Honeywell MLH250BSB14D Pressure Transducer

The Honeywell MLH250BSB14D is a heavy-duty pressure transducer from the MLH series, designed for demanding industrial environments. It combines Application Specific Integrated Circuit (ASIC) technology with a media-isolated, all-metal diaphragm construction to deliver high accuracy and durability across a wide temperature range. This model features a sealed gauge pressure reference with a nominal range of 0 to 250 psi (0 to 17.2 bar). The sensor provides an amplified output signal, typically voltage or current loop, compensated digitally for temperature effects. The pressure port is configured as G 1/4 per DIN 3852-2, suitable for direct hydraulic or pneumatic system integration. The housing is constructed from stainless steel, ensuring compatibility with a wide variety of media including oils, refrigerants, and gases. Electrical specifications include a supply voltage range of 9.5 to 30 Vdc. The total error band is less than ±2% of full scale over the compensated temperature range of -40°C to 125°C. The unit meets RoHS compliance standards and features an environmental sealing rating of IP67/IP69K. Typical applications include HVAC/R systems, hydrogen storage monitoring, air compressors, and general industrial process control.
