Explosion-Proof Pressure Transducer, 0–2000 psig
Best for high-range hazardous location applications. This NOSHOK model uses a diffused semiconductors and sputtered thin-film sensor for maximum stability, with welded 316 stainless steel and Elgiloy construction. It has no internal O-rings, gaskets, or seals, reducing potential leak points in safety-critical environments. The device outputs 1 Vdc to 5 Vdc and covers 0 to 2000 psig, making it suitable for processors, compressors, and line monitoring where space allows for a larger sensor.
Who it’s best for: facilities needing a rugged, high-range transducer that can withstand harsh locations while delivering stable readings. Why selected: strong metal construction, sealed design, and a proven sensor technology for stability in challenging environments. A potential limitation: larger size and mounting footprint compared with smaller transducers used in tight spaces.
Pressure Transmitter Explosion Proof (0–1.6 MPa)
Better for environments where signal isolation and protection against ingress are critical. This transmitter emphasizes an electrical interface made of premium insulating material for reliable signal transmission and fault protection, plus effective isolation to keep water and dust out. Its design supports long-term industrial use with a focus on longevity through polished surfaces and wear-resistant finishes.
Who it’s best for: teams prioritizing dependable electrical isolation and environmental protection in demanding facilities. Why selected: strong isolation features and robust housing. Caution: the listing notes an emphasis on insulation and protection; ensure compatibility with your existing junction boxes or cabling schemes.
Industrial Pressure Transducer (0–100 MPa)
Best for precision-heavy applications with a 4–20 mA output and LCD readout. The sensor features a robust aluminium XP windowing shell and stainless steel ports, designed to resist vibration, temperature shifts, and electromagnetic interference. It blends high accuracy (within 0.5% FS) with a digital-friendly interface that simplifies integration in automated systems.
Who it’s best for: process control environments needing reliable linear output and visible diagnostics. Why selected: combination of high pressure range, explosion-proof construction, and anti-interference design. Caution: the listing mentions a mixed material build; verify compatibility with your system’s temperature and chemical exposure.
Explosion-Proof Pressure Transducer, 0 psig to 1000 psig
Designed for hazardous location measurement with a compact footprint. It shares the same reliable sensor technology as the 0–2000 psig model, including a sealed design without internal O-rings, gaskets, or seals. The 0–1000 psig range is well-suited for systems where moderate pressure monitoring is essential, such as processing lines or safety valves.
Who it’s best for: facilities needing a mid-range explosion-proof transducer that remains compact and straightforward to install. Why selected: consistent construction and performance with a proven sensor design. Caution: lower maximum pressure range means it’s not ideal for very high-pressure lines.
Explosion-Proof Pressure Transducer, 0–10000 psig
Best for high-pressure monitoring in dangerous zones. This NOSHOK model mirrors the same rugged build as its lower-range cousins but extends to 10000 psig, making it suitable for high-stress industrial lines, compressors, and process equipment. The sensor benefits from a durable welded 316 stainless steel and Elgiloy construction with no internal O-rings, gaskets, or seals to minimize leak risk.
Who it’s best for: operations requiring high-range measurement in hazardous environments. Why selected: high maximum pressure with consistent durability and stability. Caution: higher range often requires careful mounting and signal conditioning to avoid over-pressure damage downstream.
Buying Guide
What defines an explosion-proof pressure transducer?
Explosion-proof designs are built to prevent ignition of surrounding atmospheres by containing potential ignition sources. They typically feature robust housings, sealed enclosures, and materials suited for harsh environments. Look for certifications, enclosure types, and the presence of gasket-free constructions when evaluating options.
Key specs to compare
- Pressure range: Ensure the transducer covers your system’s maximum operating pressure without over-range exposure.
- Output signal: Common options include 1–5 V DC, 4–20 mA, or digital interfaces. Choose according to your control system compatibility.
- Construction materials: Stainless steel and Elgiloy offer corrosion resistance and durability in demanding environments.
- Electrical isolation: Premium insulating interfaces improve signal integrity in electrically noisy facilities.
- Ingress protection: Verify IP ratings or sealing features to withstand water, dust, or chemical exposure.
Choosing the right configuration
- High-range tasks: Favor models rated up to 10000 psig for safety margins in pressurized lines.
- Massive industrial setups: A 4–20 mA output with an LCD display helps operators monitor live values on-site.
- Hazardous environments: Prioritize welded metal housings, gasket-free designs, and proven corrosion resistance.
- Space and installation: Consider mounting footprint and conduit connections when choosing between 1/4 NPT and 1/2 NPT options.
Installation and maintenance basics
- Follow manufacturer torque specs on fittings to avoid leaks or damage.
- Periodic checks of electrical connections help sustain signal reliability.
- Inspect seals and mounting hardware for signs of corrosion or vibration damage in high-stress zones.

FAQ
- What is an explosion-proof pressure transducer? It is a sensor designed to operate safely in hazardous environments by containing any potential ignition within the housing.
- Do these sensors require special electrical connections? Some setups require insulated interfaces and appropriate cabling to maintain signal integrity and protection.
- What range should I choose for a safety-critical system? Select a range that exceeds your maximum operating pressure to avoid over-range operation and ensure durability.
- Can I use these in wet environments? Look for models with high ingress protection and corrosion-resistant housings to withstand moisture and chemicals.
- Is 4–20 mA better than 1–5 V for industrial control? It depends on your control system; 4–20 mA is common in long-distance wiring and noisy environments, while 1–5 V can be more straightforward to interface with modern controllers.
- What maintenance is required for explosion-proof transducers? Regular inspection of seals, fittings, and signal cables is recommended, along with verifying calibration where applicable.
