Symptoms of a Bad or Failing Oxygen Sensor | YourMechanic ...

· You may also observe other engine performance problems, such as loss of power, hesitation, or stalling. Since the oxygen sensor output helps control engine timing, combustion intervals, and the air to fuel ratio, a bad sensor can disrupt these engine functions, causing a rough or irregular engine idle and other engine-related issues. When to replace the sensor. If your vehicle was …

All you need to know about the lambda sensor and exhaust

· The lambda sensor, also called an oxygen sensor, is a small probe located on the car exhaust, between the exhaust manifold and the catalytic was developed by Volvo in the 70s.. If you own a newer car, it will be equipped with 2 lambda sensors. In that case, the second sensor will be located right behind the catalytic converter.

CO2 Tank Safety Precautions |

CO2 tank safety concerns. The primary safety concern is cylinder or tank leakage. While the cylinders or tanks are designed to withstand punctures, the pipes and fittings used to distribute the gas are not. CO2 cylinder pressure is about 860 psi at normal room temperature. Typical CO2 cylinders store about 100 lbs. of liquid CO2.

Leakage detection - detecting CO2 leakage into ammonia

Leakage detection - detecting CO2 leakage into ammonia Two different sensors are available for detecting leakage in CO2/ammonia cascade systems and they both react on the formation of ammonia carbamate which is a very corrosive salt that blocks the pipes and compressor. The sensor Detects a leakage quickly because the conductivity increases significantly when ammonia carbamate is formed. …

Question about optical sensor and leakage detection

· Well here is my ordeal. I have my main return pump connected to an optical level sensor in my overflow box set up as leakage detection to avoid leakages via the overflow. Here is the problem: I had a power outage this am that lasted approx 2 hours. Water raised in the overflow to a level that covered the sensor. Since sensor is connected to pump, when power came back, sensor was under …
