HAMPTON, Va. October 26, 2015 –TE Connectivity Ltd. (TE), a world leader in connectivity, today announced a new backside compensated, headerless 86BC pressure sensor that provides reliable, accurate measurement in harsh environments.
The new 86BC sensor features a 16 mm diameter package, making it a compact, low cost solution ideal for O-ring mounting or OEM applications where compatibility with corrosive media is required. Applications include medical instruments, process control and pressure transmitters, as well as measurement in fresh water, wastewater and for partial vacuum gas. RV and industrial tank level systems also benefit from the small-profile, rugged sensor.
A ceramic substrate attached to the package includes laser-trimmed resistors, which provide temperature compensation and offset correction. An additional laser-trimmed resistor can be used to adjust an external differential amplifier and provide span interchangeability to within plus or minus one percent.
The new sensor features a wide compensated temperature range of minus 20 degrees Celsius up to 85 degrees Celsius and an extended operating temperature of minus 40 degrees Celsius to 105 degrees Celsius. It is available in both gauge and absolute with standard pressure ranges from 0-15 psi to 0-100 psig and from 0-1 bar to 0-28 bar, respectively.
Typical span is 100 mV, with a minimum of 75 mV and a maximum of 150 mV and a plus or minus one percent interchangeable span when the gain set resistor is used to adjust an external differential amplifier.
Encased in a rugged 316L stainless steel housing, this media-compatible piezoresistive silicon pressure sensor provides exceptional accuracy and stability in the most demanding measurement environments. Silicon oil transfers the pressure from the stainless steel diaphragm to the sensing element. The die is mounted in reverse, without the use of a header, contributing to the sensor’s low cost.
Pressure non-linearity is plus or minus 0.3 percent span and pressure hysteresis is plus or minus 0.2 percent span. The use of solid-state circuitry increases the sensor’s reliability and the unit offers a response time of 0.1 ms.
Technical Specifications:
- 16 mm diameter, media compatible, piezoresistive pressure sensor
- Rugged 316L SS construction withstands corrosive media
- 0-100 mV output (75 mv min.; 150 mV max.)
- Wide compensated temperature range: -20°C to +85°C
