Intrinsically safe approved instrumentation can be installed in hazardous areas zones and connected to other appropriate intrinsically safe equipment. Intrinsic safety is achieved by limiting the amount of electrical power that can enter the protected zone by incorporating zener diode or isolation transformer barriers, and ensuring a certain surface temperature is not exceeded and there are no electrical discharges which may otherwise ignite a potentially explosive atmosphere.
Pressure transmitters are measurement devices which combine amplified 4 to 20 milliamp current loop output signal conditioning electronic module with a transducer for measuring the pressure of a liquid, vapour or gas.
