Product Description



BP157 Pressure Transmitter

Introduction of  silicon pressure sensor:

BP157 silicon pressure sensor utilizes the HT series silicon pressure-resistant isolation membrane oil-filled core as the signal measuring element. The signal processing circuit is located inside a stainless steel housing, converting the sensor signal into a standard output signal. The product has undergone rigorous testing and aging screening of components, semi-finished products,and finished products to ensure stable and reliable performance.

Product Features:

1. Wide measuring range, stainless steel structure, diverse pressure interface forms
2. IP65 protection rating stainless steel structure
3. Zero and full-scale adjustable
4. High precision, all stainless steel structure


1. Pressure measurement of non-corrosive gases and liquids with 316L stainless steel
2. Applied in the marine and aviation industries
3. Used in industrial on-site processes such as petroleum, chemical, metallurgy, power generation, and hydrology
4. Utilized in hydraulic and pneumatic control systems

Ordering tips:

1. Measurement range: Determine the required pressure measurement range, i.e. the minimum and maximum pressure values to be measured. Ensure that the measurement range of the selected diffused silicon pressure transmitter meets the requirements of the application.

2. Output signal type: Determine the desired output signal type, such as an analog signal (such as 4-20mA or 0-10V) or a digital signal (such as RS485 or Modbus). Make sure the output signal type of the transmitter you choose is compatible with your control system or device.
3. Accuracy requirements: Determine the required pressure measurement accuracy. Different applications may have different accuracy requirements, choose the diffused silicon pressure transmitter that suits your application needs.
4. Temperature range: Consider the temperature range of the application environment to ensure that the selected transmitter can work properly in this temperature range.
5. Media compatibility: Understand the properties of the medium being measured, such as liquid or gas, and ensure that the selected diffused silicon pressure transmitter is compatible with that medium.
6. Mounting method: Determine the mounting method of the transmitter, such as flange mounting, thread mounting or other methods. Make sure the transmitter you choose matches your installation needs.
