Product Description
MS327 series of vacuum / absolute pressure transducer is a new series of product specially used for vacuum measuring control released in China by German HELM, which fully has solved the problem of difficult vacuum measurement. This series of product has three variants .

Product Feature
1. Fully provided with German HELL made high - accuracy sensing elements, with maximum accuracy up to 0.1% FS

2. Stable and reliable performance, may be continuously operated for a long time, with good long - term stability

3. May apply to measure corrosive medium under special requirements

4. Strong overloading immunity

5. Fast response

6. May be used for hazardous site, with intrinsically safe type Ex ia II CT5

7. Structural diversification, design may be customized at the customer's special requirements.

Product Specification / Models
MS327 series of vacuum / absolute pressure transducer has three variants.MS327G negative pressure transducer.It adopts HELM mono - crystalline silicon thick - membrane sensor.MS327A negative pressure transducer adopts such new high technologies of German HELM as advanced absolute pressure chip, temperature automatic compensation, and normalized circuit commissioning etc. to expand the absolute pressure range to 5KPa, as a minimal, and to greatly enhance the overall accuracy of the product.

MS327CA capacitor thin - membrane absolute pressure transducer is a vacuum pressure gauge made in China through introduction of capacitor thin - membrane from German HELM and internationally advanced calibration and production equipment. This product adopts the capacitor capacity changing principle to work, of which minimum scale may be up to 0.02MPa ~ 200MPa of absolute pressure.

Application / Models
It has widely been used for such fields as pharmaceutical, medical equipment, airspace and aerospace, scientific research, leakage detection, accessories of automation equipment.
