0.5-4.5v Ratiometric Sensor Pressure Temperature

In advanced industrial monitoring and control systems, precise simultaneous measurement of pressure and temperature is essential for safety and efficiency. Our sensor platform delivers a reliable 0.5-4.5V ratiometric output, ensuring seamless integration with a wide range of data acquisition equipment. Engineered for demanding applications, the 0.5-4.5v IP65 Waterproof Sensor Pressure Temperature variant features a fully sealed housing rated to IP65, making it resistant to dust, moisture, and temporary submersion. For corrosive or hygienic environments, the SS316L Material Pressure Temperature Sensor construction offers exceptional durability, resistance to chemicals, and compliance with food-grade standards. Beyond the standard voltage output, we provide flexible signal options to suit any system architecture, including the 4-20ma Output Presion Sensor Pressure Temperature for long-distance noise-immune transmission and the I2C Digital Output Presion Sensor Pressure Temperature for direct microcontroller interfacing. All versions incorporate high-stability MEMS sensing elements and digital compensation, realizing excellent accuracy over a wide temperature span.

• Fast response time <5 ms, suitable for dynamic processes
• Power supply: 5 VDC ±10% (other options on request)
• Wide compensated temperature range: -20 to 85°C
• Overload and burst pressure protection up to 3× FS
• CE, RoHS compliant

The 0.5-4.5v Ratiometric Sensor Pressure Temperature represents a breakthrough in compact, multi-sensing technology. It integrates a piezoresistive pressure sensor and a platinum RTD or direct digital temperature element into one robust assembly, delivering two calibrated analog signals through a single process connection. This reduces installation complexity, leak paths, and overall system cost while improving measurement accuracy at the point of interest. The unit is pre-calibrated across its entire pressure and temperature ranges, and the ratiometric output simplifies ADC interfacing by eliminating the need for precision voltage references. Typical applications include water distribution networks, pump monitoring, hydraulic power units, HVAC chillers, and industrial gas analytics. The IP65-rated housing, combined with SS316L wetted parts, guarantees reliable operation even in high-vibration and shock-prone environments. A weatherproof cable gland and optional pigtail connector allow easy field wiring. Below, the comprehensive technical specification table details the product’s key parameters.
