1200/1600 SERIES PRESSURE TRANSDUCERS
The 1200 series pressure sensor features stability and toughness via its CVD and ASIC design coupled with a thicker diaphragm. The thicker diaphragm enables these pressure transducer sensors to survive most pressure spikes caused by pump ripple, solenoid valves, etc. The 1600 series extends the packaging options by providing an all welded stainless steel back end for demanding industrial applications. A modular design allows special ordering of fittings, electrical cables, etc. for OEM applications. The ASIC and CVD technology enables Gems™ to offer almost any output over any pressure range.

When your applications require exceptional pressure sensing performance and long-life reliability, look to Gems to deliver. From vacuum to 10,000 psig (-1 to 689 bar), we've got you covered with the industry's largest selection and best choice of pressure transducer technologies. Our capacitance type sensors are ideal for high volume use; sputtered thin film types are the most precise pressure sensors you can buy, and our other types satisfy all requirements in between.
Typical Pressure Transducer ApplicationsPsibar® CVD Type Pressure Sensors
Chemical Vapor Deposition manufacturing methods bond a polysilicon layer to a stainless steel diaphragm at the molecular level to produce a sensor with superior long term drift performance. Common batch processing semiconductor manufacturing methods are used to create a polysilicon strain gauge bridge with terrific performance at a very reasonable price. CVD construction offers excellent price/performance and is the most popular sensor for OEM applications.
Sputtered Thin Film Type Pressure Sensors
Sputtered film deposition creates transducers with maximum combined linearity, hysteresis and repeatability. Accuracy is as high as 0.08% full scale with long term drift as low as 0.06% full scale per year. Phenomenal performance for critical instruments -- Gems sputtered thin film transducers are the jewels of the pressure sensing industry.
Capacitance Type Pressure Sensors
Gems manufactures capacitance type pressure sensors for a wide range of high volume OEM specialty applications. Detecting the capacitance change between two surfaces allows Gems transducers to sense extremely low pressure and vacuum levels. Robust construction allows these units to be used in a wide variety of applications. Coupled with an ASIC, these units provide good price/performance in a host of packaging styles.
MMS Type Pressure Sensors
These transducers employ a micomachined silicon (MMS) diaphragm to detect pressure changes. The silicon diaphragm is protected from the media by an oil-filled 316SS isolation diaphragm; they react in tandem to process fluid pressure. MMS sensors utilize common semiconductor manufacturing techniques that allow for high proof pressure, good linearity, great thermal shock performance and stability in a thin sensor package.
