Sensors and Transmitters
Direct Connect Series Gas Sensors - LEL, H2, O2, CO, & H2S use with Beacon Series Controllers
The
direct connect series gas sensors are highly reliable and very cost effective
for the detection of common gas hazards. The direct connect series are available
for LEL, H2 Specific LEL, Oxygen, H2S, and CO for the Beacon 110, 200, 400 &
800
controllers. All sensors are explosion-proof with flame arrestors, and approved.
The direct connect sensors can be used in two different ways. The sensors can be
mounted directly to the controllers as a complete stand alone system, or they
can be mounted to explosion proof junction boxes for remote detection. The flame
arrestors for the explosion-proof versions utilize a patented coating which make
them water repellent. Also, splash guards are available for use in very wet
environments. All of the direct connect sensors are designed to specifically
interface with the Beacon 110, Beacon 200, Beacon 400 & Beacon 800 controllers.
S Series Sensor - 4-20 mA LEL (catalytic), LEL (IR) HC, O2, H2S, CO, or CO2 (IR)
The
S series gas sensor/transmitters are highly reliable and cost effective basic
4-20 mA transmitters for the detection of common gas hazards. The electronics
are encased inside a potted package to avoid damage from mechanical abuse or
corrosion, and this assembly is installed inside an explosion-proof enclosure.
All sensors are explosion-proof with flame arrestors and approved for use in
hazardous atmospheres. Field calibration can be performed easily and quickly by
one person. The flame arrestors utilize a patented coating which make them
water repellent, and splash guards are also available for use in very wet
environments. The transmitter operates from 24 VDC (11VDC to 30 VDC), and
provides a 4-20mA signal which can be connected to a wide variety of
controllers.
M2 - Stand Alone Explosion Proof Transmitter 4-20 mA & Digital Modbus LEL (catalytic, LEL (IR), O2, H2S, or CO
The
M2 is a state-of-the-art transmitter that can operate as an independent,
stand-alone system or as part of a system connected with an analog or digital
signal to virtually any controller, PLC, or DCS. It utilizes a magnetic wand
technique for performing non-intrusive calibration. The M2 provides an automatic
zero drift correction feature, which results in more stable readings and reduces
the need for adjustments due to sensor aging. The M2 housing does not need to be
opened for zeroing or calibration, making it unnecessary to declassify the area
for routine maintenance. It is designed so that a complete field calibration can
be performed by one person. The stainless steel flame arrestor that covers the
sensor is water repellent with a special patented water resistant coating. The
M2 provides a 4-20 mA output in addition to a Modbus digital output. It also has
two levels of alarm with relays, plus a fail alarm with a relay. A digital
display of the gas concentration, as well as alarm and status lights can be
viewed through the front window. The M2 represents the latest leading edge
technology in sensor / transmitters today.
Hydrogen Specific - 4-20 mA 0-2000ppm (solid state sensor), or 0-100% LEL
The
H2 specific sensor/transmitter offers unique proprietary sensor technologies for
hydrogen specific detection in either the % LEL or PPM ranges. By utilizing a
proprietary molecular sieve coating that is built into both our catalytic or
solid state sensors, false alarms from typical hydrocarbon interfering gases are
essentially eliminated. For the LEL range, a special catalytic sensor is coated
with a molecular sieve that eliminates the response to common background gases
like IPA, methane, gasoline, etc. while providing a detection range of 0 –
100% LEL for hydrogen. The hydrogen PPM sensor can reliably detect leaks 20
times smaller than a standard catalytic sensor. This solid state sensor has a
molecular sieve coating on the sensing element, which filters out interference
from other gases and provides a 0 – 2,000 PPM range. Both the LEL and PPM
range sensors are available with 24 VDC transmitters with linear 4-20 mA
outputs.

Controllers
Beacon 110 - Single Channel Wall Mounted Controller
Gas detection should not be complicated. The Beacon 110 is
gas detection simplified. The Beacon 110 is a
powerful, low cost fixed system controller for one point of gas detection. It is
microprocessor controlled, versatile, simple to install and operate, and priced
to be the industry’s best value single gas detection controller. The Beacon
110 can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC). Sensors can
be mounted directly at the Beacon 110 housing, or can be wired remote from the
controller. The 10 amp rated relays are strong enough to directly power external
alarms and horns. The Beacon 110 is also housed in a NEMA 4X rated case for a
weather tight seal. This case design complies with lock out / tag out standards
and can be fully secured. An external reset switch allows the alarm to be
silenced from outside of the controller housing.
Beacon 200 - Two Channel Wall Mounted Controller
The
Beacon 200 is a powerful, low cost fixed system controller for two points of gas
detection. It is microprocessor controlled, versatile, simple to install and
operate, and priced to be the industry’s most economical two point controller.
The Beacon 200 can also accept any 4-20 mA transmitter (2 or 3 wire, 24 VDC).
Sensors can be mounted directly at the Beacon 200 housing, or can be wired
remotely from the controller. The 10 amp rated relays are strong enough to
actuate most external alarms and horns without using slave relays. The
Beacon 200’s housing is rated NEMA 4X for corrosion resistance and a weather
tight seal, and complies with lock out / tag out standards. An external reset
switch allows the alarm to be silenced from outside of the controller
housing.
Beacon 410 - Four Channel Wall Mounted Controller
The
Beacon 410 is a highly configurable, microprocessor-based, flexible and easy to
use 4 channel gas monitor. It simultaneously displays the gas type, readings,
and status for 4 channels of gas detection. Each channel has 3 fully
configurable alarm points. A built-in silenceable audible alarm
alerts you to alarm conditions. Each channel also has 2 dedicated fully
configurable relays and there is a bank of common relays
as well. The common relays can optionally be configured as additional channel
relays allowing up to 3 alarm relays per channel. Each channel
provides a 4-20mA output signal. A digital Modbus
interface for remote logging of data via a Modbus network is standard. A Min-Max
feature retains high & low peak readings for review at any
time. Field calibration is made simple by the easy to use Calibration Mode.
A fully configurable high visibility strobe is available as an option. The unit
can be powered from 115/220 VAC, an external 24 VDC
source, or a 24 VDC backup battery. A trickle charging battery
backup feature is also available as an option. All features and functions of the
Beacon 410 are controlled by easy to use menus on the backlit LCD display.
The form-C (SPDT) relay contacts are rated at 10A, 250V, reducing or eliminating
the need for additional slave relays. All features of the Beacon 410 are built
into the unit so you never need to purchase or maintain any “add-on” cards
or components.
Beacon 800 - Eight Channel Wall Mounted Controller
Gas
detection should not be complicated. The Beaco 800 is gas detection simplified.
The Beacon 800 is a versatile, low cost fixed system controller for one to eight
points of gas detection. It is microprocessor controlled and is capable of
accepting up to 8 separate 4-20 mA sensor transmitters which can be either 2 or
3 wire. The Beacon 800 can be powered by either 24 VDC, or 85-264 VAC. The
Beacon™ 800 is housed in a NEMA 4X rated case for a weather tight seal. This
case design complies with lock out / tag out standards and can be fully secured.
An external reset switch allows alarms to be silenced from outside the
controller housing. The bottom mounted wiring hubs allow for easy wiring. With 3
amp rated relays, the Beacon 800 can be wired directly to a variety of devices
like alarm horns, buzzers, or lights. This eliminates the need for costly
external relays from the controller to devices.
