FireBoss - Model 100 - Carbon Monoxide Sensor

FireBoss*100 Carbon Monoxide Sensor - All CO sensors are not alike. The FireBoss toxic 0-25-100-500 ppm CO sensor line has been re-designed and enhanced over a period of two decades of underground mining use, and has evolved as a tough, dependable product with exceptionally long-term stability. Others are often plagued with temperature problems and short life expectancy. We frequently observe sensors still working on their first electrochemical cell ...

OxyBoss - Model 100 - Oxygen Sensor

Oxygen Sensor -- The OxyBoss*100 is a long life product. The cell is guaranteed for one year. Rel-Tek has been manufacturing oxygen sensors for over a decade, and we've learned a lot about making sensors last longer. And, with an initial price comparable to competing "flash-bulb" O2 products, the cost of ownership of the high quality OxyBoss*100, including on-going maintenance, is a lot less. Range is 0-25% O2; uses 10-30VDC, 4-20ma, 2-wire hookup; ...

GasBoss - Model 100 - Combustible Gas Sensor

GasBoss*100 Combustible Gas Sensor -- All combustible gas sensors aren't equal. There are big differences that rarely get mentioned. Our quality catalytic bead sensors last for years, often 5-10 or more, before a head needs to be replaced. Most of our competitors' last a year, maybe two. And, our GasBoss*100 sensors are low current so are approved intrinsically safe (I.S.) not explosion proof (X/P). Competitors' old fashioned high-current sensors are ...

AirBoss - Model 200W - Microprocessor-Based, Linear Air Velocity Sensor

AirBoss 200W Air Velocity Sensor - The AirBoss*200W is a microprocessor-based, linear air velocity sensor with a range of 0-2000 fpm. Quality constructed of plastic and SS to perform in dusty and corrosive underground nuclear waste storage sites, this is a serious product that has no moving parts and is easy to use. Power is from 14-30VDC, 130ma max, three wire hookup. It has a linear 4-20ma output and is classified intrinsically safe in methane ...

GasBoss - Model 1100 - Combustible Gas Sensors

The GasBoss*1100 is a breakthrough in economy and performance. A third the cost of others with similar specs, this unit is designed to serve industry and commercial businesses where budgets are tight and maintenance is minimal. This self contained unit houses an optical infrared source and solid state absorption analyzer, the electronics for providing 4-20mA and 0-1VDC analog outputs, plus a 110VAC power supply, two SPDT individually settable trip ...

HotBoss - Versatile, Multi-Range Temperature Transmitter

The HotBoss*100 is a versatile, multi-range temperature transmitter. Operating from 10-30VDC, this unit generates a 4-20mA analog signal proportional to the probe temperature, over the designated range. Probes are available in three forms, 1) ambient air, 2) flat, copper, bolt-down contact for bolting to pillow block or motor mount and 3) tubular, SS with 1/4" NPT bushing for replacing a grease fitting on a gear box. For ambient monitoring under 60C ...

WetBoss - Relative Humidity Sensor

WetBoss Relative Humidity Sensor - Sensing humidity may seem easy, reflecting back on the original horsehairs and the like, but indeed, precise monitoring of RH is anything but easy. There is a fair amount of snake-oil in the industry, i.e. specs boasting of 0-100% ranges, knowing full well that the very low and very high ends are only estimates, and shrouded by the 5% FS ...

MultiBoss - Model DP - Differential Pressure Transducer

Whether you are monitoring inches of water or psi, the MultiBoss/DP does the job. Select a sensing head from one of six available ranges to suit your needs. Absolute, gage or differential pressure-- just specify the type. Powered from 12-30VDC, 4-20ma linear signal, 3-wire hookup, 35ma max current drain. Optional digital meter continuously displays the reading in 1/2" high, easy to read characters. Housed in a 6x6x4" steel, wall mount enclosure, it has ...

SmokeBoss - Ambient Smoke Monitor

Responds to optical obscuration of air due to smoke particles. Has a 4-20ma, linear output over the 0-10% optical density (OD) range. Powered from 10-30VDC, three wire hookup, draws about 50ma max. Proven in nasty environments, this product is MSHA classified for hazardous methane areas of underground coal mines. The US-Patented design minimizes effects of dust and moisture, while allowing easy field cleaning and recalibration using a built-in optical ...

VibraBoss - Model 100 - Vibration Sensor

A robust, versatile vibration sensor for continuous monitoring of rotating equipment such as large motors, fans, conveyors, etc. Simple to install and monitor; 2-wire hookup, 10-30VDC supply, signal powered, 4-20mA analog output proportional to average vibration velocity, or optionally, displacement. Designed for monitoring equipment with rotational speeds between 200 and 2000 RPM. For rotor speeds less than 500 rpm, "displacement" is generally more ...

ToxiBoss - Toxic Gas Sensor

ToxiBoss is a wall mounted gas sensor with interchangeable sensing heads to cover a wide variety of toxic gas situations. It is approved intrinsically safe for hydrogen (Group B) environments. Its Class I, Div 1 and 2, Group BCD approval means that it may be used in any hazardous gas environment, except acetylene. And, being intrinsically safe, it can be serviced in place without having to disconnect power or to undertake a costly declassification of ...

SafeBoss - Gas Monitoring and Alarm Systems

Rel-Tek has pioneered in gas detection for the alt-fuel transit industry since the inception of CNG buses over a decade ago. Rel-Tek drew on its quarter-century of pioneering product development, experience and know-how from monitoring underground mines to tackle the dynamic alt-fuel transit industry. We continue to maintain that leadership role with the introduction of the SafeBoss sensor/alarm product line. Our new SafeBoss monitoring and alarm ...

Spot-Fire - UV Flame Detector

The “Spot-Fire” was developed for detecting flames from early stage fires. It’s a survey instrument that reacts to flames over a wide area of property and distance. The flame detection design standard is to detect a blaze from a one sq ft pan of gasoline at a distance of 300 feet. Our engineers optimized the physical, optical and software parameters and came up with technology that is far more sensitive. Indeed, the SpotFire can ...

RPMBoss - Electronic Tachometer

Integrated electronics module and probe for idler or shaft monitoring: Easy installation, rugged, accurate, ...
