RF & DC Sputtering Unit Vacuum Coater produces thin, homogenous, uniform, pure film coatings of various metals to achieve controlled effects in applications like optics, electronics, materials, thin film coating etc. DHVE offers Different size of Vacuum Thin Film Coating Unit Model 12A4, 15F6, 19F9 & 24F10 with facilities for thermal evaporation, Ion cleaning (bombardment), etc. with accessories for substrate heating, rotation, film thickness monitoring etc. This is a versatile unit both for production as well as research. Optional accessories increase the versatility of the unit making it suitable for a variety of applications, including optical thin film deposition, semiconductors, and micro-electronics. A high speed vacuum pumping system fully integrated with necessary piping and valves operated manually is rated for high gas through- put handling and to produce clean and high vacuum in the chamber. This Vacuum Coating system is wired to operate on 230 V AC, 50Hz single phase power supply / 415 V AC 3 phase power sup
ANALOG PIRANI VACUUM GAUGE DHVE pirani gauges have very wide range of applications where the vacuum measurement needs to be carried between 0.5 mbar to 0.001 mbar. Working principle: The sensor tube of the pirani gauge head consists of a high temperature co-efficient resistance filament. The filament is heated with a constant voltage supply. The variation in pressure in vacuum line causes changes concentration of gas molecules present , in turn the variation in the thermal conductivity of the gas. Hence the heat loss of the electrically heated filament varies with respect to the pressure. This filament is constructed as an arm of the wheat stone bridge. A slight change in system pressure brings larger change in filament resistivity resulting in an imbalance of the bridge. this bridge imbalance current is a measure of pressure which is properly conditioned and displayed on the analog meter.
Digital pirani gauge DHVE DHVE Vacuum Pirani Gauge Controller displays vacuum pressure as measured from a S-PR-GH sensor tube. It displays vacuum measurements based on thermal conductivity of air or nitrogen. The Model DHVE controller covers the range from 0.001bar to 999 mbar, and controls relay with independent set point. ***The optional RS232 along with analog output 0 to 10V and 4 to 20 mA facility can be obtained on request Applications • Controlling high vacuum systems • Fore vacuum pressure monitoring • Safety circuits in vacuum systems • General vacuum measurement & control in the fine and rough vacuum range. • Measurement range 0.001 to 999 mbar • Easy “ATM” and “0” adjustment on the signal conditioner PCB • Space saving rugged design- 1/8 DIN console • Mounts in any orientation • Brass body measuring cell with metal-sealed feed through • With universal power supply – input voltage from 90 ~ 264VAC, frequency 47 ~ 440Hz • Integrated set point adjustment and relay output • Easy To Read 4 Digit Backlit Display • Dual Set Point Controller With 2 Relays (select model DPRG-2GH-SP) • Change Cable Length Without Re-calibrating upt o 8 mtrs
