Pressure transmitter is a sensor that provides real-time measurements. To ensure the safety of working environment, many people monitor or control pressure to achieve their desired value. Pump systems, Compressor, industrial process monitoring, laboratory and petroleum as well as other applications all use electronic pressure sensors as reliable devices for their liquid or gas pressure measurement.
Pressure Transmitter / Sensor
BDP02-01 pressure sensor is a device that has a sensing element and converts the applied force into electrical output signal. With a response time of ≤ 5 ms, the pressure transmitter is well-suited for the majority of industrial applications.
Pressure transmitters, as known as pressure transducers, are used in various applications requiring precise pressure measurement. Gauge pressure sensors, for example, are ideal for controlling and monitoring the compressed air pressure or open tank level.
Our pressure transmitter provides a variety of outputs and measuring ranges. Many process connections are available for application flexibility, which allows you to select right pressure transmitter for your application requirement.

To briefly introduce the principle of the pressure transmitter, here we give an example of a common pressure sensor which has a pressure sensitive diaphragm with strain gauges bonded onto it. This kind of pressure transmitter uses the strain gauge to measure the force acting on them. When the strain gauge is deformed by the applied force, this deformation of the strain gauge causes a change in resistance. Then, through the designed circuit, the change of resistance is converted to voltage or current variations resulting in a corresponding output. Once the applied pressure releases, the strain gauge returns to its original state.
It is important to select a pressure transducer that is suitable for the application. By mounting it, you can measure and monitor the pressure or liquid level to maintain an optimal value.
