HT15 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT15 is a silicon piezoresistive pressure sensor with highly stable
diffused silicon elements at its core. It uses the piezoresistive
effect of diffused silicon to measure the pressure of liquids and
gases. The sensor can convert pressure and level measurement
signals into mv electrical output. The sensor has a fast and
accurate interface. The nonlinearity of the sensor is calculated
based on BFSL least square method, which is widely used in air
compressor, refrigeration system and other applications.
Product Features of silicon pressure sensor:
- Utilizes advanced technology and is encapsulated in a 316L
stainless steel housing
- Wide measuring range 0~350KPa~60MpaS
- High reliability and excellent stability
- Various threaded interfaces available for selection
Applications of silicon pressure sensor:- Suitable for measuring non-corrosive gas and liquid pressure with
316L stainless steel compatibility
- Compact design, ideal for applications with limited space
- Used in process control systems for monitoring and controlling
pressure
- Commonly used in refrigeration systems and air compressors for
pressure measurement
Electrical performance of silicon pressure sensor:- Power Supply: ≤2mA DC (Typical 1.5mA DC)
- Input Impedance:3KΩ~6KΩ
- Output Impedance:2.5KΩ~6KΩ
- Electrical Connection:Gold-plated Kovar pins or 100mm
high-temperature wires

1. Pay attention to the fit between the core size and the
transmitter housing during assembly to achieve the
required air tightness
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.
