It improves the working life of the sensor as well as ensure the site safety. SPT81Au pressure sensor selects the high-precision and high stability diffusion silicon piezoresistive pressure sensitive chip produced by famous international manufacturer. The pressure sensitive component is automatically tested by computer and fabricated with zero point correction and temperature compensation. With high accuracy and good stability, it can be widely used in various hydrogen pressure measurement applications. > Electric connection: 00.5mm gold-plated Kovar pin or 100mm flexible silicone rubber wires > Common mode voltage output: 50% input (typ.) > Diaphragm: stainless steel 316L with gold plated > Housing: stainless steel 316L

SPT81Au Gold Plated Pressure Sensor Datasheet > Vented tube: Stainless steel 316L > Media compatibility: High purity hydrogen or mixed gas with high hydrogen content

SPT81Au Gold Plated Pressure Sensor Datasheet Gauge only The suggested installation dimension is O19+0.05 mm. Pressure type Sealed gauge Laser trimming Outer compensated resistor (providing resistor value) Electrical connection

SPT81Au Gold Plated Pressure Sensor Datasheet 1. Please pay attention to protect the diaphragm and the compensated board to prevent any damage or bad performance; 2. It can be used for pressure higher or lower than the range code, but generally needs to be controlled within ±30%FS; 3. Please check the maximum overload of the system before using the product. The maximum overload of the system should be smaller than the maximum overload of the product. Otherwise, the performance and service life of the product will be affected, and even the product will be damaged.
