The GDA 4350 Pump is designed to be used where diffusion sensors are impractical due to environmental or wash down requirements. An advanced 3 wire Non Dispersive Infra red (NDIR) Carbon Dioxide sensor giving a 4-20 mA, 0-20 mA, 0-5 V or 0-10 V o/p over the range of the sensor. Low Temperature version available.
Designed, manufactured and supported locally in Australia.
Housed in an ABS plastic case with an aperture for the gas path. It uses laser LED to give reliable performance. Calibration for non critical safety applications is every 3 years. The low temperature version (suffix LT) operate from - 25°C to 30°C.
Made in Australia and Supported in Australia
|Lift Shaft Wells|
Oxygen sensors are often placed in lift shaft wells to measure the atmosphere prior to entry. Problems arise due to the pressure changes in the left shaft well due to the air movements associated with the lift.resulting in false alarms . There is also an issue associated with safe work permits for access into the lift shaft area when the oxygen sensor requires calibration or replacement. The GDA 4500 system uses a vacuum pump (dc brushless) , a flow fail mechanism and a sensor to extract the gas via a 6mm ID tubing. The Nylon tube is fitted with a filter element to provide dust filtering and prevent mycological build up in the sampling line.
