Product Description
The BP93420 pressure transmitter uses an HT series diffusion silicon isolation 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 passes rigorous component, semi-finished, and finished-product testing and aging screening to ensure stable, reliable performance.
- Wide measurement range with a stainless steel structure and multiple pressure interface options
- Diverse output signal options, including 4-20mA, 0.5-4.5V, 0-10V, 1-5V, and RS485
- Adjustable zero and full-scale settings for flexible on-site calibration
- High accuracy of ±0.25% (typical) and ±0.5% (maximum) at 25 ºC
- Suitable for measuring non-corrosive gases and liquids compatible with 316L stainless steel
- Applied in industrial on-site processes such as petroleum, chemical, metallurgy, power generation, and hydrology
- Used in the marine and aviation industries
- Suitable for hydraulic and pneumatic control systems

- When selecting the product, please ensure that the medium to be measured is compatible with the contact parts of the product.
- When placing an order, please 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 for the transmitter should not be lower than 20VDC.
- To ensure reliable operation, users are recommended 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 -20 ºC to 250 ºC. When the product's operating temperature is below -20 ºC, an EPDM O-ring seal must be selected.
- The default cable length is 1.5m, available in three materials. If not specified, polyethylene cable material will be supplied. If a different cable material is required, please specify it in the order.
- 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.
