BP157 4-20mA Mini Silicon Pressure Isolation Film Oil Core Pressure
Transmitter Sensor
BP157 PRESSURE TRANSMITRTER
Introduction of pressure transmitter sensor :
The diffused silicon pressure transmitter sensor has a thin film
inside, which is made of silicon material. When the measured
pressure acts on the diaphragm, the diaphragm will be slightly
deformed, and there is a series of small resistance on the
diaphragm, which is called piezoresistive. When the diaphragm is
deformed, resulting in a change in the resistance value of the
piezoresistive, the diffused silicon pressure transmitter usually
has a built-in bridge circuit. The bridge consists of a plurality
of resistors, one of which is piezoresistive. When the
piezoresistive changes, the bridge will produce an output
electrical signal, by measuring the change of the bridge output
electrical signal, you can indirectly know the size of the measured
pressure. The output signal can be analog (such as voltage or
current) or digital (such as digital code).

Ordering trips of pressure transmitter sensor
1. When selecting the product, please ensure that the medium to be
measured is compatible with the contact parts of the product.
2. When placing an order, please note that explosion-proof type
products do not include digital display heads.
3. When ordering transmitters with an LCD or LED display head, the
power supply for the transmitter should not be lower than 20VDC.
4. To ensure reliable operation of the product, it is recommended
that users install lightning protection devices on-site and ensure
that the product and power supply are reliably grounded.
5. The rated working temperature range of the Fluoro rubber O-ring
is -20℃ to 250℃. When the product's operating temperature is below
-20℃, it is necessary to choose an EPDM O-ring seal.
6. The default cable length is 1.5m, available in three materials.
If not specified, it will be supplied with polyethylene cable
material. If you require a different cable material, please specify
it in the order.
7. 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.
