Product Description

HT30 Stainless Steel Pressure Probe Element Silicon pressure sensor for Pressure Transmitter

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.

Ordering tips
1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the         
     required airtightness
2. During the assembly of the housing, ensure it is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate.
3. If the measured medium is not compatible with the core diaphragm and the housing material (316L), special instructions should be provided when      placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core due to diaphragm deformation or piercing.
5. Keep the pressure port of the gauge pressure core open to the atmosphere and prevent the entry of water, water vapor, or corrosive media into          the core negative pressure chamber.
6. If there are any changes to the pin leads, follow the label on the actual core for reference.
