At the heart of any toxic gas or radioactivity monitoring system are the sensors that detect and measure the threats. RAE Systems’ sensors lead the industry in field-proven sensitivity, effectiveness, reliability, and real-time information delivery. With sensors for specific chemicals and compounds including VOCs and TICs, as well as others for broader detection of gas classes, you can configure the monitor you need. Our innovation, expertise, and dedication to the highest levels of quality enable us to offer threat-detection systems that set the standard for a range of industrial, oil and gas, environmental, defense, and emergency-response applications.
Neutron Radiation Sensors
RAE Systems uses lithium iodide scintillators to detect the presence of neutron radiation in the NeutronRAE II. These scintillators provide fast response, as well as counts per second (cps) data so workers can track the exposure rate as well as total exposure.
Gamma Radiation Sensors
RAE Systems uses two different types of sensors for gamma radiation. Our cesium iodide scintillators provide fast response to low-level radiation to alert users to the presence of radiation before it poses a threat to health. Our PIN diode sensors measure high dose-rate range coverage, so workers can keep track of their exposure rate as well as total exposure. Gamma radiation detection is available in area and multi-gas monitors such as the AreaRAE and MultiRAE Pro, and via personal monitors such as the DoseRAE Pro and GammaRAE II R.
Photoionization detectors (PIDs)
RAE Systems is an innovator and the recognized industry leader in the development of photoionization detectors (PIDs). PIDs use ultraviolet (UV) rays to bombard gas samples and detect a broad range of VOCs such as formaldehyde, methane, and benzene, as well as hydrocarbons that typically occur in oil drilling and refining. These sensors provide an instant reading indicating whether gas is present. This makes PID sensors useful in go/no-go situations where personnel are unsure of what threats they face. RAE Systems offers PIDs that measure in parts-per-million (ppm), as well as specialized PIDs that are highly sensitive to low concentrations of VOCs, and can identify parts-per-billion (ppb). With fast and simple calibration and a large library of correction factors available for a variety of gases, our PIDs set the industry standard for reliability and accuracy.
Toxic Industrial Chemical Sensors
Our electrochemical sensors use chemical reactions to identify and measure specific toxic gases or classes of gases, usually in parts per million (ppm), with advanced filtering providing improved selectivity. This established, reliable technology provides continuous readings. Additionally, these sensors offer the flexibility to be switched within RAE Systems single-gas and multi-gas instruments depending on the threat that you want to monitor. We offer more than 300 individual electrochemical sensor options to help you detect the specific gas for your situation.
Combustible Gas Sensors
RAE Systems’ catalytic and infrared combustible gas sensors help protect personnel and facilities from the risk of explosion or fire due to ignition of flammable gases. These sensors measure gases as a percentage of their Lower Explosive Limit (LEL), the minimum concentration of the gas required to burn if a source of ignition is present.
Maintaining awareness of oxygen levels is paramount to safety. Oxygen (O2) depletion is the most acutely fatal gas threat personnel face and can be caused by a number of factors, including displacement by a heavier gas such as carbon monoxide, or by combustion, including otherwise harmless processes, such as rust. Oxygen enrichment also poses a potential threat because it increases the possibility of combustion and oxidation. RAE Systems’ patented solid polymer and electrolyte O2 sensors are a step forward for the industry because they are safer, don’t use lead, and have an extended life. As a result, these sensors enable a lower total cost of ownership.
