The HU73 series features a diffused silicon sensing element with a one-piece stainless steel pressure cavity – no O-rings, no organics exposed to media – eliminating leakage and ensuring ruggedness. A built-in ASIC provides high-precision digital compensation, delivering various analog voltage or 4‑20mA outputs.
The sensor offers ±0.1% non-linearity accuracy, ±0.5% total error band, compensated temperature range -10~70°C, and operating temperature -40~125°C. Compact and robust, it delivers excellent long-term reliability and is ideal for OEM medium to high volume applications.
Semi-custom and fully custom designs are also available.
The HU73 is ideal for demanding industrial applications requiring high ruggedness and reliability. It offers flexible choices of thread sizes, pressure ranges (up to 1,000 psi), electrical connections (cable or connector), wetted materials, and output signals.
