BP157 Piezoresistive Diffused Silicon Pressure Transmitter
Introduction:
BP157 Piezoresistive Diffused Silicon Pressure Transmitter utilizes the 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.
It is a compact diffused silicon pressure sensors offer a
combination of high performance, durability, and flexibility,
making them an excellent choice for precise pressure measurement in
space-constrained environments.

Ordering tips
1. Determine Pressure Range: Identify the full range of pressures
that the transmitter will need to measure. Ensure the transmitter
you select can accurately measure within this range to avoid errors
and potential damage.
2. Accuracy Levels: Understand the accuracy requirements for your
application. Different transmitters offer varying levels of
precision, so choose one that meets your specific needs for
accurate data.
3. Mounting Options: Identify how the transmitter will be mounted
in your application, whether it requires direct mounting, bracket
mounting, or integration into a panel.
4. For special requirements such as strong vibration, instantaneous
impact force, strong electromagnetic or radio frequency
interference, please inform our company and specify them in the
order.
5. Mounting Options: Identify how the transmitter will be mounted
in your application, whether it requires direct mounting, bracket
mounting, or integration into a panel.
