SPM Flex Gas Detector
Introduction
The SPM Flex gas detector is an extractive gas monitoring system that draws
gas samples locally or from a remote point to a Chemcassette
®
tape-based
optical gas detection system� A wide range of toxic gas Chemcassette cartridges
are available that enable detection of gases used or generated in semiconductor
manufacturing and industrial environments�
The SPM Flex gas detector, available in wall mounted and portable versions,
locally displays gas concentration, alarm, fault and status information via its
backlit color LCD and LEDs� A simple to use 4-button keypad adjacent to the
display provides the ability to set-up, review, operate and make changes to the
detector’s configuration� The intuitive display and menu structure are designed
to require minimal training� The SPM Flex has a local audio alarm with user-
configurable output levels� The detector can be used both indoors and outdoors
in a wide range of weather conditions�
The detector has flexible power and communications capabilities� These include
3 on-board relays, 4-20 mA analog output and Modbus/TCP outputs for signal
and service connectivity� The gas detector is equipped with a USB port for
configuration-sharing firmware updates and data downloads� For web-enabled
devices, web pages are available via the Ethernet port�
Standard operation conditions
The SPM Flex gas detector is designed for use in temperatures between
32ºF and 104ºF (0ºC and 40ºC) and relative humidities between 0 and 100%
(the relative humidities are limited by tape and calibration)� The sample line
will require additional hardware to remove moisture in high relative humidity
conditions where condensing may occur (the sample must be non-condensing)�
Dry conditions may require humidification�
High-altitude applications
The SPM Flex pump is optimized for operation at altitudes between –1000 feet
(–305 meters) and 3000 ft� (945 m) above sea level� At altitudes above 3,000 ft�
(915 m), up to a maximum of 6,000 ft� (1,830 m), contact Honeywell Analytics
for calibration� (At 6,000 feet, pump capacity is reduced 18% and a flow-
system adjustment to the bypass valve is required� This must be performed by a
Honeywell Analytics certified technician� Contact Customer Service�)
