BP155 Piezoresistive Diffused Silicon Pressure Transmitter
Introduction:
BP155 Piezoresistive Diffused Silicon Pressure Transmitter operate based on the piezoresistive effect in silicon materials.
These sensors are widely used for their high accuracy, reliability,
and ability to measure a wide range of pressures.
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.
Silicon's piezoresistive properties are temperature-dependent. To
maintain accuracy, temperature compensation is performed using
additional circuitry or digital compensation algorithms.
Diffused silicon pressure sensors leverage the piezoresistive
effect in silicon to provide accurate, reliable, and versatile
pressure measurements. Their high performance, combined with robust
and compact design, makes them ideal for a wide range of industrial
and commercial applications.

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.
FAQ:
Q. What is a diffused silicon pressure transmitter?
A diffused silicon pressure transmitter is a device that measures
pressure using a silicon diaphragm with piezoresistive elements.
When pressure is applied, the diaphragm deforms, causing a change
in electrical resistance that is converted into a corresponding
pressure reading.
Q.What are the advantages of using a diffused silicon pressure
transmitter?
A.The advantages include high accuracy, excellent long-term
stability, wide pressure range capabilities, robust construction,
and the ability to operate in harsh environments. They are also
known for their fast response times and low power consumption.
Q: Are you manufacturer?
A: Yes, We are professional sensor manufacturer over 29 years! Our
technical team has more than 10 engineers.
Q: Can you accept OEM service ?
A: Yes, we accept OEM and ODM.
Q: What is the lead time for your pressure transmitters?
Lead times vary depending on the product model and quantity
ordered. We strive to fulfill orders promptly and will provide
specific lead time estimates based on your requirements at the time
of order placement.
