INTRINSIC SAFETY
Intrinsic safety (IS) is a protection technique or concept for safe operation of electronic equipment in explosive atmospheres and under irregular operating conditions. The concept was developed for safe operation of process control instrumentation in hazardous areas, particularly North Sea gas platforms. As a discipline, it is an application of inherent safety in instrumentation.
Fuel Level Senders are deamed intrinsically safe if the available electrical and thermal energy in the system is always low enough that ignition of the hazardous atmosphere cannot occur. CiES can achieve intrinsic safety in many ways

Fuel Level Senders are deamed intrinsically safe if the available electrical and thermal energy in the system is always low enough that ignition of the hazardous atmosphere cannot occur. CiES can achieve intrinsic safety in many ways
- One way of achieving this is ensuring that only low voltages and currents enter the hazardous area, and that all electric supply and signal wires are protected by limited current source. If wiring to the existing fuel sensors are inside the tank - the following can be applied - the CiES sensor consumes no more than 20 mA and the current source caps the maximum delivered to 50 mA - if a transient voltage were to be introduced the current spike is of extremely short duration.
- The other and more important method CiES Inc. has chosen is to keep all electronics out of the fuel tank. This insures that "NO Electrical Energy" would be present in the tank at all . This is achieved by installing the sensor to the side of the fuel tank and the wires run external to the fuel or fuel hazard.

CIES Inc Fuel Level Sensors are patented and utilize a magnetoresistive sensor and proprietary electronics to determine the position of a float inside the tank.
