ULTIMA® MOS-5

Gas Detector

Description

The ULTIMA MOS-5 Intelligent Sensor is a micro -

processor-based transmitter designed for use with

MSA’s Metal Oxide Semiconductor (MOS) sensor. This

unit features one person calibration and can virtually

self-calibrate through activation of a magnetic switch

and the application of gas. It is designed to detect

hydrogen sulde in parts per million (ppm) levels and

provide status indication and alarm outputs.

All of the ULTIMA MOS-5 Detector electronics are

contained within an explosion-proof housing so that

sensor information can be processed at the sensor

site. It provides a 4-20 mA signal which is propor -

tional to 0 to 100% of the detection range at the

sensor. In addition, the ULTIMA MOS-5 Detector

includes warning, alarm and fault relay contacts that

can be used to indicate an alarm or fault condition,

and dual redundant ModBus or HART communi -

cations. Congurations with relays, ModBus and

HART are available to meet many needs.

The ULTIMA MOS-5 Detector includes a three (3) digit

LED display. This local digital display continuously

indicates gas concentrations during normal opera -

tion and in the calibration check mode, calibration

prompts during calibration mode, display codes

during the setup mode and eight fault codes.

The ULTIMA MOS-5 Detector has four dierent

operating modes. The rst is the normal operating

mode in which alarms are active and the display and

4-20 mA readings are proportional to the gas

concen tration at the sensor. In the second mode, gas

check mode, the user can apply a gas and check the

sensor response while alarm outputs are inhibited.

The third mode, calibration mode, enables gas to be

applied to the sensor to calibrate the unit. Finally, a

set-up mode allows the user to review or change

setup options such as relay settings, sensor range,

and ModBus parameters.

Selecting Setup Mode on the ULTIMA MOS-5

Detector is accomplished by using the magnetic

switch, HART or ModBus command.
