Honeywell 51121227-101 Industrial Pressure Sensor

The Honeywell 51121227-101 industrial pressure sensor is a high-precision device designed for industrial applications. It features a stainless steel housing for durability and is suitable for measuring pressure in gases, liquids, and non-corrosive media. With a pressure range of 0 to 1000 bar (0 to 14500 psi), it offers ±0.5% FSO accuracy and fast response times of < 2 ms.

The sensor supports both analog (4–20 mA, 0–10 V) and digital (PWM) outputs, offering flexibility for different system integrations. It is resistant to vibration (20g @ 50-2000 Hz) and shock (100g), and operates in a temperature range of -40°C to +125°C. Additionally, the sensor features overpressure protection up to 150% of rated pressure, signal loss detection, and self-diagnostics
