3. Core Product Features

Compared with ordinary analog differential pressure transmitters, the IDP10S-TS1B01FM-M2L1 features intelligent interaction, explosion-proof safety, low-temperature resistance and ultra-high stability, with comprehensive performance upgrades:

• Dual-mode HART Intelligent Communication Combining standard 4–20mA analog output and HART digital communication, the transmitter supports real-time remote viewing of pressure values, internal temperature and equipment operating status. Users can remotely adjust measuring range, damping parameters and output mode without on-site disassembly, realizing efficient instrument calibration and daily maintenance, greatly reducing field operation costs.

• Professional Explosion-proof Hazardous Area Adaptation Passed strict FM multi-standard explosion-proof certification, with intrinsically safe circuit design that avoids spark ignition risks. It can be safely deployed in flammable and explosive environments such as petrochemical oil and gas storage and transportation, meeting industrial safety specifications for Zone 0/1/2 hazardous areas, with higher safety redundancy than ordinary transmitters.

• Low-temperature Resistant & Ultra-stable Measurement Custom low-temperature resistant filling fluid and optimized sensing structure prevent measurement failure and data drift in low-temperature medium environments. With 10-year ultra-low drift performance and full-range temperature compensation, it maintains consistent high precision under extreme temperature fluctuation and long-cycle continuous operation.

• IP67 High-strength Industrial Protection Adopting fully sealed integrated aluminum alloy housing and integral waterproof structure, it effectively resists field rainwater immersion, dust accumulation and humid corrosive gas erosion. It adapts to outdoor open-air installation and harsh workshop working conditions, with stronger environmental adaptability than IP66 ordinary transmitters.

• On-site Display & Multi-functional Configuration Equipped with local LCD digital display and button operation function, supporting on-site switching of linear/square root output, positive and negative output reversal and damping adjustment. It is compatible with all Foxboro HART input modules and mainstream industrial control systems, featuring flexible configuration and strong system compatibility.
