Introduction:

AC15 oil filled sensor small profile series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element.
The oil filled sensor is a small profile sensor, designed for pressure port welding or o-ring mounting. Each sensor was strictly temperature compensated for both zero and span.
There are two options of excitation power — current and voltage.
We can also provide port welded sensor(AC17 series)

Features:

* Low cost OEM
* Pressure range:0-100Kpa…7Mpa
* Wide operable temperature range -40~125℃
* Compatible with corrosive media
* Small profile and easily to be welded
* Typical output:0-100mV

Applications:

* Process control
* Fresh and waste water measurements
* Medical instruments
* Pressure transmitters

Pressure Media Liquids and Gases compatible with 316L Stainless Steel

Remark:
1. Best fit straight line
2. Measured at vacuum for absolute (A), ambient for gage (G)
3. Maximum temperature range for product with standard cable is -20°C to +105°C
4. Over the compensated temperature range with respect to 25°C
5. Load resistance to reduce measurement errors due to output loading.
6. Between case and sensing element
