Product Description
The BP156 pressure transmitter uses the HT series silicon piezoresistive isolation-membrane oil-filled core as its signal measuring element. The signal processing circuit is housed inside a stainless steel enclosure and converts the sensor signal into a standard output signal. Every unit undergoes rigorous testing and aging screening at the component, semi-finished, and finished-product stages to ensure stable and reliable performance.
- Wide measuring range with a durable all-stainless-steel structure and multiple pressure interface options
- IP65 protection rating in a stainless steel housing
- Adjustable zero point and full-scale output
- High precision with a fully stainless steel construction
- Pressure measurement of non-corrosive gases and liquids compatible with 316L stainless steel
- Marine and aviation industry pressure monitoring
- Industrial on-site processes including petroleum, chemical, metallurgy, power generation, and hydrology
- Hydraulic and pneumatic control systems

- When selecting the product, ensure that the medium to be measured is compatible with the wetted contact parts of the transmitter.
- When placing an order, note that explosion-proof type products do not include digital display heads.
- When ordering transmitters with an LCD or LED display head, the power supply should not be lower than 20 VDC.
- To ensure reliable operation, users are advised to install lightning protection devices on-site and ensure the product and power supply are reliably grounded.
- The rated working temperature range of the fluoro rubber O-ring is -20ºC to 250ºC. When the operating temperature is below -20ºC, an EPDM O-ring seal must be selected.
- The default cable length is 1.5 m, available in three materials. If not specified, polyethylene cable material is supplied. Specify any alternative cable material in the order.
- For special requirements such as strong vibration, instantaneous impact force, or strong electromagnetic / radio frequency interference, please inform our company and specify these in the order.
