B12 Wet Ozone Transmitter

ATIs B12 Wet Gas Transmitter is perfect for wet environments (100% moisture saturated atmosphere) and consists of a loop-powered 2-wire transmitter and corrosion resistant sensor perfect for direct measurement.

As low as $1,462.00

The B12 Wet Gas System is perfect for the wet scrubber outlets or for other gas streams that might be saturated with water vapor. The B12 consists of a loop-powered 2-wire transmitter and corrosion resistant sensor that is designed to operate at 100% RH. The B12 sensor is made for direct insertion into vent stacks, or may be used in a flowcell if the sample can be pumped to the sensor.

The B12 can be connected to the B14 Alarm Receiver System when remote display and alarm relay functions are needed. When used together it will provide direct digital display of gas concentration, plus 3 alarm setpoints, remote alarm reset input, and retransmitted 4-20mA output.  It's also an option to just use the B12 on its own and tie directly to the users' DCS, PLC or other equipment.

This is the typical installation of the B12 Wet Gas Transmitter

B12 Options (Guide to ordering)

Sensor Module:

Choose the gas detection required for your application.  Range shown is standard range; each sensor can be calibrated for a custom range for an additional $50.  See chart below to see minimum and maximum detection ranges for each sensor.  Contact us for details on this and to verify we can calibrate for your specific range.


Display, Enclosure & Transmitter:

     -NEMA 4X - this is the standard enclosure which is suitable for many environments.  This comes with a separated sensor and 25 feet of cable.

     -Explosion-proof Enclosure - This version is made out of galvanized steel.  The LCD display is not possible with this model.

     -NEMA 4X with LCD display - includes the LCD display and sensor is separated from the transmitter and can be placed up to 25 feet away (cable included). The display is great as it displays the gas concentration.


(NOTE: the display must be ordered at the time the order is placed, this cannot be added later).
