TO-housing Piezoresistive OEM Pressure Sensor


* Production Description
Pressure sensor, The TO-Housing Piezoresistive, uses advanced ion implantation and micro-mechanical processing technology to produce silicon die which has Wheatstone Bridges and precise mechanical structure, packing sensor as TO type.

The measured pressure is transimitted onto the silicon die through pressure port directly. And the pressure value can be transformed into output voltage signal by linearity relationship. Laser trimming compensates sensor temperature performance.

The sensor could be used on PCB or small space fields to measure gauge, absolute or differential pressure for the gas or liquid.


Power supply: 1.5mA(typ. ) / 10VDC
Pressure reference: Gauge Pressure /Absolute Pressure/ Differential Pressure
Measuring media: Clean air or gas without corrosion
Pressure range: -100kPa~0kPa~35kPa… 700kPa
Overpressure: 2 times FS
Zero output: ± 2 mVDC
Input impedance: 3kΩ ~6kΩ
Accuracy: 0.3%(typ.

* Application:
· Industrial process control
· Level measurement
· Gas, liquid pressure measurement
· Pressure meter
· Pressure calibrator
· Liquid pressure system and switch
· Refrigeration equipment and air conditioner
· Aviation and navigation inspection


* Introduction:

>>> General BS12 Piezoresistive Pressure Sensor
The outline, installation dimension and sealing method of BS12 is strongly interchangeable, it is widely used for measuring pressure which is compatible with stainless steel and Viton;

>>> Assembled BS12N Piezoresistive Pressure Sensor
Put general BS12 pressure sensor into the housing with standard or special thread; Use face type seal or waterline seal; With flexible construction and strict inspecting and screening; The assembled. BS12N sensor has similar application with general type sensor, it can be used for mounting and production of different pressure instruments;

>>> Welded BS12N-H Piezoresistive Pressure Sensor
Put general BS12 pressure sensor into the housing with standard or special thread; And weld sensor with housing together, no O-ring for sealing. The whole product has flexible construction, it has wider application fields than general pressure sensor, can be used for mounting and production of different pressure instruments;

>>> Flush Diaphragm BS12P Piezoresistive Pressure Sensor
Flush diaphragm pressure sensor is a full-welded pressure sensor, it has pressure port G1/2 male or M20x1.5 male, sealing by Viton O-ring at the end of thread. The isolated diaphragm is welded in front of thread port, the whole measure range is 0~100kPa…35MPa. It can be used for food, medicine, sanitation fields in which the media is easily dirty.

>>> Gauge BS12 Pressure Sensor with Vacuum Measurement
We can use general type, assembled type as well as flash diaphragm type gauge pressure sensor to measure pressure below air pressure, the min. Pressure can be around -100kPa.


* Order Note
1. If the working temperature of Viton rubber exceeds the temperature of the rubber specification or be applied in critical environment, please contact us.

2. The material of measuring medium should be compatible with the stainless steel. If it is corrosive, pls specify its material in detail.

3. Please note in the order if you need zero pressure as negative pressure.

4. All specifications are subject to change. Contact Gaohua for specifications and engineering drawings that are critical to your application. Drawings contained in this document are for reference only.
