Gems develops CVD (Chemical Vapor Deposition), MMS (Micromachined Silicon), Capacitive and Sputtered Thin Film Transducers. The 2200/2600 series CVD pressure transducers produce voltage, millivolt, and current output, suitable for gauge, absolute, compound, and vacuum pressure. In particular, the 2600 features a stainless steel backing for the most strenuous industrial and submersible projects.
The company’s 9000-series digital pressure transducers offer a high degree of reliability over temperatures ranging from -40 to 185 deg. F. These small-size (25mm diameter) transducers feature a non-cumulative stability of <0.05% per year. Manufacturers suggest the 9000-series transducer for noisy, turbulent environments where grounding poses a challenge.
The company also offers MMS-based pressure sensors, such as the 3500-series transducer and 9600-series slimline groundwater monitoring transmitter. With a full-scale accuracy of 0.25%, the 3500-series features an operating temperature of up to 257 deg. F and works in pressure ranges from 0 to 250 psi.
Gems creates adjustable, vacuum, and solid-state pressure switches. The sensitive PS61-series pressure switch functions in pressure ranges from 10 to 4,350 psi, with a favorable pressure-range-to-size ratio that’s ideal for challenging applications. The switch can survive temperatures up to 250 deg. F and is most suitable for pneumatic projects related to medical, off-highway and industrial applications.
Most pressure switches and transducers can be customized with adjustable enclosures and connectors. Extended enclosure varieties for pressure switches include brass, aluminum, reinforced plastic, zinc-housed steel, or stainless steel.
