Notes
- Flammable Catalytic Sensor Models
- Poisoning: some compounds will decompose on the catalyst and form a solid barrier over the catalyst surface. This action is cumulative and prolonged exposure will result in an irreversible decrease in sensitivity. The most common of these substances are: volatile lead or sulphur containing compounds; silicones; phosphates.
- Inhibition: certain other compounds, especially hydrogen sulphide and halogenated hydrocarbons, are absorbed or form compounds that are absorbed by the catalyst. The resultant loss of sensitivity is temporary and in most cases a sensor will recover after a period of operation in clean air
- Electrochemical Sensor Models
- Poisoning: Senko sensors are designed to operate in a wide range of harsh environments and conditions. However, it is important that exposure to high concentrations of solvent vapours is avoided, both during storage and operation.
- Oxygen Electrochemical Sensor Models
- Poisoning: Acid gases such as CO₂ and SO₂ will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO₂. Senko oxygen sensors are not suitable for continuous operation in concentrations of CO₂ above 25%.
CALGAS : Calibration Gas
To test and maintain accuracy gas detection systems require regular testing and calibration. GDA can provide you with a complete line of calibration equipment to calibrate all of our gas sensors and detectors. Our calibration gas cylinders all come with N.I.S.T. certification and ISO 17025 approval so you can be confident that you will receive gas with the highest accuracy levels.
SENKO SI-100 : Explosion Proof Gas Detector
SI-100 is an IEC Ex fixed gas detector installed where potential gas hazard occur to measure and monitor oxygen, toxic gas and combustible gas. Through the LCD display the SI-100 shows the concentration of gases present and the status of the unit in real time. It can be connected to a controller with a standard 4-20mA analog output communication. With magnetic buttons a Hot Work permit not required for calibration with no need to open the device.
GDA 4020 : Two Channel Gas Detection Controller
The GDA 4020 control unit has 2 x 4-20 mA i/p with 3 associated programmable relay alarm levels per sensor. There is an independent fault relay. There are 3 x analog o/p’s which can be configured for either channel as 4-20 mA, 0-20 mA, 0-5 V or 0-10 V. The controller has an isolated RS485 o/p which can be configured to drive modbus or an interface to the M2001 mimic panel. All configurations are carried out via the front panel push buttons. The unit requires 24 VDC.
