BP157 Pressure Transmitter
Introduction of pressure transmitter sensor :
The BP157 pressure transmitter sensor employs an HT series silicon pressure-resistant isolation membrane oil-filled core as its signal measuring element. The principle pressure sensor revolves around the utilization of diffused silicon technology to measure pressure variations. This type of sensor typically comprises a thin diaphragm made of silicon, which undergoes deformation when subjected to pressure changes. As the pressure exerted on the diaphragm varies, its resistance also alters accordingly.
The mechanism operates based on the piezoresistive effect, where the electrical resistance of the silicon diaphragm changes proportionally with the applied mechanical stress or pressure. When pressure is applied, the silicon diaphragm deforms, causing strain on the material. This strain, in turn, alters the resistance of the silicon, leading to a change in the electrical signal produced by the 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 -20ºC to 250ºC. When the product's operating temperature is below -20ºC, 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.
