Overview

The MLH100PSB01B is an All-Metal Media Isolated Pressure Transducer from Honeywell's MLH Series, designed to measure pressures up to 100 PSI. It features a sealed gauge pressure reference and utilizes a 4.5V to 5.5V supply to provide a ratiometric analog output. This rugged sensor is constructed with stainless steel wetted parts, making it compatible with a wide range of liquids and gases in harsh environments.

Why Choose This Part

The sensor features a media-isolated design with no internal O-rings, eliminating potential leak paths and chemical compatibility issues. Its ASIC-based compensation ensures high accuracy and stability over a wide operating temperature range from -40C to 125C. The rugged construction and IP67-rated electrical connector options provide long-term reliability in high-vibration and high-moisture environments.

Applications

HVAC and Refrigeration
Monitoring compressor suction and discharge pressures in industrial cooling systems.
Hydraulic Systems
Real-time pressure feedback for heavy machinery hydraulic fluid loops.
Pneumatic Control
Regulating air pressure in factory automation and industrial pneumatic lines.
Transportation Systems
Monitoring braking system pressure and fuel rail pressure in heavy-duty vehicles.

Getting Started

To interface with the MLH100PSB01B, connect the three-pin Metri-Pack 150 series connector to a 5V regulated DC supply and an ADC input of a microcontroller. Since the output is ratiometric, ensure your ADC reference voltage is tied to the same 5V supply to minimize measurement error. Use the provided transfer function in the datasheet to convert the voltage signal (typically 0.5V to 4.5V) into a PSI value.
