Intrinsically safe vs explosion proof is a common function of pressure transmitters. When pressure transmitters need to be used in high-risk and explosive places, you must know it!
The explosion-proof pressure transmitter is divided into: intrinsically safe pressure transmitter (explosion-proof mark Exia ⅡC T6 Ga), explosion-proof pressure transmitter (explosion-proof mark Exd ⅡC T6 Gb). Intrinsically safe pressure transmitters must be used with safety barriers. The connection terminals of explosion-proof pressure transmitters must have an explosion-proof electrical connector box and a solid shell.
Sino-Inst offers a variety of explosion-proof pressure transmitters. If you have any questions, please contact our sales engineers.
Intrinsically Safe vs Explosion Proof
It is often necessary to use explosion-proof instruments in industrial sites. The general industrial explosion-proof instruments are mainly explosion-proof and intrinsically safe. So, how to understand the difference between them?
Different from the design concept:
It can withstand the explosive pressure of internal explosive gas mixture. And can prevent the internal explosion from spreading to the explosive mixture around the enclosure of electrical equipment enclosure (zone I explosion-proof technology).
Dangerous gases are allowed to enter the flameproof enclosure, which may cause an explosion. However, the enclosure must have sufficient strength. And each shell joint surface must have a sufficiently long engagement length and a sufficiently small gap. To ensure that the internal explosion will not pass through the flameproof joint and cause the external environment to explode.
Clearance explosion-proof technology. Rely on the gap and mesh length to achieve the effect of cooling and flameout.
Definition of intrinsic safety:
Any electric spark or any thermal effect generated under the conditions specified in the standard (including normal operation and specified fault conditions) cannot ignite the circuits in the specified explosive gas environment (Zone 0/I explosion-proof technology).
It is a “safe” technology that uses suppression of ignition source energy as an explosion-proof method. It is required that the electric spark or thermal effect that the equipment may produce under normal operation or failure state are respectively less than the minimum ignition energy and self-ignition temperature of the explosive dangerous gas. For example: hydrogen 19uJ 560℃.
Intrinsically safe technology is actually a low-power design technology. Therefore, it can be well applied to industrial automation instruments.
Different from the application area
Explosion-proof applicable area: It can only be installed in hazardous locations in Zone 1 or Zone 2.
Intrinsically safe application area:
Exia: Equipment that can maintain explosion-proof performance until two components or other types of failures. Intrinsically safe equipment can be installed in hazardous locations in Zone 0, Zone 1, and Zone 2. Exia intrinsically safe equipment is the only explosion-proof electrical equipment that can be installed in zone 0.
Exib: Equipment that can maintain explosion-proof performance until a component or other type of failure. Intrinsically safe equipment can be installed in hazardous locations in Zone 1 and Zone 2.
Explosion Proof Pressure Transmitter
SIEP489 Explosion proof pressure Transmitter is a microprocessor-based high-performance transmitter. SIEP489 has flexible pressure calibration, push button configuration, and programmable using HART® Communication. We also supply industrial pressure sensors, and explosion proof differential pressure transmitter.
All our electronic pressure transducers can be offered with Explosion-proof. Select explosion-proof pressure transmitters with Ex d certification and 4-20mA output signals for installation. These installations require the use of equipment and enclosures designated as containing internal explosives. This prevents ignition of the explosive environment surrounding the equipment ( Specified) Flameproof area.
The application range of explosion-proof pressure transmitter is as follows:
- Natural gas control system natural gas compressor dispenser;
- Oil well platform wellhead pressure equipment blowout preventer pipeline equipment mine;
- Storage and transportation monitoring of oil tanks and oil products, petrochemical equipment, oil refining;
- Oxygen transmission system and pipeline, hydrogen equipment;
- Power stations, boilers, thermal power units, etc.;
- Petrochemical environmental protection air compressor light industry machinery metallurgy;
- Other pressure measurement environments with explosion-proof requirements.
Of course, intrinsic safety and explosion-proof are not limited to pressure transmitters. Other industrial instruments have this function. To ensure the use of users in dangerous and harsh environments.
