ENVIRO-SEN, electrochemical oxygen sensors and non-dispersive infrared carbon dioxide sensors can be operated over an expanded temperature range from as low as -40ºF to as high as +140ºF.

 

Features Benefits
Extends the operating temperature range of both O2 and CO2 systems Eliminates environmental concerns for critical applications
Rugged design Provides years of protection
Economically priced Low cost of acquisition and operation

Production Information
The ENVIRO-SEN is equipped with an industrial grade, thermostatically controlled heater designed to maintain a preset (field adjustable) internal enclosure temperature.

For applications where the external skin temperature of the enclosure may reach as high as +140ºF, the ENVIRO-SEN can be equipped with an optional, thermostatically controlled vortex cooler designed to cool the internal temperature of the enclosure to maintain optimum conditions. The ENVIRO-SEN features a 14 gauge steel, NEMA 4 enclosure  designed for indoor installations as well as for outdoor requirements where exposure to rain and/or snow may be expected.

For applications where condensation of water in the sample gas lines are anticipated, the  ENVIRO-SEN can be used to help maintain sample gas temperatures above the dew point temperature of the gas, thus helping to eliminate condensation prior to analysis. Consult the factory for further information.
