EXPLOSIVE PRODUCTS
| EXPLOSION PROOF DEVICE SAFETY DEVICES: All the mechanisms that are part of the functional structure of the machine, such as: |
|
MECHANISMS WITH BUILT-IN FAIL SAFES
- transmitters
- converters I/P
- solenoid valves, etc.
These are mechanisms used in dangerous areas in accordance with the classifications of the zones and the characteristics of the gases.
Every mechanisms is certified by the individual manufacturer as “Mechanisms with Fail-safe”
LINKED MECHANISMS
Zener Barriers, convenientely installed, limit the voltage and the electrical current used during normal use conditions and/or in case of failure. These are placed in protection of:
- Filling area and control instrumentation
- Circuits placed in dangerous areas
- Devices with built-in fail-safes placed in dangerous areas
CONNECTION WIRES
Wires used include built-in fail safes, or are
Wires that are normally used where the capacity and induction transmitted are calculated into the safety of the system, and therefore in a circuit that is intrinsically safe.
SIMPLE MECHANISMS
All the mechanisms that include devices that generate and/or store no more than 1.5 volts, 100mA, or 25mw; are considered simple mechanisms and therefore not requiring intrinsic protection.
