ETHYLENE OXIDE (ETO) SENSOR MODEL TOX-ETO/ANA

FEATURES:

•

••

• Linear 4-20 mA output signal •

••

• Interfaces directly to DDC Systems.

•

••

• Automatic low sensitivity check •

••

• Output locked during warm up and

•

••

• Low voltage circuits calibration.

•

••

• Sensor failure indication •

••

• Explosion proof housing.

The sensor module requires a three wire connection to a controller that provides a nominal

28 vdc power and the module sources current in proportion to the gas concentration.

GUIDE SPECIFICATION:

Provide an Ethylene Oxide (ETO) sensor(s) with a range of 0 to 20 ppm (parts per million) and

a linear output of 4 to 20 mA over its range. The sensor shall be housed in an explosion proof

housing and have explosion proof conduit connection to the housing to maintain system

integrity. The sensing element shall be electrochemical and have a life expectancy of two

years. The sensor response time shall reach 90% of level being sensed in 90 seconds. The

sensor shall be powered by low voltage and have a self check capability and an LED to indicate

sensor “Low Sensitivity.” If the sensor fails, its output shall drop to zero to signal the

controller of failed condition. The sensor shall be as manufactured by Toxalert, Inc.

GENERAL DESCRIPTION:

The Model TOX-ETO/ANA, self-contained

Ethylene Oxide sensor module, utilizes

electrochemical technology to provide

accurate monitoring of Ethylene Oxide

O) in the range of 0-20 ppm.

It is designed for fixed installations and use in

ambient monitoring applications.

The sensor module is a 4 to 20 mA transmitter

designed for use in conjunction with

Toxalert’s Models TOX-4ANA and

ToxControl Controllers or any industry

standard 4-20 mA loop controller.
