HT30 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT30 silicon piezoresistive pressure sensor is a highly stable diffused silicon element. It utilizes the piezoresistive effect of diffused silicon to measure the pressure of liquids and gases. The core is welded together with a standard thread, and it does not use O-ring sealing, making it suitable for a wide range of applications
Product Features of silicon pressure sensor:
1.Utilizing advanced technology and 316L stainless steel housing, along with materials such as titanium and Hastelloy for the diaphragm
2.Employing thick-film circuits for temperature compensation and zero-point correction.
3.Multiple thread interfaces available for selection
4.Welded as one piece, compact size, and high reliability
Applications of silicon pressure sensor: 1.Applied in various industrial process sites, including petroleum, chemical, metallurgy, power, and hydrology .
2.Used in marine and aviation industries
3.Suitable for hydraulic and pneumatic control systems
4.Utilized in process control applications
Electrical performance of silicon pressure sensor: 1.Power Supply: ≤2mA DC (Typical 1.5mA DC)
2.Input Impedance:2.5KΩ~6KΩ
3.Output Impedance:2.5KΩ~6KΩ
4.Electrical Connection:Gold-plated Kovar pins or 100mm high-temperature wires.
