Pressure Sensors for Ambulance Oxygen Systems

By Core Sensors | February 1, 2021

Oxygen is a critical piece of equipment on an ambulance. It is vital that the oxygen tanks located on the ambulance never drop too low or worse, completely run out. Pressure sensors are the most commonly used instruments to monitor these tanks. A high quality pressure sensor is able to continuously monitor the pressure left in the oxygen tank and transmit a linear output signal to the ambulances control system. However, there are precautions that must be taken to ensure safe operation.

Instruments that are installed in oxygen enriched environments must be free of contaminants. Common contaminants include hydrocarbons (oils and greases), lint, dirt and more. These contaminants act as fuel that are capable of easily igniting in oxygen environments. Oxygen cleaning is a process to remove these contaminants from the instrument prior to installation.

Core Sensors offers oxygen cleaning on nearly all of it products and can meet recognized standards such as:

  • Praxair GS-38
  • CGA G-4.1
  • Mil Std 1330-D
  • ASTM G93 Test I&II
  • SAE ARP 1176

Once the pressure sensor is oxygen cleaned, it is stored in a vacuum sealed bag and clearly marked as “Oxygen Cleaned”. The pressure sensor should not be opened until it is time to install in the ambulance oxygen control system. Certificates of oxygen cleaning are available upon request.

Example of a oxygen cleaned pressure sensor enclosed in a vacuum sealed bag.

Common Configuration

Ambulances typically carry one or two M style tanks which are used to supply oxygen to the onboard systems. The most common pressure sensor configuration that we encounter for these tanks is:

Model #: CS10-2A02500PS1L032-03

Which translates to:

  • CS10 industrial pressure transducer
  • 1/4″ Male NPT process connection
  • 316L SS wetted material
  • 0-2,500 PSI sealed gauge pressure range
  • 1-5V output signal (10-28VDC supply)
  • 3 meters of integral cable
  • Oxygen cleaned to PraxAir GS-38 standards

While this is the most common configuration, we offer customizable configurations to ensure ease of installation and setup. For example, depending on the power supply available onboard the ambulance, we offer pressure sensors that will operate off of voltages down to 3V. Also, instead of integral cable, we offer high quality connectors such as M12x1 Eurofast and DIN forms A & C.

Pressure ranges over 30 PSI use a monolithic piece of stainless steel. This is beneficial for oxygen applications as there are no oil filled diaphragms that could potentially rupture and contaminate the entire system and there are no O-rings that could rupture and result in a leak.
