0.1%FS Precision Analog Differential Pressure Sensor Differential Level Sensor

Product Description

0.1%FS precision analog differential pressure sensor
HT20  Differential Pressure Sensor

 Introduction: 
The HT20 is a silicon piezoresistive differential pressure sensor with a core of highly stable diffused silicon element. The core is enclosed in a 316L
stainless steel housing, and the pressure is transmitted through a stainless steel diaphragm and sealed silicon oil to the sensitive chip. The sensitive chip does not directly contact the measured medium, forming a fully solid-state structure for pressure measurement, enabling precise measurement of differential pressure. Therefore, this product can be applied in various scenarios that require differential pressure measurement, including harsh and corrosive environments

Product  Features:

1. Stable and reliable performance
2. High resistance to static pressure
3. Cost-effective
4. Utilizes silicon piezoresistive oil-filled pressure-sensitive element

Applications:

1. Differential pressure detectiony
2. Pressure calibration instruments
3. Liquid level measurement
4. Industrial process control

Electrical performance:

1. Power Supply: ≤2mA DC (Typical 1.5mA DC)
2. Input Impedance:3KΩ~6KΩ
3. Output Impedance:2.5KΩ~6KΩ
4. Electrical Connection:Gold-plated Kovar pins or 100mm high-temperature wires

Selection Examples

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.
