Small Pressure Transducer/Sensor-Low Cost-High Performance

The Small Pressure Transducer/Sensor is characterized by its small size, the shortest can be 5CM. In some occasions where the installation location is small, it has an irreplaceable volume advantage.
Small Pressure Transducer is that the pressure of the measured medium acts directly on the diaphragm of the sensor (stainless steel or ceramics). Make the diaphragm produce a micro-displacement proportional to the medium pressure. The resistance value of the sensor is changed, and the change is detected by the electronic circuit. And convert and output a standard measurement signal corresponding to this pressure.
The interface, casing and electrical interface of the transmitter can be adapted according to the requirements of the user’s industry.

How small can a pressure sensor be?

The Small Pressure Transducer/Sensor is characterized by its small size, the shortest can be 5CM. The interface, casing and electrical interface of the transmitter can be adapted according to the requirements of the user’s industry. The size of Small Pressure Transducer/Sensor also supports customization.

For example, the following product dimensions:

Miniature Pressure Sensor/Transducer

SI-51 Miniature Pressure Sensor/Transducer

Miniature Pressure Sensor is also called Miniature Pressure Transducer. The miniature pressure sensor is a miniature solid-state silicon force sensor integrated with MEMS technology. One-piece miniature stainless steel package. Make it have excellent dynamic performance. Small size, streamlined, strong, compact shape structure.

  • Product size Φ3, Φ5, M6, M8, M10. Can be specially designed according to specific working conditions;
  • Small size, streamlined appearance;
  • split structure. Optional standard voltage, current, digital signal output. Meet the requirements of various working conditions;
  • High dynamic frequency response, steep rising edge;
  • Wide measuring range. Any range between -100Kpa~0-10KPa…60MPa;


Low-pressure pressure transmitter is the application of conventional pressure sensor technology extended to the field of ultra-low pressure. While maintaining the original high performance, the pressure range can be as low as 0-5KPa. The advanced design makes this ultra-low pressure transmitter have the characteristics of fast response and good long-term stability.

The pressure transducer is used to measure various pressures.

The basic structure of its measurement part can be regarded as a space divided into two parts by the sensor. Including the case where one space is the entire universe.

When the pressures of these two parts are not equal, the force acting on the sensor causes the sensor to generate displacement or displacement tendency (force), and the pressure can be measured by detecting the displacement or displacement tendency.

Common sensors include diaphragms, spring tubes, and bellows, among which diaphragms are most widely used in transmitters.

Note that the pressure transmitter needs to be calibrated after a period of use. In order to ensure the accuracy of the quantity.

There are many types of pressure sensors. Such as resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, resonant pressure sensors, etc.

Currently, the most widely used pressure sensors include:

  • Diffused silicon piezoresistive pressure sensor,
  • Ceramic piezoresistive pressure sensor,
  • Sputtering thin film pressure sensor,
  • Capacitive pressure sensor,
  • Sapphire pressure sensor with high temperature resistance.
  • But the most widely used is the piezoresistive pressure sensor, which has a very low price, high accuracy and good linearity.
